Simplicity is a simple,
practical and reliable ocean cruising boat.
Simplicity is intended as a comfortable liveaboard
or long-distance cruising boat, which gives maximum
space and comfort for minimum investment and labor.
The boat's major features all stem from her shoal
draft: that has dictated the rig (center of effort
as low as possible); the hull form (maximum form
stability but sufficient depth and displacement to
maintain good reserve stability); and the raised
deck (important for both strength and stability).
The hull form is a simple modified v hull, with a
flat center section (2.5' wide amidships, which
tapers in width fore and aft). There is a wide,
shallow ballast keel that bolts to this flat, and on
which the boat will sit when beached. Overall draft
is just over 2' with board up, and 5.6' with board
bowsprit & rudder)

are plywood, over plywood bulkheads and frames.
Construction is straightforward, using the
permanent bulkheads, frames and other interior
fittings as molds. Builders have the option of
using a traditional chine or using epoxy coving
and biaxial tape ("liquid joinery" style);
bulkheads and interior joinery can also be
secured with cleats or epoxy and tape. The deck
is laminated plywood over a combination of fore
and aft beams and athwartship beams.

In addition to the gaff rig, she'll also be
offered with a Simplicity rig, which is still
under development. It features a fully
battened, heavily roached mainsail laced to
the mast; the mast is hollow, and designed to
need little support from the rigging. Battens
are easily fashioned from PVC, and lacing the
sails to the masts eliminates any problems
with raising and lowering the sail, making
expensive luff hardware unnecessary. A
sailplan for the Simplicity 42 is below; the
35 would be similar.
