The 31 is a full size extended cruising boat (several have made world circumnavigations) in a compact length. Options include demountable A-frame akas or fixed wing configurations, outboard or inboard motor auxiliary power, cutter or sloop rigs. Twin cabins, central cockpit and full standing headroom in both cabins are standard. This is the most popular boat in the series. Expect to spend 18 – 24 man months part time for construction.
