    Extreme Sailing Series DTS

    I watched more ESS when they used the X40, switching to the GC32 made the series lose it's uniqueness. I'm sure that's not the only reason that the series folded but it may well be a contributing factor. The stadium sailing format while it led to some rather tedious races at times in certain locations brought the boats close to the crowds.

    Quite a few differences between Bullfrog and Ave Gitana, Ave is a mix of materials in construction. Strip plank WRC main hull, durakore floats and foam beams as I understand it. Somewhat heavier than Bullfrog and a little more cruising oriented I think she also had a bit more beam in the main hull. Ave is now a little longer after having a carbon fibre hull extension added. Bullfrog was WRC below the waterline and strip plank balsa above and balsa strip plank beams. Ian mentioned to me that Bullfrog weighed 2000kg when she was first launched with Cat1 configuration gear loaded, not sure how that changed with rebuild into Aero and later rig etc.

    Tremolino trimaran.

    The dilemma is though would you build such an old design as a Trem from scratch now? You could easily build one of Kurt Hughes 23' tube crossbeam trimarans or a Strike trimaran from Richard Woods if you were after something a bit smaller that used beach cat floats.

    Spindrift 2 Jules Verne 2018

    According to Marine Traffic AIS, Spindrift 2 is just off the Port of Fremantle now:

    Tremolino trimaran.

    Pat Newick still has complete plans available that include all the different versions of the Tremolino for $400 USD I believe it was when I checked. The build looks simple, the original John Olin style main hull is stringer frame. The later new moon type floats give a lot more volume to the floats but the original style boat with the Hobie 16 hulls as floats works well. It's not a powered up platform but it's still very pleasant when sailed within its limits. I'm not exactly sure how much the main hull weighs I'll have to put mine over the scales one day but I easily lifted it off onto furniture castors one end at a time by hand by myself from the trailer.

    What is it?

    The trimaran hanging from the rafters is the ill fated Oman Sail trimaran Majan which had a beam failure in the 2010 Route du Rhum. Sidney Gavignet was forced to abandon the boat. Since then Marc Thiercelin has attempted to raise the money to repair the boat and get it ready to race again.

    Hull Dollies

    Thanks, I'm pretty happy with it. If the amount of good and fun experiences could be quantified to hull weight this boat has been completely amazing. Should be a bit nicer after it's rebuild.

    Hull Dollies

    I built some simple hull dollies for my Trem using furniture dollies as a base. The side cheeks were just tongue and groove boards which I had lying about with plywood gussets. I flirted with the idea of getting fancy with a high density pour foam but the Trem is flat bottomed so no real advantage in my case.

    Multi 50 specs/payload

    Well motions should be somewhat more gentle with the smaller floats. 300% floats on a square platform make for a very stiff boat that takes quite a beating in a seaway but the performance is better and they are faster because it will stand up to their rig with less heel. I'd guess the older Multi50's look like they have something like 200% floats, I'm not sure that adds up to less stress on beams as the extra float immersion of the smaller floats can bring its own stresses to the structure. A careful survey by an expert surveyor is of course the only way to be sure but I'd prefer the older and less extreme trimarans for conversion to cruising and they still wouldn't be slow. Good boats are out there, Chris for example who bought the 40'er racing trimaran Star of Trinite (now named The Edge) has had a good experience with his boat although it's not really been converted to a cruiser and is still a racer.

    Multi 50 specs/payload

    In some ways the earlier Multi50's might make a nicer basis for a conversion. Generally smaller floats that don't work so hard in a seaway, plenty available but you need to examine them carefully to see if they are worthwhile as far as a refit goes. Limited payload of course but no reason you can't make that work if you are happy with minimalist fitout.
  11. Just out of interest is a ply Tornado still competitive with the later Tornado designs if it ran a modern rig? I'm not saying front of fleet performance but how far would one be off the pace?
  12. I have a "box" rule governing the design it has to fit into a 40' high cube container with all the bits in there beams floats, main hull and mast it's a tight fit.
  13. Square racing trimarans are not unusual in smaller sizes. For example the latest Multi50 design by VPLP:
  14. Mast is about 19.3m iirc, Yes all laminates to be done under vacuum, no layup schedule as yet for main hull. Hesitation on float materials is mainly to do with the cost 2 layers of ply in cylinder mold plus core for panel stiffness. If you use decent ply (and it seems crazy not to in this context) it seems that it is pretty comparable price wise with using foam core and foam does better in impact and is a bit lighter, when the schedule is finalised will review relative cost. I do like the idea of cylinder mold in that you create a lot of hull in a short timeframe with a minimum of mold construction but I'm a bit concerned if things go badly you could lose a lot of material too. I bought plans for one of Kurt's daysailor designs and bagged up some layers of cheap ply over a partial mold using the shop vac to get a feel for the method and it did work quite well. Foam sandwich however allows for a more rounded sheer on the floats which is more visually pleasing and allows more freedom in terms of the shape. The plan is to weigh each component to see that no extra weight creeps in during the build process and also to get professional boat builder help for the laminate work and vacuum bag setup as I don't feel confident in that part of the work. Most larger trimarans I've seen launched end up heavier than their design weight, Andy seems to be doing pretty well on his Shuttleworth racing trimaran project so there is reason to hope we can meet our weight targets. Top speed of Kurt's previous F40 trimaran was 25 knots. I'd imagine this would be similar.
  15. Well I'm not ancient yet but yes I'm 42 now so the prospect of having to bend double going into the cabin and crawling around in the hull is less appealing, maybe it has less to do with age and more to do with wanting a fraction more comfort. Famuu Sami was built too heavy but having spoken to the current owner he is very happy with the boat and also owns a 63' Kurt Hughes trimaran Rozinante, that I think speaks to it being a good boat even though it could have been better if it met its weight targets. I've spoken to a number of Kurt's builders and most have been very happy with the results of their build and the lightship weights achieved. On the budget front, we all have different ideas of what the word means I believe that I've crossed my t's and dotted my i's in examining the costs of building the platform and speaking to other builders and their tallied up costs I think it's close to accurate, not cheap but affordable if spread out over time.
