Schorpioen, makes a lot of sense as a coastal cruiser for two. It seems well designed for something like the Great Loop of the Eastern half of North America because the outriggers easily retract for the locks, and the mast is reasonably dropped in its tabernacle. This would seem to work well in Europe, coastal and canal cruising. But I'd put it in a container and ship it over.
I'd likely tow a June Bug, or similar skiff as a dinghy/pantry/tanker for more extended runs. Though the true shoal draft limits the need for a dinghy. PB&F showed a pair of Tortise for dinghy service but they were tied off on the extended floats which seems to burden the retraction process. I wouldn't have it that way, and Ed Medalis told me in emails we exchanged he would not have placed them out there either.
If the boat was on a flat rack, the boat could be lifted off and launched in one move, and the flat rack lifted onto the wharf on the second move. I would guess that it would be cheaper than hiring in a portable crane for any standard launching.

Cruising cats and tris are not all that much better... Cruising cats by and large cruise at just slightly over what a monohull does (and often less) and even with a best case scenario you might save a week in crossing the Atlantic. Yeah, I know there are cats and tris that go like the wind but they are the exception and not the rule where cruising is concerned.
Fact is cruising just does not work very well within schedule constraints and we have yet to meet a cruiser on a tight schedule that was a happy camper... It's always a compromise of sorts! Personally we are happier that we have arranged our life around sailing and quality of life rather than if we had continued doing the workaday world thing as being dictated by others...

It seems that it could be a relatively trivial modification to the
design to have the outer faces of these free flooding wells be bolt
fastened and removable. (Stoutly bolted, of course.) That would
allow an AS-29 to fit inside a standard shipping container. Indeed,
having the outer faces of the pivoting leeboard wells removable would
have an additional benefit of allowing access for maintenance.
The dog houses would also need to be bolt on assemblies, but that too
could be a relatively trivial modification.

I agree that this appears to be the heart of the issue, and it comes back to Phil's prioritization of parsimony in his design philosophy, a methodology we now see applied to nearly all modern, large cargo carriers. It takes a box to provide maximum internal usable volume, while accepting a small increase in hydrodynamic resistance. When mapped out on a logistic input/output curve, this design philosophy provides the greatest utility and functionality at the lowest cost and effort. It's what I call the 80% solution: mapped between values of 0 and 1, the greatest return on the least input comes in at about 0.8 (seehttp://en.wikipedia.org/wiki/Generalised_logistic_functionfor a short description).
I once heard Constant Camber described as the process of making your own plywood, at high expense and with the liberal use of epoxy. It does produce elegantly curved, strong, light weight hulls and certainly has its place. But I can appreciate that Phil would not be attracted to its use.

----- Original Message -----From:proaconstrictorSent:Tuesday, March 30, 2010 4:34 PMSubject:[bolger] Re: Bolger cruising trimaran?Mason, I always wanted to build a CC trimaran but it isn't as attractive with ply strips. If one goes to John Marples for the plans (as you know), he will give you a list of people who may supply the veneer. The venneer is still out there at a good price, judging by the price of plywood. I just could never find a supply for what I Wanted. Again, this could be one of those US vs Canada things, so people shouldn't rule it out in the US where there may be far more sources.
Also, on parts like amas, small cat hulls, most pro parts, everything pretty much except trimaran main hulls (and not over 40 feet as far as I am concerned) tortured ply or CM make better hulls, faster for a lot less money. Best thing about CC in my experience was how backyardable it was. Bust out the panels in the garage, and the assembly was really realistic in one's yard, something one can't say for a lot of techniques that need a roof overhead.
I love your CC boats, by the way.
One more note on Constant Camber-based designs.
Along with several multihull-designers using CC, Mason Smith has demonstrated successfully and, I gather, reasonably lucratively across dozens of his ADIRONDACK GOODBOAT, CC is a technology that has its place in the design and construction of various types of craft - mono- and multi-hull.
On the other hand, after lengthy reflection, observation, study of for instance cruising/racing multis, Phil did not like having shape and thus every other aspect of hull- and layout-design dictated by the inherently compromize-based shape of the 'master-panel':
- Many CC tris for instance end up quite deep and still are quite limited in 3+season live-aboard carrying capacity.
- Between shallower 'box'/other other ply-based hulls, hardchine, sturdy bottom, and the option to indulge in serious 'R' (or 'K') -value (to never have a condensation-drenched and eventually 'smelly' multi-season home), there is typically possible a happy confluence of various attributes from shallowest-draft per displacement, shallows board-up chine-sailing option, a serious 2nd if not 1st home (for what it might cost!) for various climates, and the option to add foam, ply, glass to nearly any level of impact-resistance for the unhappy encounters with inyielding things lurking out there.
- Furthermore, where lightest-weight for a pleasant shape - such as in a cartoppable GOODBOAT, or shells, etc., is not primary, the plywood-mill does a pretty good job of lamination the veneers in seconds, allowing us to focus our energies on the assembly of little pieces, bigger bulkheads ands full-length panels in likely shortest time amongs all comparable construction-methods, in part because of flat/gravity-assisted first if not final coatings (including glass on long, to-be-gently-curved panels), or same 'gravity-us-your-friend' approach but over simple flat-top sawhorses to build into the panel whatever curves you like, pre-curving and pre-finishing the piece for only modest adjustment and touch-ups once you hang the panel on the hull itself.
- Finally, one happy (and predictable) side-effect/opportunity inherent in ply-based/box-midsection-based thinking and building is that - whether plain sharpie or Vee-Nose sharpie hulls for mono or multi projects - you can fairly-readily add displacement amidships or aft under her bottom-'plate', not to mention hardening her belly on ballasted mono-hulls with a quite massive steel-shoe (or even serious cruising multi-hull via skinny plate ), or later remove a short curved say 8-foot length section of 'box'-hull and splice in the same curve but over longer station-spacing for say 12-feet module and a 4-foot net hull-length gain to add to displacement, or get shallower draft, and either way more accommodations volume and longer hull-length and thus a bit more hull-speed for pretty much the same input.
All in all, none of this is in the cards with CC the way we understand it... or most other approaches to designing-, building-, and living with hulls.

