Beneteau First 47.7 (December 2000)
More cruising oriented than its wildly successful little sister, the new First 47.7 nevertheless has similarly impressive performance potential, reports Vanessa Dudley
First is the name chosen by French boatbuilder Beneteau for its range of performance-oriented cruiser/racers. First is also the position occupied at most IMS handicap regattas contested by the First 40.7 model since its release in 1998.
It’s hard to think of another mass production cruiser/racer which has had so much racing success, particularly in Australia where boats like Smile, Fruit Machine and now Fireball have dominated major events including the Hamilton and Hayman Island regattas and the Telstra Cup.
It makes you wonder if the people at Beneteau were really prepared for the phenomenal success of the First 40.7, with more than 284 sold now, including 19 into Australia.

Beneteau First 47.7
Performance-cruiser
This month we are going to look at a series of boats in the mid 40-foot range. It will be fun to see how each designer deals with approximately the same amount of volume and LOA. We can all learn a lot from this style of comparison.
If you go back to the late ’60s and ’70s you’ll find that most production boatbuilders built dual-purpose or racer-cruiser types. This approach died a natural death as pressure on racing boats increased-partially due to the IOR system of rating, and partially due to the new, more intense style of campaigning. This Farr-designed 48-footer takes us back toward the dual-purpose type.
With a D/L of 161 this is not a light boat, but it’s far from heavy. This D/L is pretty normal for a modern, performance-oriented boat. Beam is generous with an L/B of 3.21. To my eye the deck plan indicates a boat with fairly full ends. For fun let’s divide the DWL by the LOA to see how much static sailing length each designer gets out of his LOA. In this case it’s 87 percent. The canoe body shows the typical IMS-style profile going flat through the midsections and kicking up at the ends.

In this case it’s 87 percent. The canoe body shows the typical IMS-style profile going flat through the midsections and kicking up at the ends.
The rudder is very deep and about half the planform of the keel fin. You have your choice of 7 feet, 6 inches, or 9 feet, 2 inches of draft. Consider that there is probably nothing you can do to any boat that will affect its performance more than increasing draft. Note the large fillet radii at both ends of the keel root.
There are several interior layouts available that vary the number of staterooms and berth types. You also have your choice of galley layout. You can have the galley moved forward and adjacent to the elliptical dinette, or you can move the galley aft alongside the starboard side of the companionway steps. This choice is subjective. You lose a settee with the galley forward, and the galley aft is more of a wraparound style for convenience offshore.
You can have four staterooms, which would make a good charter layout. You can have three staterooms, and you can have two spacious double staterooms. There are two heads, with one all the way forward. When you look at the sailplan you may be struck with how far forward the cabintrunk goes, but considering the forward head you should understand why. It’s a tough feature to make look good, and you inevitably end up with a fore “deckette.”
The sailplan is almost masthead. The small offset of the headstay may be to make room for the spinnaker sock. The spreaders are swept. There are two rigs available: a standard rig, and an “S” rig. The S rig is bigger by 108 square feet. This increases the SA/D from 18.89 to 20.89.
There can be little doubt that combining the skills of one of the world’s best design offices with one of the world’s best production builders will provide a very successful end product.

