The CORAL SEA
25 CATAMARAN is designed specifically
for the builder who wants the maximum boat for minimum cost and building
time. To this end the vessel features seperate hulls connected by strongly
mounted cross beams. The vessel is demountable for trailing and employs
a simple, easily built, trunkated ‘V’ hull shape. The trunkated ‘V', is
as simple to build as the straight ‘V’, but has better sailing characteristics,
such as less wetted surface, better tacking etc. This yacht is definitely
a case of the most boat for the least work and cost.
The Coral Sea 25 is designed for safe, comfortable family sailing, with
bunks for 4 in 2 seperate hulls. It also has a room for a portable toilet,
small cabin lockers, and a huge cockpit for socializing. There is
good sitting headroom in the hulls. For simplicity and ease of construction
the hulls consist of a plywood shell wrapped around a framework of plywood
bulkheads and timber stringers. This is still the easiest way to construct
a timber boat, and when combined with timber / epoxy construction, is a
very cost effective way to build a sound vessel.
The rig is a simple but efficient ¾ sloop, with a large sail
area for light weather cruising, easily reefed in heavier winds.
The rigidly mounted beams allow the vessel to carry an efficent rig which
can stand up to the weather. The rigging is as simple as possible,
and is based on the KISS principle. Two separate rigs are available, a
standard rig for offshore and open water sailing, and a larger inshore
rig. The choice is at the builders discretion.
Auxiliary power is from an outboard in a separate pod beneath the cockpit
footwell. The vessel features small skeg keels for cruising simplicity,
and efficient transom hung rudders for positive helm control. Steering
as designed is by tiller. The Coral Sea 25
is an easily constructed vessel capable of providing it’s owners with years
of comfortable and fun cruising, or even ocean voyages for the more skillful
and adventurous sailors. |

Mike Waller Yacht Design is a business specialising
in boat plans for amateur boat builders. We custom design, and provide
stock plans for both monohulls and multihulls, mainly catamarans. Other
designs are sailing skiffs and sharpies, as well as power catamarans. Our
designs mainly feature timber construction, in plywood or cedar strip plank
composite construction, using the W.E.S.T. system (wood epoxy saturation
technique). Our designs are intended mainly as cruising boats, although
several have done well in racing |