Proaconstrictor,
What are the good trimaran designs or elements that have either not been developed to their potential, or have been abandoned prematurely?
What do you find about the Hughes and Brown designs that are compelling for sizes which are appropriate for ocean cruising? Could you elaborate further about the SeaClipper and SeaRunner designs? What is obsolete about them, or what could be improved?
Why are trimarans now considered obsolete for ocean cruising? Is it just the whim of current fashion, or is there a more basic reason? If one were only interested in safe, long-distance cruising, not racing, could a trimaran be designed to carry a substantial load and still be weatherly?
What did you mean when you said that "Plywood is no longer really practical under 30 feet"? Did you mean 'over' 30 feet? Either way, I'm not sure where you are coming from.
And now to make a feeble attempt to bring this back to a Bolger topic, could a narrow, easy-to-build, Bolger square boat, but with a vee'd bow section, be used as the main hull for a trimaran? Possibly like the Schorpioen, but larger, and with no step in the hull for the amas to fit into?

I would add that one could probably get a darn fine plywood skiff or sharpie out of Dick Newick.
By the way, The Gougeons of WEST epoxy fame made some interesting fairly square trimarans with sharpie hulls in the early days, one of which was 35 feet and did the great circle route (Is that the inter-coastal/Mississippi route?). They built 2 24 footers, and for a client who was retired the 35 footer. This was near the very beginning of their careers. One of the boats was called Funky Tri, and is still in use in Florida today, last I heard.
JR Watson did a great little article on the boat a long while back, in Multihulls international.
Also, on parts like amas, small cat hulls, most pro parts, everything pretty much except trimaran main hulls (and not over 40 feet as far as I am concerned) tortured ply or CM make better hulls, faster for a lot less money.