Beneteau First 47.7
Racer or cruiser: it’s all in the options package
by Chris Caswell
boats.com
There are racer-cruisers, cruiser-racers, bluewater boats, performance bluewater boats and a host of other labels for yachts that fall somewhere between pure racing machine and cruising slug.
Unlike most of these boats, however, the new Beneteau First 47.7 is what you make it. Check off some of the options on the order form, and you can create a world cruiser or a family weekender. Check off a few other boxes, and you’ve got a racing yacht that can embarrass purebred custom boats. It’s your choice.
The 47.7 is a Bruce Farr design created without regard to handicap rules, so the hull lines are both powerful and slippery. It has a fine entry, a comfortably wide transom and a choice of keels depending on your sailing needs. Beneteau has sold more than 500 of these yachts overseas; it has just introduced the 47.7 to the U.S. market and the waiting list already stretches for more than a year.
Beneteau startled the racing world with a pair of optimized entries in the Kenwood Cup, and these so-called “beach balls” (nicknamed for their rounded lines) showed their heels to some of the world’s best. At the other end of the spectrum, Beneteau is well known for filling charter fleets worldwide with comfortable and durable yachts. The 47.7 draws on the successful (but now discontinued) 45f5 for a number of features, but adds many new ones.
The deck layout on the 47.7 remains constant, regardless of which interior layout is chosen. The cockpit is wide (too wide to brace your feet on the opposite seat) and well arranged for either cruising or racing with a pair of Lewmars sunk into each coaming (a 58 primary and 48 aft), which should easily handle even the largest headsail. The helmsman’s office is notable for an immense wheel that allows the skipper to plant his rear on the teak-side deck either side of him and use the scalloped bench seat across the transom. Three cockpit lockers (one of which is dedicated to stove fuel) provide ample storage, and the boom is so high that even the tallest sailor can stand on the cockpit seats with impunity. All the sail controls lead to Lewmar 44s with Spinlock stoppers at the forward end of the cockpit.
The rest of the deck is highlighted by excellent non-slip surfaces wherever you might step (including on the side of the cabin, for use when heeled) and built-in Dorade vents in blister mounts with protective guards. The deck is encircled by double lifelines with gates on each side and aft and a varnished mahogany toe rail. The anchor locker forward holds an electric windlass and, just aft, a separate sail locker easily holds spare sails or a deflated tender. At the transom, a fold-down platform is teak-planked and perfect for swimming or boarding the tender.
Two-, three- and four-cabin layouts are offered, and our test boat (provided by Wayne Jones at Southwestern Yacht Sales in San Diego) had the two-cabin version that is likely to be popular with Americans. The salon has immense headroom, and Beneteau gets good marks for providing plenty of grab rails to help you move around this spacious area. A dinette is to starboard with a curved banquette outboard and a smaller bench seat inboard. The table gimbals to handle various heel angles, and there’s ample seating for the whole crew. To port is another settee and the nav station, which also has the electrical panel and a dedicated tool storage.
The galley is aft to starboard so it’s out of the way, and the cook has acres of countertop that wraps around from the double sink past the stove lid (with covering board on rollers) and aft over the refrigerator/freezer. The area aft of the galley that would be a cabin on a different version is left open for storage, although you could throw a mattress in their as a mother-in-law cabin.
The owner’s cabin is forward, spanning the full beam just ahead of the mast. To starboard is a large double berth, a settee is to port along with a hanging locker and there is good storage in drawers and shelves. The head and shower are forward and are surprisingly spacious.
The guest cabin is aft to port, with full headroom and large double berth and two large opening ports. The day head is just forward of the guest cabin, also with shower.
All in all the cabin is cavernous and, though the cherry stain seems dark, the salon remains bright as a result of the big skylight in mid-cabin (which is a light at night) in addition to no fewer than nine opening ports and two hatches.
Three keels are available — 9-, 7.5- and 6-inch — as are either a racing or a cruising rig. We had the deep keel and Sparcraft standard rig with triple sweptback spreaders supporting a 15/16 rig. Actually, it’s more like 31/32, since the headstay is just shy of the masthead. The racing version is five feet taller and has a twin-groove headstay, full spinnaker rig with carbon pole, Max prop and Nitronic rigging.
Undersail, this is a fun boat, although it’s neither an easy singlehander nor a ma-and-pa boat, because there’s a lot of sail to trim. But it’s light and responsive on the helm, with good visibility over the house and from the lee side. As the breeze builds, the 47.7 seems to heel easily until the lee rail nears the water, at which point it stiffens up and feels like it would take a gale to put it down another inch. Once settled comfortably into this groove, the 47.7 goes upwind like the proverbial scalded cat, knocking off eight knots in a 15 knot breeze. Beneteau is so pleased with the performance of this big Farr design that it provides the full polar diagrams as part of the brochure. The 47.7 is broad-reaching, which is another strength, and the wide beam carries a big chute easily.
 

