Factors Influencing Market Value
Chainplate Inspection Points: Chainplates are through-bolted horizontally at the gunwale bulwark. Sealant degradation in these deck penetrations can cause water intrusion if not properly re-bedded.
Hunter 310 / Hunter 320 – Key Differences & Evolution
Hull & Layout Evolution: The Hunter 320 is a direct revision of the Hunter 310. It gained roughly 9 inches in overall hull length, primarily in the transom and stern profile, which improved cockpit seating and boarding ease.
Tankage Upgrade: The most notable practical upgrade in the 320 is tank capacity. Fresh water capacity was substantially increased to 50 gallons (from the 310’s base 20-gallon supply), making the 320 far better suited for multi-day coastal cruising.
Keel & Weight Distribution: The 320 added 200 lbs of ballast to offset its slightly deeper draft options and tweaked rig geometry, offering marginally better righting moment and stability in heavier air.
