Crispy 660 CABIN project rises from a client’s request to have a small planing boat with a cabin, a hull to be easy built in plywood and epoxy, a boat powered with an headache-free outboard engine; he will sail the boat as a small week-end cruiser in coastal areas, channels and lakes, taking advantage of the interiors, made by a full size double berth in the lower cabin (with a real marine toilet), a decent amount of space for lockers, stoves and a sink in the cabin ; basically all you need to cruise for a prolonged weekend with the protection of a small cabin, all cooked in a “nu classic” looking small planing boat.

Crispy 660 cabin is the cruising development of our open boat “Crispy” family: an average sized cruising motorboat with plenty of space to fish, sunbath , take a rest and explore the coastal areas or nearbies islands
Hull and structures are derived from Crispy 650 open boat , slightly modified to cope with the different weight of the superstructure, and with a new flared design of the hull topisdes ; the hull is thus made by a structural grid of marine plywood bulkheads linked by a T shaped solid wood keel beam and an array of longitudinal stringers running from bow to transom, this one made by a 58 mm thick sandwich of plywood and solid laminated wood bonded with epoxy; cockpit, deck and superstructure are made by bonded plywood panels, light, stiff and easy to build.
Topsides are made by two layers of 6 mm thick plywood (or solid wood if you prefer) veneers overlapped and bonded on the structure; the boat can be powered with a single or double outboard engine up to 160 HP (single engine) or 2 x 100 HP , giving her a top speed of approximately 31 knots ;
Hull geometry with flared topsides is clearly shown here
Plans are as usual super-detailed with all the developed panels, a huge amount of structural details and several drawings specifically dedicated to systems : electrical, black water, fuel system, bilge system and freshwater system.
All in all Crispy 650 is good choice if you want a classical look coastal cruiser to be built and operated with a reasonable budget , avoiding bigger boats and too expensive powerplants , and she features a modern wooden-epoxy composite hull 15% lighter than a “normal” GRP boat of the same size.
In this kind of boats as usual deck and cockpit arrangement can be widely customized to suit your needs, ranging from pure coastal cruise, to a serious fisherman.
Here it is the interiors layout detailed in plans: a double v berth on the bow, a separate marine toilet, pilot steering position, a galley featuring a couch and sink and stove. cockpit has two lateral seats: hatches on the floor are made in order to easily do maintenance works on systems (fuel tanks, batteries and other systems); two lateral seats can be built in the cockpit
How to build her: the hull is in marine oukume plywood and solid wood battens notched on plywood bulkheads, all glued with epoxy resin, chines are reinforced with glass tapes epoxy laminated. The construction will start setting up the plywood bulkheads on a cheap wood scaffold; we’ll proceed to link the bulkheads with stringers and keel backbone, gluing all together with thickened epoxy, thus making a sturdy and light structural grid. The planking will be made with plywood panels glued on the stringers and bulkheads; chines between panels will be stiffened with glass tapes both inside and outside, the same thing will be done among bulkheads and panels; deck and cockpit will follow the same scheme, plywood panels glued with epoxy on a grid of bulkhead and stringers. The hull will behave like a composite monocoque, light, strong and stiff.
The boat can be customized with all the accessories that you need: fishing rod holders, additional seats, a retractable bimini on the cockpit, a diving equipment rack, and so on.