Beneteau First 40.7 and 47.7 Tuning Tips

When the design office of Bruce Farr and Associates started their relationship with Beneteau, few observers would have believed the success and popularity that was to follow. The list of designs is vast that have been drawn by Farr and built by Beneteau. Of late two designs have proved to be devastatingly effective offering value for money, performance, competitive handicapping under both IRC and IMS and genuine cruising potential. They are the Beneteau First 40.7 and big sister the 47.7. With over one hundred and eighty 40.7’s and fifty 47.7’s sailing their success is unquestioned.
Racing fleets of 40.7’s have strongholds in Spain, France, United Kingdom and Australia. Primarily campaigned within large handicap events these boats appear to be equally at home under both of the major handicap rules used around the globe. IMS results and fleet numbers have been impressive with wins at the Copa Del Ray, Hamilton and Hayman Islands and Commodores Cup. At IRC events around our own shores these boats can regularly be seen at or near the front of their respective classes.

Preparation of the 40.7 and 47.7

To gain the most out of these boats in fact any boat that is to be raced seriously you should start your preparation well in advance of the boat going afloat. Set yourself targets agreed between you and your crew on which events are the focus for the year and allocate your time and resources accordingly. Start your preparation before you think necessary. Having enough time in any campaign is a wonderful luxury.

Hull finish

The arguments of which hull finish is better are numerous and personal preference is probably the determinant factor. Whatever your choice, which may be influenced by the venue, how long the boat is to stay afloat, colour or cost make sure that the best possible finish is achieved. Pay special attention to the foils. Check that they are symmetrical and that the trailing edges are as fair as they can be. Prop size may vary, be aware of what you require to satisfy your power requirements and that you are not sailing around with the proverbial dinner plate beneath the boat. Make sure that the strut is fair and that a new anode is fitted regularly.

Rig checks and change

The standard rig and rigging which arrives from the factory will benefit from the following tweaks, changes and checks:
Before stepping the mast check that the spreaders are equal length and that when fitted they are symmetrical with equal aft sweep. Make sure that they locate in position firmly with no play.
For the 40.7 check that the backstay length allows enough headstay tension to be achieved. Many of the boats that we have sailed have needed the backstay to be shortened by 200mm.
Check the headstay length. The length at half adjustment should be 16.335m from pin to pin.
On the 47.7 the same checks should be undertaken. Headstay Length 18.70m from pin to pin.

Running rigging

However serious your program it will benefit from improved running rigging. On the 40.7 the main halyard and centre headsail halyard should be replaced with 10mm Vectran. This material offers massively better stretch resistance than Dyneema / Spectra. Some boats choose to use a 2:1 main halyard, which reduces the weight aloft as an 8mm halyard can be used. To further reduce weight and cost, a 6mm or 8mm Dyneema / Spectra tail can be spliced into the halyard.
For anyone considering sailing offshore one of the wing halyards should also be 10mm Vectran. The principle spinnaker halyard should be Dyneema / Spectra. This offers a little forgiveness to the chutes through its greater elasticity. All the halyards can have their cases removed to reduce windage, weight and friction. Please be sure to coat any Vectran halyard that has its cover removed with Maxi Jacket or some other UV protective coating. Vectran when exposed to sunlight degrades very quickly so an UV shield is very important.
Spinnaker sheets and guys are fine in Spectra / Dyneema with 8mm sheets and 10mm guys the norm. Vectran offers some advantages but the cost implication does not make them a necessity on boats like this.
Genoa sheets should be 10 or 12mm Spectra / Dyneema and have “J” locks or Press Locks fitted to ease sail handling and to accelerate the sail’s passage around the rig when tacking. Cover the clips with either velcro or bicycle inner tube to eliminate the risk of them flogging undone. This will also protect them, the rig and the coachroof.
With the style of mainsheet employed on these boats it is worth splicing the two ends together thus producing an endless system. This eliminates the worry of trying to bear away around a starboard tacker and running out of sheet tail on the weather drum.
Aboard the 47.7 the same materials should be used with increased sizing.

