    Rogue Wave Trimaran

    And what of Gulf Streamer, the plastic version that rolled over?

    sail drives, worth the hassle?

    The Yanmar saildrives in my Saint Francis 44 were installed in South Africa in 1991. I bought the boat in 1997 and they were suffering some galvanic pitting. I cleaned them up and put fresh zincs on, they had been wearing stock, alloy, fixed blade props, I fitted bronze Martec folding props. Three years later the boat was pulled for a massive bow to stern rebuild. The engines were totally wasted so I did a very comprehensive overhaul - bored, new pistons, cranks, one camshaft, oil and water pumps etc, etc ,etc - read they had a LOT of hours on them. I pulled the saildrives all apart and the gear trains were in good shape but the alloy housing was bad. Figuring that alloy adjacent to bronze and stainless in brine with trace electrical current is doomed I set about insulating the alloy. Although the housing legs were well pitted it seemed to me that properly prepped the would hold an (insulating) epoxy barrier coating better than freshly cast and flash painted new ones. I replaced all the seals and fitted stainless folding props. I ALWAYS isolate the engine batteries when docked, I DON'T keep the boat on a marina and the zincs last three years, the legs look like new and the drives have run faultlessly. The precision drive train is way less maintenance and vibrates less than any of the shaft drive installations I have been involved with and with the folding props they are low drag for my SAILING catamaran that I like to SAIL!

    TS5 capsize

    So you hit something that causes rapid deceleration or change of heading and/or damage to hull(s) or appendages which leads to deceleration pitchpole or increased TWS due to that deceleration or different angular exposure due to directional change from the impact or lack of control from appendage damage etc,etc, etc. Not enough information on the incident to make any determination so it's all conjecture. Two reefs but how much foreword of the mast? The capsized shot shows some swell but how much and how long after the incident was that picture taken. Lack of underwater damage save the missing board and high freeboard indicating no hull punctures suggests she sailed over and 16 - 20 with a big reacher and a broach on a light boat might be enough. Conjecture on beam ratio/rig height without displacement or prismatic is grasping at straws too. That's a fine boat representing the current development of fast, fun, offshore cats so let's hope there are some lessons learned when more specific information emerges.

    Does that boat have escape hatches?

    Hydra Net vs 3Di

    That really is odd! I started SDI in 2004 as a consultancy/design resource primarily multihull related. In that time, of the boats equipped with HydraNet wardrobes, - Brown 34, Hughes 40, Burrage 40, Newick 35, two Farrier 39's, TRT 1200, Lady Hawk 37 and an Aerorigged Crowther 30 - not one of those sails has been replaced, few ever even repaired, whilst the laminates I specified for their perceived racing advantage, are mostly shot. In particular, the subject of this discussion is about to replace her second suit of laminates, which I had advised against, never having reached her performance potential with those often rebuilt sails. I well recall a very lengthy conversation with Tim Woodhouse, owner of Hood sails, who insisted that woven Spectra could never work - problem is HydraNet does work.

    MOD 70 vs. ORMA 60 - what's next?

    Tough to pitch pole upwind and the OSTAR was certainly influential on ORMA development - greater beam spells higher RM for a given weight and the 18 knot upwind @ 90 degree angle was real. Center hull length is somewhat irrelevant to diagonal stability in anything but mass. Square trimarans are more appropriate in smaller sizes, in bigger boats the increased mass delivers RM with relatively lower beam. So the boats can only be optimized for a given purpose - beyond the box rule - for ORMA I recall the limited sprit length and provision of an inboard engine were required after Olivier Moussy was lost in the Quebec- St Malo. The Race in 2000 saw no trimarans, all catamarans and probably represented their swansong in that down wind sleigh ride. Team Philips was the innovative member of that race but sadly never made the start due to a massive structural fail. ORMA was inshore, offshore, single, shorthanded and fully crewed and rhe boats delivered all round! French corporate spending and national pride had a huge influence on multihull development from 1966 to the present so what is the meal ticket for the future? My enjoyment and involvement lay in the private owner/builder era which involved smaller but equally exciting multihulls - will that path revive - probably not.

    MOD 70 vs. ORMA 60 - what's next?

    As I recall - please correct me if you remember otherwise - the Mod 70 was created in an effort to revive ORMA 60 which had run out of steam largely due to escalating costs and, from a spectators standpoint, the utter dominance of Frank Cammas turning the racing into a procession. Open classes yield much more rapid development, within simple constraints to discourage the dominence of size and money. The simple box rule of ORMA 60 did give us an era of truly amazing boats and sailers who greatly refined the art whilst pushing the envelope to their destruction - that Route du Rhum being a real wake up. On a few points - The 70 foot length was just a way to eliminate the sprit, same ama length. The curved, lifting, ama foil made for safer, short handed power reaching rather than placing more volume in the ama bows with the more destructive platform loading that creates. Everyone laughed at Geants stearing station windshields before she won, demonstrating the importance of preserving crew performance. The Route du Rhum disaster led to the control of the use of high modulus carbon with it's high cost and lack of shock absorbing toughness.

    Deal or no deal

    Building boats for a living is certainly not a good way to get rich unless you exploit cheap labor offshore and sell back into wealthier markets. Now that the US has elevated so many economies by this method at the expense of lost industries and skills domestically we may be approaching an era where it becomes cost/quality effective to drop the next (China, India, SE Asia) sweat shop and give our next generation a chance. Having purchasers of expensive imported goods be required to generate the funds necessary with their personal exported goods rather than adding to future generations debt would help. I bought a (used) South African build cruising cat only to find out just how bad a low skill labor build can get. After putting more time into making it the boat I thought I was buying than building a similar sized trimaran from scratch the lesson is well understood - there ain't no free lunch!

    I guess Chinese labor is real cheap still.

    Ditch the rig

    Nice - Catalina island?

    Ditch the rig

    Russel, how long are those hulls? What are they made of? What do they weigh? Do you wanna sell 'em?
  12. Where are the 50's and 40's going to be located?

    Broken Marstrom mast for free

    I would be happy to sell you a 30' chunk! You are correct that the low RM of the Outrigger 26 would not overload the section, but you should certainly make the rig rotating. The 34' overall would leave plenty after discarding the broken ends and making an internal splice for a 30' spar. PM me.
  14. All true, Laurent, but the diversity of the individual States of America is similar to that of Europe and the States that are generating the overall trend were, for the most part, late to the ball. Will Brazil overtake the US before the US overtakes Chile? It's a macabre contest which reveals the diversity of wealth, social responsibility, national authoritarianism and many diverse factors. Right now I am trying to understand to what degree the political venom seen in the US is a contributing negative factor
