    Route du Rhum 2018

    It’s one of those races so which does allow quite a bit of outside assistance. Remember those reports (from the Multi 50 but was similar with Amel on BP before) who took a pitstop, the skipper was sent to sleep while a big shorteam worked on the boats for hours, fixing smaller and bigger problems, before sending the boats out again?

    this starts to remind me of some VOR finishes

    what’s the distance between them and how far to the finish?

    A Class Worlds - Classic Division

    Thanks madboutscats! Interesting to hear! Unfortunately my last A-cat was a Flyer 1st gen. and I left the class before the canted boards (and the C boards and nowadays variations) emerged, so never saw the difference. Anybody else here remembering a similar experience, that canting symmetrical straight boards is not making a noticeable difference over a range of conditions? Thx!

    A Class Worlds - Classic Division

    Hi folks, I am considering doing some work on the daggerboard cases on an older 25 feet catamaran (KL25). Some people suggested I should cant them then too. The boards are symmetrical, actually from the Ventilo M2. Does any one here recall from the times the A-cats went through this change as well and could share his knowledge? Is there really any noticeable benefit in canting a straight symmetrical board and would those benefits be more noticeable upwind or downwind? I am considering canting the boards inwards by some 15-18 degrees and someone more knowledgeable person than me suggested to also toe in by 1 degree. Is this all worth it? Thx!

    Bora gulari nacra 17 incident

    sheet wrapping habit: I sail with a variety of people and always try to encourage everyone to avoid the rather common habit to wrap a sheet around a hand. I encountered a dismasting once while double trapezing and sadly my crew had the jib sheet wrapped around his hand, which then became his sole support. His hand was never the same after unfortunately. My advice would be if you need to wrap the sheet to deploy more force and a better grip, unwrap it once the adjustment is done. A broken trapeze line or harness failure can produce the same result as a collapsing mast for the scenario described. Anyhow, wish everyone a safe and fun sailing year 2018!

    A Cat Worlds Sopot

    So if there is no further race today, then this was the WC and yesterday's overall results are the final, correct?

    anyone has a link to a video from yesterday's racing?

    Not sure where you guys find the best info? It seems the facebook page from the International A-Division Catamaran Association is doing a decent job in posting updates like daily reports and photo galleries. The Polish people were doing some nice videos on Vimeo before, but not sure where to find them? http://www.a-cat.org/?q=node%2F1045&utm_source=dlvr.it&utm_medium=facebook Seemingly it wasn't the capsize which did cost Hemskerk a good finish position, but rather a miscounting of the number of laps he had sailed.

    All about numbers? Who do you trust??
  13. Hi Jim, thanks for the feedback. I actually did consider adding foam as you describe and actually have done something similar to one of my boats in the past with some success, but it does come with a weight penalty, I am not too fond off, considering how much I would have to add at the transom to get it anywhere near to my liking. Currently the boat is 7.65m long but the depth of the rocker is 35 cm and I think something like half of that would be far better to reduce pitching.

    Oracle Team USA

    Has anyone else here read Bruce Knecht's "The Comeback" in which the author described how Oracle started to use the grinders to constantly pump their mainsail and claims that it was this newly learned skills which in combination of some other mods to the foot of their wingsail, an increased rotation of their wing and changes to their rudder elevators enabled them to become the faster boat? It sounded plausible if true.
  15. wondering if anyone ever has done this and what would be the easiest method to reduce a too pronounced rocker (causing a lot of pitching and hobby horsing) in an old V-shape/U-shape like glass polyester sandwich hull construction? hulls in question are 25 feet long and only feature one bulkhead under the front beam, which will require adjustment. a first approach is thinking to reduce the rocker by cutting out a up to 20cm wide section (as it widest point near the daggerboard trunks, reduced to 0 when nearing bow and stern) along the centreline. In a next step to cut/mill the outer skin in several staggered longitudinal lines along the previous waterline and the new centereline. the purpose of this is to then allow bending the otherwise stiff sandwich laminates towards each other until they meet in the center, hereby reducing the rocker (and volume) of the hulls. the idea is then to join them in centerline again and to fill the cuts in the outer skin with lightweight filler and add one or two fiber layers on top to the same thickness as the outer skin which was cut. another approach would be to cut the hulls off below the waterline, build a complete new underwater section, and to join them together again. I would assume that the first approach is faster and less costly then the 2nd, however I am not sure how well it will actually work to bend an already built sandwich construction just by cutting a few cuts in the outer skin, so would appreciate anyone familiar with catamaran hulls as such and the proposed measure to comment on it. I am aware that both measures will reduce the volume of the hulls and as such will affect how the hulls sit in the water (lower) but believe that the hulls carry enough extra buoyancy to allow such measures. I am seeking technical advise/ shared experience rather than opinions or debates of why to do something radical like this. many thanks in advance!
