Very, very interesting! Don't really fancy hobbie, prindle, dart, etc rigs on trimarans but hey, at least they're widely available...
We bought a complete Hobie 16 on a trailer to cannibalize for the rig, sails, gudgeons ,etc... Sails alone would have easily exceeded the $400 spent. The Seaclipper 24 we are doing next will be built with a J-24 rig. Jim and John chose the Hobie rig for the very reason that you mentioned : availability.
That's what I thought so... I would consider such kinds of desings if I was to replace my nugget24 in a near future, but now I'm pretty much satisfied... The possibility of recycling one-design rigs is very atractive, except for the somewhat exagerated colourfulness of Hobbie's sails which I dont't particularly like...
The sails are definitely a little on the festive side, but the price was right. If you are thinking about replacing your Piver Nugget at some point, you may want to consider building John Marples' Seaclipper 24. I have a few drawings of it available for download free of charge on my website. It is the big sister of the S.C. 20 , but sports a cuddy cabin instead of the large open cockpit of the S.C. 20.
Jim Brown just released a video on Youtube of the seatrials of the Seaclipper 20 trimaran conducted here in St. Augustine.

This is a center cockpit trimaran professionally (Jayne Marine) built for world ocean cruising. Simple reliable marine equipment of the highest standards. Easy to maintain and repair in remote places. Built with cold molded hulls combining 5 layers of wood/epoxy/ Glasfiber. Perfect for a couple or small family with occasional guests This trimaran sailboat designed by John Marples is a fast, safe, easily handled cruiser that has all controls managed from the center cockpit. It takes its roots from Jim Brown’s center cockpit idea and incorporates the proven streamline hull features of “Constant Camber” construction. The three monocoque cold molded wood/epoxy hulls eliminate the need for interior framing thus reducing weight and improving strength.It features a kick up centerboard for shallow water gunk-holing, 3.3’ up and 5.3’ down.We live and cruise on the boat, currently in the Bahamas and will be in Florida by April. The boat is in excellent condition and is fully equipped for long term cruising with lots of spare parts, tools and daily living accessories. PDF, pictures and videos in request

Auxilary power, accomodations, calculations.
The theoretical maximum speed that a displacement hull can move efficiently through the water is determined by it's waterline length and displacement. It may be unable to reach this speed if the boat is underpowered or heavily loaded, though it may exceed this speed given enough power. Read more.
Classic hull speed formula:
Hull Speed = 1.34 x √LWL
Max Speed/Length ratio = 8.26 ÷ Displacement/Length ratio .311 Hull Speed = Max Speed/Length ratio x √LWL
A measure of the power of the sails relative to the weight of the boat. The higher the number, the higher the performance, but the harder the boat will be to handle. This ratio is a "non-dimensional" value that facilitates comparisons between boats of different types and sizes. Read more.
SA/D = SA ÷ (D ÷ 64) 2/3
A measure of the stability of a boat's hull that suggests how well a monohull will stand up to its sails. The ballast displacement ratio indicates how much of the weight of a boat is placed for maximum stability against capsizing and is an indicator of stiffness and resistance to capsize.
Ballast / Displacement * 100
A measure of the weight of the boat relative to it's length at the waterline. The higher a boat’s D/L ratio, the more easily it will carry a load and the more comfortable its motion will be. The lower a boat's ratio is, the less power it takes to drive the boat to its nominal hull speed or beyond. Read more.
D/L = (D ÷ 2240) ÷ (0.01 x LWL)³
This ratio assess how quickly and abruptly a boat’s hull reacts to waves in a significant seaway, these being the elements of a boat’s motion most likely to cause seasickness. Read more.
Comfort ratio = D ÷ (.65 x (.7 LWL + .3 LOA) x Beam 1.33 )
This formula attempts to indicate whether a given boat might be too wide and light to readily right itself after being overturned in extreme conditions. Read more.
CSV = Beam ÷ ³√(D / 64)

A fast coastal cruising sloop trimaran that is a great weekender for a couple. In a pinch, there is room for two children as well. This boat folds for highway trailering. It has a four-person daysailing capacity. This boat is a lot of fun to sail as it easily cruises at 8-10 knots, with bursts of speed to 15. The construction is particularly streamlined with the Constant Camber panels, minimizing the number of parts and simplifying assembly. Pictures taken by John Marples.

The construction method used to create this John Marples trimaran is called Constant Camber®. Rikki-tikki is a CC40, a center-cockpit cruising design. John has several different Constant Camber® tris of varying lengths, some designed more for racing/cruising. The boats created with Constant Camber® are light, sleek and curvy.

THE PROJECT - MARPLES 35' CC35A TRIMARAN. The Project: Back in 2002, Dave and I, Laura, began discussing retirement plans. Dave had been stationed in Panama in 1995 and thought that it would be a nice place to retire. He began to discuss going from island to island and I asked him how we would get to each island.
