    Corsair Pulse 600

    I am looking at my GPS trace and too embarassed to post it here. When I have time I will try to sail the same course low and fast or high and slow and compare the GPS traces to try and work out something on my own, but I am interested on what the consensus is in the Pulse class, alternatively, I am also interested in witnessing a good shit slinging from a safe distance.

    Corsair Pulse 600

    hello Pulse sailors I have just started sailing my boat, and the Pulse is probably the closest widespread design out there so I am looking for your pointers on sailing upwind. So far I have sailed twice in winds gusting to maybe 10-12kts max, and what felt right upwind was boat speed 7 to 8 kts but then looking at my data, my tacking angles are around 100°. Bearing away just a touch I can easily touch 9 to 10kts boat speed but this feels more like a close reach than sailing upwind. I am an experienced sportsboat sailor, but new to the world of multis, so interested in your experience.

    for some unknown reason, I think this is my favorite thread on the whole SA forums

    DAGGERBOARD AND RUDDER CORE

    think of your boards as I-beams working in bending, you have your flanges (skins) working one side in tension, the other in compression, and to link the two, you need a web (stock) which will be working in shear. on very small boats the shear strength of a foam core may be sufficient to handle the shear force but on a 26' you definitely need a proper shear web. try to copy what has been done and tested on similar boats, or talk to a designer/engineer.

    max clew load - f31r

    hi Vincent some numbers off projects I worked on: Corsair 31: leech load 980kg Corsair cruze 970 (heavy mf): leech load 1200kg F-33R : leech load 850kg these are all for max RM full main and jib, but really your boom designer should work the leech load out. If not, what is he designing to ?

    Hi RV I am seeing the light at the end of the tunnel. One problem though, I have an old dacron main from the donor cat, but it seems to have too much luff round for my stiff carbon mast. Please PM me if your Kevlar main is still for sale. I am in Sarzeau for a couple of weeks.

    NBA Playoffs

    Based in France, and visiting NYC at the end of October. I am considering going to either a Knicks or Nets game. I see the schedule just came out, Nets tickets are already available via ticketmaster and Knicks tickets available tomorrow. What should I do, buy them now or wait and buy later on seatgeek ?

    Carnage at the Bol D'Or

    It is known in the class that you ABSOLUTELY have to loosen the backstay and vang at the top mark before bearing away and hoisting the kite on a GS in stronger breeze. I think the mast is probably a little under spec'ed

    I'd be afraid to accidentally lose a testicle sitting on the floor so close to where the boat folds.

    hi RV, looking good ! no recent pictures of mine, but the main hull is all primed up and should go into painting this week. Now the fun of putting things together starts ! looking forward to sailing together in the most beautiful sailing spot there is: the golfe du Morbihan.

    Sun Fast 3300

    you can find them on: https://evenements.ouest-france.fr/spi/resultats-spi-ouest-france-2019/ select "SPI OUEST FRANCE 2019" then "valider" in "résultats généraux" select "IRC DOUBLE" The 3300 is Sapristi in second place behind a JPK1080. Leon, the JPK1030 has done pretty bad, but I don't have any gossip as to why. The J/99 is third

    @MultiThom In my case choices are made easier because I am working off an F18 cat so a lot of these choices are already made. I have chosen to line up the transoms of the floats and main hull (which is a touch longer), and my beam positions are fixed by the mouldings on the floats. For simplicity I wanted to have the mast on the forward beam. Rudders come from the cat so that's one choice less to make There are rules of thumb for centre of lateral resistance position relative to centre of effort of sails, but they really apply to monohulls which heel. I have studied a couple of trimaran designs of which drawings are available online, and from my job I have access to a lot of sailplan drawings, some of them also showing CLR position. Put all this together and came out with a compromise. However, I have allowed for a few degrees of centerboard rake fore/aft, and the mast rake can also be adjusted if necessary.

    cool building process and I like your boats, but you still need a mould right ? I went for plywood sharpie construction because I wanted to go stitch-n-glue. I'm on a budget (not paying for the carbon bits )

    @Vantage475T thanks ! the concept is to use as many parts as possible from the donor F18 cat, so the mainsail is an original dacron main from the late 90's, with small flat top. The class F18 jib at 4m2 is too small and not the right shape, so I am having a 7m2 jib built. For now I will use the F18 21m2 spinnaker and I have a 16m2 code 0 from a previous boat that will fit nicely. The first upgrades will be a more up to date F18 mainsail, and probably a bigger spinnaker. I work from a 3d model of the full boat so I don't really have 2d drawings to show. I think it is a good concept, there are loads of Alado 18 / Hobie Tigers out there, so if enough people show interest, maybe I will stop procrastinating and actually put some 2D drawings together or why not a set of construction plans.