I love your CC boats, by the way.
Having lived aboard full-time with Phil throughout 4-seasons incl. 5 winters in New England weather abord his/our RESOLUTION I do have a sense what even single-person sustainable life aboard might benefit from, whether in sweltering heat or being frozen-in solid in salt-water ice. But we never circled the globe of course...
Once going global is indeed firmly and doably on the table, then length-limitations should matter less and less, and real-world 3-4-season habitability should grow in relevance for de facto full-time living-aboard life-style. A longer lean simple-to-build/fast-to-build main-hull might be a sound basis for such plans - and their successful execution all the way to Trans-Pac jaunts or peering at the North-West Passage... Thus I'd venture investigating using a single hull of the DOUBLE EAGLE ("Great Sea") charter catamaran to develop a trimaran on. Without "Great Sea"'s additions and alterations throughout the project, that simple lean sturdy hull-design makes a sound basis for a very different overall geometry, with or without changes to her profile. Each hull is 40' x 4' with around 7000lbs displacement for structure, living-aboard amenities, and long-range provisions. The 'unfashionable-for-a-multihull' profile of D.E. came from single-level big-room accommodations with tankage and storage deep in each hull, fit for 6-pak charter or just longer-autonomy 1-2-some living aboard. The hull-design is thus suitable to start out with before adding wings & hulls to it. With berths fore and aft, single-level 'waking-hours' living could be quite comfortable, in stark contrast to the 24/7/365 sleek-racer school of design which typically suffers from mad man-hour bills for 'sculpting', dictate quite thin skins, are typically uninsulatable for 3+ season utility, and are often very sensitive to loading true live-aboard-plus-trans-atlantic attributes and supplies. 'Fashions' do indeed confuse many 'lists of priorities' from clients over designers and builders and finally literature on 'desirable' geometries. Since 40'x20'x6-berths and 6-person airy main cabin charter-boat DOUBLE EAGLE was built by one man in a longer narrow shop in at least three pieces (an heroic achievement if you let that sink in...), a tri should be doable in quite a bit less time, now taking advantage of lessons learned on our end.
Plywood/cold-molding is useable from shoulder-size 5'6" SHOEBOX, over 149-pac party-boats working from New England to Key West, to (for instance) U.S. Navy's 14-vessel AVENGER-class of 1300+tons displacement on 200+ feet length, active since 1987 in all global tactical and climate challenges from their Texas base to Japan and Bahrain, expected to work for at least 30 years in (most serious) naval duty... And unlike all petro-based/man-made materials, regrowable/domestically-sourceable wood and associated versions of it has not and might never suffer from the dramatic price-escalation that is inherent in all petro-based structural materials. Petro-based epoxy is by weight a defensible fraction of the conventional/or exotic GRP-approaches, even though by value it might at times rival the cost of domestic marine ply by the time you add cloth, tape etc on a larger project - your experience may vary of course. But when you embrace the comparative simplicity of one-off 'home-building' of sizeable structures such as TAHITI or DOUBLE EAGLE - without mold-building or cultivating the typically more challenging one-off all-synthetic approaches - you should be way ahead of any other construction-method. And plywood floats in any thickness. It may not be public information, but AVENGER-class's wood-volume might put her well on the way towards achieving 'sinking resistance' with a few more measures taken, such as via additional volumes of hard buoyancy.

The simple retracting mechanism for the floats and the main mast tabernacle could (should) be done with inexpensive hand winches. I found and exchanged emails with Ed Medalis who commissioned the design. As I recall he thinks he is to old to start the project now. He also wasn't enthusiastic about the punts hanging on the floats. I can't imagine a better place for them, but I'd probably tow a Fast Brick.
I could see doing the "Great Circle" of the Eastern 1/2 of the USA in such a boat, if one added fuel capacity (in the floats?) for the river and canal portions. One can partially or fully retract the floats for locks. I like the strong motor-sailer capability PB&F included in the design, and the extreme shoal draft. Depending on your point of view, they varied from or exceeded client specs with the big motor.
To build it, I'd start with the rig first, including the masts and sail. Then all the bolt on accessories, including cb, rudder, the arms that hold the floats, and brackets for the floats. I'd be tempted to over build those from steel, but maybe if I had a pro to the welding, I'd build from aluminum. Then the floats, and finally the main hull, which would be more complex than a Topaz but definitely in that family of designs.

The Seaclippers make sense, but could also use some updating which probably won't happen under current conditions. One of the issues is that in the sizes people currently want in these boats some kind of core construction is really required. Plywood is no longer really practical under 30 feet. In NA there really isn't a solution to compare with Duflex down under.

I would not touch any multihull he designed with a 10 foot pole. He just didn't get it, or alternatively was working in the dark zones. I mean there are things that multihulls can do that go largely unexplored. Both in terms of stuff one used to commonly see, out there, and stuff that is not commonly done. But in general I don't think he had an aptitude for it.
If I was looking for an ocean capable catamaran that was easy to build, and possibly cheap, I would look at Oram, or Kelsall. Kelsall is a genius and while I tend not to be drawn to his stuff, I know a number of very dialed in people who went to one of his seminars on KISS and came away sold. Oram is probably the best current value guy for large cats. For trimarans. I would build anything Kurt Hughes designed, or Brown if speed and/or cost were an issue.
Unfortunately with tris, nobody has really carried on the flame. There is an obvious need to get some decent boats in a simple format like stitch and glue, but nobody is doing it.
