    I have a 15' Supernova trimaran, built in Denmark in the 80's. Very nice boat: fast, light, cartoppable, can be launched singlehanded. Anybody out there has one?

    I need help

    I lost my trimarans tiller extension part.(the long aluminium pipe connected to the rudder head and tiller. I am trying to manufacture one but not sure about the dimensions and the angles and photos ,could some body send me these details?Please I need a supernova owner who will help me. my email adress is ozgur@mercan.net
    Thanks a million.

    My boat ist stored in my beach house, about 60 km from where I live.
    Pity because I was there last saturday and if I knew I would have takem measurements and photos. I'll do that next time I go there, but you'd better keep reminding me at my email: pippobianco"at"alice"dot"it

    I live in Auckland New Zealand and I have one of these supernova Tri marans. It is a very quick boat and have a lot to learn about its characteristics. The last time me and one other took it out in about 20to 25 knots and it just flew across the water with a roostertail wake behind it. We were sailing along just fine on the edge when one of the support brackets broke and we ended up cartwheeling the boat. With wave and wind buffeting us as we laid dead in the water the alluminium frame started to crack and then broke at the mast step. I intend fixing it but alloy is so difficult to weld properly. Any ideas on how to fix this so that has less chance of re braking

    I have sailed the boat in 25 K and I had to depower the jib several times because we were about to take off :cool: Anyway, IMHO the Supernova has to be sailed flat because the amas cannot support much load.
    The only possible solution to repair without welding I can think about is a sleeve like the one used in the mast...

    Thankyou for your reply. Having seen the photos of your boat it looks as if you have had strengthen your mast step area as well. I will endevour to make something similar.

    Hello - here are the measurements (I also replied on your email address).
    The two halves of the tiller extension are 159 cm each (from the tip to the central hole); the rubber grips are 24 cm long. The angle is 8,3 degrees (I computed it with a little trigonometry): in fact if you put both ends against a straight edge, the central hole is 23 cm above that line. The diameter of the handles is 1,5 cm. I've also taken a couple of photos: if you need them, as well as a drawing, just let me know. :cool:

    dagger board

    Hi I lost the dagger board to the supernova tri while moving could somebody send me the details/picture/dimensions of one.
    Thank you

    Do you still need this ? - I can send you one - but I have a bigger problem, my supernova took off a few weeks ago in a storm and cartwheeled - the mast has a gentle curve and not repairable (apparently) - does anyone have a mast they can let me have for a reasonable price ? Otherwise I have *alot* of spare supernova parts, starting with the hull...

    I would have thought pretty much any beachcat mast would do as the section is very light even a dinghy may be able to provide a suitable replacement. It's just a round section IIRC

    If I were you I'd check out local mast suppliers and see how much they want for a similar replacement section and transfer your hardware.

    I really enjoyed sailing my Supernova (now sold to my dad) it's a balanced boat which is not overpowered however it would really benefit though from a proper daggerboard rather than a flat plate centerboard and the main hull is a bit heavy. I've often considered flopping a mold off the main hull and building one in a lightweight polyester foam sandwich it would make it a better boat if a little more prone to damage. I'd get rid of the heavy and unnecessary cockpit at the same time.

    Having said all that the Ibs Por Nielsen did a great job getting the boat into production even if it is a little compromised in some ways and the rooftopping and demounting system is quite ingenious.

    About masts..Thanks Corley

    Thanks Corley, I thought it could take months to get a response - amazing :) Ive had a mast and rigging specialist look at the mast, and it seems to be very solidly built - perhaps overengineered - the rigger tells me that this needed strength is due to the rigging arrangement - as the stays stop 2/3s up the mast effectively a third of the mast is unsupported - however having said that I could take a gamble and just get a modern mast and design a new rigging arrangement - the main is after all not deep. If you have any thoughts on that do let me know !

    The factory mast is In my view not a heavy section by beach cat standards and bent masts on Supernova's are not all that uncommon. If I was to put another mast on I'd look at something from a 16' beach cat with trapeze as the boat can take a bit more power and sail area, if you were singlehanding you could even use a trapeze if the wind was up.

    I tried my boat with a mast and sails from a Mk2 Mosquito catamaran which I happened to have at the time and it was fun and still quite manageable. The mast I used was filled with foam but I never got to test it as I never capsized the boat it would be worth doing a capsize drill with some help nearby to see that you could right the boat. The interesting thing was from my observation that the jib from the mosquito was more effective on the supernova better forestay tension I guess than the bridle on the mozzie provided.

    The Supernova's reasonably wide so you have a bit of righting moment to play with even with the tiny floats. The cool thing about these boats is how forgiving they are you can drive those little floats under without capsizing the boat. I've heard that you can pull the tramp spigots out of the hull flange when sailing but never experienced that fault personally even with the bigger rig.

    If you wanted to use the existing Supernova sails just cut down the length a bit.
