    World Sailing Vote ... Proposal M36

    If the editorial on the front page is to be believed, the finn is in and the Europe Dinghy is back after a super long hiatus. woo.... DRC

    Steve and Dave Clarks Unidentified Foiling Object

    We've got two demo boats and a RIB down at sail newport from now till the end of the VOR stopover. Book a demo on https://ufodemo.com/ You'll be able to see us anywhere. We have https://ufodemo.com/ printed in giant black letters on the sails. From there you can book a demo from your phone on https://ufodemo.com/ and we'll be able to get you on the boat easily. If you can't tell, I'm kinda excited about https://ufodemo.com/! It puts you automatically into a booking spreadsheet on our phones! #automation! DRC

    Focus on knowing the lull is coming and doing everything to glide through it. Moving your bodyweight will often be too little too late. I find that sheeting in, bearing up or off to a dead even reach and even pumping are the three tools to get through a nasty lull. If you're out of it and rolling into weather, I actually deliberately jam my lifejacket into the water to arrest the roll. DRC

    That's definitely stray g-flex in the flap. Upgrading to a vacuum bagged hinge glueing process had some unintended side effects which we didn't instantly catch. We now have pieces of molded silicone which arrest unintended glue travel. Sanding out any stray yellow glue will restore it to normal function. I strongly advise against pulling out any of the sika in the hinge. The foil is driven by and benefits from twist. Requiring firm pressure to actuate it keeps the noise out of the system and firm downward response keeps the boat safe in chop and gusts. Reducing the foils capacity to pull down in tough spots will make the boat a dicier ride. You won't notice it in ideal conditions, but you will in tough stuff. Pulling the wand out entirely yields a tiny marginal improvement in speed in light air, so I doubt leaving the wand in but reducing the force requirements of the system will make the boat foil sooner. I'll shoot a video on launching and landing technique today or tomorrow. To everyone out there, please PLEASE don't go drilling holes in your boats. Holes cannot be undrilled and the answer has far more to do with technique than technology. DRC

    I often bear off a tiny bit until I'm situated. Sailing out of your puff can do it as well. Over-sheeting can also do it. There's a difference between pumping hard and stalling out the rig, which can be learned iteratively. Additionally, trying to dial in too much weather heel can do it. There can easily be too much of a good thing and in moderate puffy breeze I still on occasion succumb to too much roll on the takeoff, where I find my self scrambling into the boat and reaching for the shroud as the boat skitters along with the weather hull in the water, heeled 45 degrees to weather. If you can get a goro on your wand sprit facing aft, I bet myself and a lot of people on this forum can help. DRC

    We now use a nylon thunbscew threaded into the cheek plate on the rudderhead. Email us if you want one in the mail. That bug should have been squashed a year ago. DRC

    Two turns more to the right on rudder. Though if you're on anything aft of the center on the mainfoil, returning the mainfoil to center would be the best first step. DRC

    We just started integrating nylon thumb screws threaded into the cheek plate of the rudderhead. I'm still not in love with it, but it does improve things. I took forever trying to find the perfect nylon wingbolt and just spun my wheels for about a year on it. Gave up and went for a knurled head. It does work, though. DRC

    Building a Foiling Beach Catamaran

    If he's this bad at trolling, imagine how bad he must be at sailing or building. Re: the actual question for anybody who's considering such a project. If you have a 4800 square foot fully equipped prototyping shop at your disposal, a deep stack of existing tooling, a deep stack of various rigs, sails, fittings and hardware, good design software, 20 years of intermittent building experience and a couple NAs and engineers available to bounce ideas off of, you should be able to make a small working prototype in about 540 caffeinated man-hours. That's about how long the "Probe" UFO prototype took. Then expect to spend about a month of time on the water tuning it up. If you have all of these things at your disposal, you can avoid spending currency, but you will spend all of the above. Essentially, paying money is the cheap way to get something. DRC

    I'll make a note to talk to gowrie. They insure Fulcrum on a number of fronts so they totally have a dog in this fight: us! DRC

    I was about to expound on this last night but stopped myself and made a VIDEO TUTORIAL instead! Disclaimer, I did not script this and I mumble and misspeak a couple times. However, I still think it will help. DRC

    Sadly, there is but one Gary Baijent design for every 1,000 bland, cowardly, and derivative designs. DRC
