Looking for Bluewater Trimaran plans 40-50 feet

Angélique · Feb 20, 2019

BTW, out of size range on this thread, but since in post #12 an ORMA 60 was brought up, Nigel Irens has a 63' cruiser version . . .

Paradox (info button in right top corner)

‘‘ Based on the hull moulds of the ORMA 60 racing trimaran FUFICOLOR, the 19.15m (63ft) PARADOX is the ultimate high performance cruiser racer built for an owner who just likes to sail fast.

Launched in 2010, PARADOX has a significantly shorter rotating wing mast and 3.6m (12ft) narrower beam than an ORMA 60 making it less powerful and easier to sail short-handed with a non-professional crew.

PARADOX has a fully functioning cruising interior with plenty of space and headroom and the Irens design team have incorporated essential cruising solutions like the neat stowaway articulating anchor arm and the tender garage. PARADOX took line honour in the 2013 RORC Caribbean 600 at an average speed of 15 knots. ’’

Beautiful but too big and high cost.
I like the tender garage.

Too bad the Simpson Liona plans aren't available.
Not sure I like the center cockpit on boats in the low 40 foot range- I am alone on this or does it seem to be a better use of space and transom
access for dinghies, fishing, boarding etc with an aft cockpit (and possibly a pilothouse)?

The Liahona from Peabody MA came with a full set of plans I think, so you could track down the leads from that thread to get a copy, and ask Roger Simpson or entitled parties for permission, and what the fee is for a license to build one.

Also the builder of the Liahona that's now for sale in Yarmouth ME could still have a set of plans, or that set of plans might have been brought back to the boat, that can be asked to the seller.

The Liahona set up makes excellent use of space I think, as it leaves room for an aft cabin and a wider center cockpit with still interior space below it.

Maybe you could build a pilothouse instead of the cockpit, and build the aft cabin as low as possible and use the roof as a poop deck for outside space and fishing.

I've posted an Colvin Saugeen Witch with a pilothouse instead of the cockpit on the thread Thomas Colvin's designs → post #25.

The Liahona now for sale in Yarmouth ME looks like excellent built, the 2015 Liahona thread starts with two interior pics of that boat, here's an older ad with older pics in better shape and a higher price, and she's built of top materials including the world top class dutch Bruynzeel full mahogany marine plywood, I'm sure she could be rebuild like new and modificated for a fraction of the effort and price needed to build a new one, and she's not too far from Ontario, at a top yard where you also can work yourself . .

Quote from the above linked old ad:

‘‘ . . . . . Design: "Amakama" is a "open wing" design with net areas between the main hull and the floats between the crossbeams. There are also bow nets. All nets and lashings were replaced with new Dyneema netting in 2008. The main hull is flared well above the waterline to provide additional interior volume, reserve buoyancy and a drier ride.

There are 2 × crossbeams and 6 × bulkheads, two of which are watertight. The forward watertight compartment, which also houses the anchor locker, has both horizontal and vertical bulkheads with inspection port. The bulkhead dividing the engine room from the aft cabin is also watertight. The forward wing cavities contain outside access lockers for deck equipment. There are two additional outside access lockers just forward and outboard of the cockpit. The cockpit has several storage areas in the coamings and under the seats. The port and starboard aft wing cavities each contain a storage locker accessible from bottom hatches for emergency equipment. There is an 18" × 18" Bomar access hatch in each float as well as a small watertight inspection port fore and aft in each float.

The bottom of the main hull is fitted with a minikeel through which a swinging centerboard passes. The centerboard is controlled with uphaul and downhaul lines leading to the cockpit. The single rudder is mounted on a skeg and is operated by an Edson pull-pull cable type wheel steering system. She is very well balanced on all points of sail and will self-steer when close hauled and reaching with the wheel locked.

Construction: "Amakama" was constructed over male molds. Wood surfaces are epoxy coated and glued with epoxy glue.

Hulls are of fiberglass foam sandwich construction. The core material is 5/8" Klegecell PVC foam except for the bow section of the main hull, which is 5/8" Airex PVC foam. The outer skin is 1 oz. chopped strand mat, 24 oz. woven roving and 1 oz. chopped strand mat. The inner skin is 1 oz. chopped strand mat and 24 oz. woven roving. Resin is 1027 waxless slow cure polyester. Total hull thickness is about 3/4". The stem of the main hull is constructed of 14 layers of 1/4" Douglas Fir, laminated with epoxy. This provides a secure attachment for the forestay chainplate. Hulls are painted white with a blue stripe with polyurethane paint. The hull bottoms have a Devoe epoxy barrier coat. They are also coated with 3 coats of blue Pettit Hydrocoat ablative antifouling paint (new 2008).

Main hull decks are of fiberglass foam sandwich construction. The core material is 1/2" Klegecell PVC foam. The outer skin is 1 oz. chopped strand mat, 9 oz. woven roving and 1 oz. chopped strand mat. The inner skin is 1 oz. chopped strand mat and 9 oz. woven roving. Resin is 1027 waxless slow cure polyester. Total thickness is about 5/8". The deck over the galley and navigation station is constructed of 3/8" Bruynzeel mahogany marine plywood to facilitate deck hardware attachment. Deck beams are Douglas Fir. Deck stringers and hardware backing blocks are Ash. Companionway slides and trim, anchor well, rub rails and net attachment cleats are Teak. Decks are painted beige with Interlux Interdeck non-skid polyurethane paint (new 2008).

Ama decks are constructed of 3/8" Bruynzeel mahogany marine plywood covered with 1 oz. chopped strand mat/epoxy.

Crossbeams are Douglas Fir and 3/8" Bruynzeel mahogany marine plywood box beams bonded and coated with cold cure epoxy. Crossbeam fairings are built of cored fiberglass using 1/2" Airex core with reinforcing ribs. Bulkheads are 1/2" and 3/8" Bruynzeel mahogany marine plywood.

The centerboard is constructed of Western Red Cedar sheathed with copper where it turns within the trunk. The rudder and skeg are laminated layers of 1/2" Bruynzeel mahogany marine plywood.

Interior furniture is constructed of 1/4" Bruynzeel mahogany marine plywood. Floors and furniture are framed with Douglas Fir and Spruce.

Through hull fittings and sea cocks are Marelon. Hoses are secured with double stainless steel hose clamps.

Main and aft cabin windows are scratch-resistant polycarbonate (all new 2008). . . . . . ’’
