    Default Alpha Sabre - 3D performance

    Our 3D-printed IOM, Alpha Sabre, participated in its first club regatta yesterday, with Selwyn Holland at the helm.

    In the first race, Selwyn got a good start and led to the end. Here's a picture of our boat 167 heading for the finish line being chased by a Fusion and a Britpop.

    Racing was in B-rig conditions, and Alpha Sabre proved up to it. Nothing cracked, distorted, or pulled out...nice and rigid and no leaks. The boat handled beautifully, both upwind and down.

    There is no doubt that this technology is a viable alternative to other build methods.

    Certainly more interesting then footy or Nano.
    Can tell you more about the overall characteristics like DSPL, Hull draft, overall weight, Corrector weights, etc. Thanks !

    Claudio, canoe body depth is 60mm, total weight rigged is 4000g using 85g of corrector weight, max beam 147mm, hull thickness is .55mm.

    thanks, although 60mm depth is IMO too much !

    Why is that, Claudio? I think it's fairly common in the class.

    Generally a deeper hull will produce an hollow wave hence the increase of wave-making resistance.

    That may be, Claudio...but if it can compete successfully with Fusions and Britpops, I guess I might have gotten a couple of things right.

    Claudio, If Brad got some things wrong on Britpop, he sure has done a great job of fooling everyone for the last few years that it's been the boat to beat.

    The Britpop will always be a winner once in the hand of Brad.

    Brad can also beat the Britpop by sailing other boats.

    Brad has talent, gold fingers and the right sails...