Instruments

Whatever electronics package you have it is imperative to make sure that your system is calibrated and understood by as many of the crew as possible. Allow time to when commissioning a new boat or re-launching to check all readings.
A useful addition to your instrumentation package is a headstay load cell pin. Available from Diverse Yachts at Hamble this system offers you an accurate readout of headstay tension through a remote readout or integrated through your existing instruments. As any trimmer will agree this system is well worth the expenditure.

Crew

Too often on this size of boat the crews strengths are under used. Before sailing ascertain:

• What jobs individuals wish to do?
• What jobs individuals are best at performing?
• What combination of crew gets the boat around the course fastest?

It is important to have your crew motivated but on the flip side it is also important to make the best use of the crew available to you. Some difficult decisions may be needed to ensure that the primary roles within the crew are filled by the crewmembers that offer the best skills in these areas. Be objective and select rather than divide up tasks equally. Everyone aboard must understand that whatever their contribution, it is having a positive effect. Canvass opinion from someone detached from the program as to crew selection and task allocation.
Make the hard decisions when planning your program rather than having to make changes at an event or during a race.

Ready to set up the rig

Both the 40.7 and 47.7 as standard have fractional three spreader rigs. Spreaders are aft swept to approximately 10 degrees. The rigs are relatively simple having no running backstays or check stays. Backstay adjustment is via a Navtec hydraulic ram.
Obviously the set up of each boat will vary as to what sails are used and the conditions to be encountered. Each sailmaker will no doubt have their own guidelines as to set up. The biggest factors to consider will be the mainsail luff curve and mast rake. This will vary between sailmakers, these are the basics which I have use when sailing the 40.7 with North Sails.
Before starting the rig set up make sure that the verticals (caps) and diagonals (intermediates) are all slack.
Mast foot / butt position. On the 40.7 the butt is located within a track with three set positions. If possible a new track should be fabricated with holes set 12mm apart. If using the standard track use the forward hole. At deck level the “J” measurement should be set at 4.41m. This measurement may vary depending on what is declared on your rating certificate. On the 47.7 “J” should measure 5.21m.
The base headstay length that I would recommend is 16.335m. This should be set with the turnbuckle half open. Make sure that your boat has an adjustable headstay.
Aboard the 47.7 the butt position as shown should see the front face of the mast 35mm from the main bulkhead.
Before tensioning the rig, basic checks to ensure that the rig is central in the boat at both deck level and at the hounds should be carried out. To check the hounds are central suspend a crewmember over the side on a bosuns chair. Wait for a minute allowing the halyard to take up. Now lower the human weight so that the halyard can be marked by using a batten laid flat on the deck extending over the gunwale and a permanent ink pen. Repeat from side to side making adjustments where necessary. Always check aloft to ensure that the halyard has clear passage.
Once the rig is centred, the butt set, the headstay at base and the rig set at “J” we are ready to start the laborious task of tensioning the caps. Make sure you have a good pair of large adjustable spanners to hand. On the standard rig in both the 40.7 and 47.7 a mast jack is not supplied. Unfortunately “hard work” is the order of the day here. To make life a little easier tension the backstay fully. With little or no diagonal / lower tension the rig will bend dramatically. Do not be alarmed. The compression in the spar will bring the hounds closer to the deck thus allowing the caps to be tensioned more easily. You should, with the correct tools be able to get to within 2 / 3 turns of the required tension before sailing. Ease the backstay off and you are now ready to tension the lowers and diagonals. The lowers D1’s should be hand tight plus four turns. The D2’s and D3’s should be hand tight plus three turns. Remember to sight up the back of the spar to keep the rig as straight as possible. On the 40.7 you should now have approximately 85mm of pre bend, on the 47.7 approximately 105mm of pre-bend should be showing. The above adjustments are guidelines that should provide a sensible base setting to start from.

