    Vector rudder upgrade

    One nuance that's being at least partially missed here is that these upgrades are both done on existing boats. A q28 in short order and an MC38 with some care have been radically turboed. It's work but if you look at the accumulated hours in incrementally upgrading Wild Oats XI vs the total rebuild of the mule, it's not so different. We're looking at a AC rule that might well lead to a pile of revolutionary upgrades to boats like IMOCAs V65s and even billion dollar pigs like maxi boats. You could go back and make Commanche competitive for outright records, rather than outright "monohulls only" records. If you already love maxis and ocean racing monohulls, you won't see that as a big deal, but if you're confused by the ongoing presence of monohulls at that scale, like I am, this is a serious development.

    C-Class Little Cup news

    Fun architecture. We do mostly the same thing on the UFO. One note: I have yet to see a c-class that wasn't bolted together. Co-curing or post curing all at once would be amazing to pull off purely as a technical feat but I don't know of any boat that was done that way. Before you progress much further with your project it would probably help to pick the brain of somebody who's built an ok one. That always helps flesh out configuration concepts. DRC

    Steve and Dave Clarks Unidentified Foiling Object

    From this weekend. Reject weakness. Sail boats that are as tough as you are. There was a laser out there too when the breeze was a bit lighter but its mast snapped. 35 knots (40mph) in most puffs 27 knots (32 mph) in the quieter lulls. 50 knot waterspout missed us by less than a quarter mile. Unsailable conditions are a hoax. DRC

    Modest website update. More to come in the coming months, including an owners area http://www.fulcrumspeedworks.com/UFO/ DRC

    what is it?

    Way heavier and higher horsepower than a pushrod and a flap.

    Exciting High School Sailing Dinghy

    It doesn't need to be more expensive to be better. There's a concept among manufacturers that to continue up the hierarchy of technology one must progress up the hierarchy of prices. Product design follows accordingly. It does not need to be that way and until we've solved the attrition problem in this sport, it's not justified to support that hierarchy. To that point, Mustang_1, mylar is cheaper than dacron. I know because we made the UFO sail out of Mylar because it's cheaper than dacron. Laminated film is WAY easier to make than woven dacron. If there was cheaper cloth worth making sails out of it, I would have bought it. Speaking of attrition, I left highschool sailing after freshman year because the 420 and FJ were slow and unresponsive. I loved my team and my coaches were good. I was already sailing skiffs and the boat was like going from a car back to a go-kart. It was entirely unresponsive to the skills I'd developed in skiffs and ICs. I was 16th in the world in the IC. I had to go back to the start and figure out how to make a stone age boat go 5 upwind. Like going from indoor plumbing to digging a latrine. What the conventional college dinghy like the C420 without any of the fun parts or the FJ or the firefly or the lark or the tech dinghy do that's excellent is that they're quite solid in no wind, which is a common condition. This means they're able to do a bunch of races in a row in light air and are able to deliver results for teams. That feature can be held through on other designs, it just isn't done. Probably not a bad design brief. One other note: i14's and ICs team race at their world championships and AC50s match race. You don't need to be slow or old school to use the rules. One final note: I'm not saying "we should all switch to (insert existing product)" because I'm certain that no such product that does the job in this brief presently exists. But it could. One note beyond the final note: I didn't rejoin scholastic sailing for college because I'd already switched to pulling oars which without question rewarded me for stepping up to another degree of technique and athleticism whenever(rarely) I achieved that.

    Photo of the weekend from the Annapolis demo day 3. Rob Deane, director of Baltimore County Community Sailing Center kicks it along down wind in a 10 knot puff. Day 4 featured about 19 knots gusting 30. Sufficient de-powering turned it into a 15 knot day. Definitely moded for the puffs, though. DRC

    Superglue in the case of that tiny piece of flange. That part of the plug is entirely cosmetic, as it is passing over solid aluminum. In practice on my own personal ufo, when that "tail" popped up I trimmed it with a razor blade. DRC

    As you're doing your pre landing approach get going at about 2 knots plus in a direction, any direction, with the rudder halyard fully loose. Wiggle the tiller side to side within about 20 degrees of total range. This unloads the rudder from one side of the plates onto the other and as it passes through the neutral point between these loadings will be extra likely to climb. Also have a decent amount of rudder positive lift on. If you have the nylon rudderhead brake, you'll automatically save this progress. Once it's at a height you're comfortable with but can still steer with, cleat off the halyard and proceed to shore. DRC

    order!? Aw 'cmon! We're going to compression mold them from clearcoated carbon fiber DRC

    Martin, Epic footage! One piece of advice: put ale on the stick and take over as crew. The boat is mainsheet driven so the kid position is tiller. I mainly say "steer, but please please keep it on a straight line" DRC

    Suuuuper high grady polycarbonate. The Methylmethakrylate etches into the epoxy and the polycarbonate and makes a seriously impressive adhesive joint. DRC

    It's pretty hard to find in small quantities. It's a silver bullet for us from a production standpoint. Meanwhile, there's a new short in the show don't tell series. This time answering the perennial question "can you right it from a turtle?" DRC
