    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 !

    Gio,
    my first post/remark to Bill was referred to the 60mm draft, nothing else.
    Then came up the name of Brad and my comment was simply recalling his talent as designer and skipper including Sail making.
    I have nothing to adds !

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

    So then, Claudio, how would you explain the success of his M and 10R designs? Just his sailing skills?

    Yesterday, Selwyn took Sabre up to Kogorah for a regatta.

    He said, "Mate it was amazing. All the fast IOM guys in Sydney were there plus three from our club. Multiple national title holder (8th in the recent worlds). 12 boats, variable conditions." Sabre took two firsts and one second of seven races.

    Here is a link to a video from one of Selwyn's club races https://www.youtube.com/watch?v=fd1oC4CxESM.

    The pink boat is a Britpop sailed by Lynn Kreibig and the green 167 is Selwyn.

    As a complete non-racer (non anything really) I thoroughly enjoy the banter with my popcorn - One also learns quite a bit

    Are you designing hulls with 3d printers in mind, or is it more a case of Selwyn finding the settings that work for "traditionally" designed hulls?
    I think what I'm trying to ask is - have you changed your design ideas based on feedback from Selwyn? Adapting designs that make the 3d printed boat better that wouldn't necessarily make sense with a normal layup?

    thanks, although 60mm depth is IMO too much !

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

    Are there other designers that you respect, Claudio?