Time to go sailing

Allow plenty of time for final rig adjustments. Three or four hours should suffice. Ideal conditions for this task is 12 to 15kts of breeze with flat water. You do not need all of the crew present, however you will need someone confident at working aloft whilst sailing. To finish tensioning the caps sail close hauled on each tack and assess the amount of slack in the leeward cap shroud. Adjust the leeward shroud one turn at a time. As mentioned you should need no more than three turns to give the required tension. Do not expect to eliminate all the slack from the leeward shrouds completely.
To tune the diagonals whilst sailing sight up the back of the luff track in the mast. Sight from above and below the gooseneck to see how the rig is behaving. The acid test for diagonal shroud tension? The mast must be straight sideways. Hopefully we should only be moving the diagonals by only one or two turns.
Repeat this procedure again and again until the rig stays in column even with 100% backstay applied. The compression loading on the spar will make it this difficult to achieve. The rewards when this is accomplished are well worth the toil and trouble. Be aware that the diagonals pull the rig aft thus straightening it, as well as sideways.
On fine tuning the location of the mast butt look for an even fore and aft bend. Sight the first 600mm of mainsail coming off the rig from the gooseneck through to the second spreader. If the mainsail entry is too deep and round move the butt aft to bend the spar thus giving a finer entry. If the entry is too flat / fine move the butt forward to round the entry. Do not be afraid to move the butt in 12mm increments so you can easily see your adjustments.
The magic in these rigs is achieving the correct amount of headstay tension without runners, checks or jumpers. Therefore tuning has to be just right to allow the main to set correctly while transmitting the optimum tension down the headstay for a given windspeed and sea state. On the 40.7 I prefer to use five headstay lengths which are shown with other quick adjustments and sail choices in the table below.

A couple of tips for sailing

When sailing these boats remember they are relatively heavy and need to be coaxed around the race course. Build speed aggressively out of tacks by pressing on the genoa. Make sure that there is strong communication between the helmsman and the trimmers through the period of acceleration. The headsail trimmer should during the speed build be talking about the angle to the helm while the mainsheet trimmer calls the speed build. When turning the boat always consider how much speed you can afford to scrub off when making a tight turn. For instance making a tactical turn when position the boat will be much faster than the optimum VMG tack when sailing upwind. Do not be afraid to ease backstay when accelerating out of tacks.
Given the relatively long spreaders that these boats carry it is necessary to sheet the headsails very hard around the rig. Make sure you have strong correctly positioned spreader patches. Check them for wear regularly.
Be aware that if your are moving your headstay length that you will need a well documented table of settings which show the sail, the position of the halyard and headstay.
Use crew weight as much as possible to minimise the amount helm needed for any manoeuvre. A common mistake in these boats is not easing enough vang at the weather mark and not keeping all the available weight out as far as possible until the turn downwind has been completed. Make sure that all of the crew understand that it is far better to hoist one boatlength later having completed a smooth bear away, rather than compounding a poor away by starting the hoist to early. Have a designated crewmember that continually encourages everyone to hike as hard as possible. Have them remind everyone prior to the mark rounding how important a smooth bear away is. Someone should take responsibility for the vang at every weather mark, easing when necessary to allow the bear away and then pulling on back to the downwind mark. A clear call is needed from the helmsman / tactician when to commence the hoist.
Upwind practise sailing in different modes. Using more mainsheet, traveller and backstay work at finding your “point mode”. Do not be afraid to ease the outhaul 25mm when trying to sail high. This will create a little more weather helm giving the driver more feel. This mode is particularly effective on tight laylines or when trying to force a weather boat to tack away thus opening your options.
Work at finding your “fast forward mode”. From your upwind VMG numbers sail two tenths quicker. Press on the headsail, sail with the main down track and ease the backstay slightly. This mode is particularly useful when covering an opponent or when looking to get to a heading shift first.
Downwind in above 12 kts of breeze roll the boat aggressively into the gybes. Have someone in the middle of the boat co-ordinate the weight transfer. Use as little helm as possible for the turn.
When gybing in under 10 kts of breeze lower the main halyard 150mm jut before the gybe. This allows the main to pass trough the backstay more easily. Once the turn is completed re-hoist the main.

Useful tips about the boat

• Upgrade the genoa car pullers. Line and block size should be increased.
• Upgrade the vang with extra purchase and include ratchet blocks in the system.
• Position as a visual guide a marked batten on the backstay.
• Padding on bottom lifelines to aid hiking.
