    Little loops on the inside of the bows to set up a mooring bridle... https://photos.app.goo.gl/5nfmLVo9KU2Jk3oG8

    Tips for hiking on a feva?

    When I sail on boats for younger or shorter people (which I do a lot, play-racing with or against my 8yo son), I often use the opposite side hiking straps. Depends on boat and height...

    And therein lies the rub. This site isn't just full of trash. It has some of the best sailing know-how to be found online. Can we separate the gold from the trash?

    Whisper Foiling Catamaran Sailors

    As a minor note, the F101 and Whisper both come from the same builder -- WhiteFormulaUK. Fantastic folks. The boats have similar, perhaps identical foils with trailing wands.

    Whisper Foiling Catamaran Sailors

    That's a big big "it depends". Let me point out that monohull and "hiking" foilers are different, so the response below is about catamarans. In very light conditions, foilers lose to conventional boats because they don't foil, and they drag a lot more foil under water. In normal conditions, there's an inflection point where catamaran foilers gain big, with two caveats: tacks/gybes are hard, damn hard; upwind is hard, and some foilers just don't head upwind much so when you're getting into it, you just f up every tack/gybe, so you lose ground. And heading upwind involves mastering Veal heel, and sailing on the cusp of stalling the foils. In heavy conditions, it all depends on how crazy you are -- if you can keep control of the boat, and keep driving it... you're sailing high over the waves, until you're not ;-) As an amateur, it takes a time and a ton of work to master those parts -- I'm right in the process, and if I sail my Whisper against a conventional F18 I'll lose the race. I know Nacra 17 sailors who sail Whispers... who'd just blow past an F18, big time. But that's up to skill which I don't have. But! I don't care losing to an F18. When you sail the conventional F18 you're on the trapeze wire, you're doing what you'd do on a Hobie 16. When you foil on a Whisper, you're just in a different world. It moves, weaves in and out of the water. I've been sailing since I was 5 years old. This is just a different thing. Getting first to the finish line... one day I will. ~ With regards to hiking monohulls (F101, Moths, Wazsps, UFOs), they are a bit harder to get flying stable, but once you're there, they are comparatively easier to maneuver. Watch the videos where Nathan Outteridge shows a Moth gybe (or the recent video of Dave Clark gybing a UFO. You need 3 or 4 times more steps and coordination on a 2 person foiling catamaran.

    Whisper Foiling Catamaran Sailors

    Glad you enjoyed the videos! We just look pretty dorky tacking and gybing -- either in displacement mode, or in capsizing mode ;-) I am only now getting to the skill level where I would start to attempt foiling gybes. These have all the complexity of a 49er apparent wind gybe (see Bethwaite's book) plus the vertical forces from foiling. Charlie has posted a video of John Tomko (a pro/semipro sailor as I understand) performing a foiling gybe on his S9. Foiling tacks are usually 10x harder than gybes :-)

    I'm with @couchsurfer. You guys can pat each other in the back all you want. If you had young daughters, nieces, any young woman you care about in your life interested in sailing, and sailing well, you'd be ashamed to point them at interesting, relevant discussion threads in this forum. Was there an era in our culture that mixed sports with uncouth sexism? Yes there was. Those who enjoyed did not notice or chose not to notice that it was "fun for a few" and just plain horrible to a lot of people. You're one of the few that had fun? Now that you know it hurts others, at the very least it excludes them... how about let it go? My kid -- 8 yo boy, avid sailor, technically brilliant, helms an 18ft foiling catamaran at >15kt, loves geeking out on sailing topics -- ... and I won't show him SA. It has the brilliance of say, Steve Clark posting, and the complete shit of this thread. Head over to, I dunno, 4chan. Or separate them. Have a T&A forum, like politics has, or just

    @Dave Clark - I've edited your "light to moderate winds - straight leech" setup, and included it in the UFO notes google doc where folks collect notes. The paragraph above stood out... how do you achieve the twisted sail setup? (I have some ideas of how I think it'd be, but this rig is different than what I know so...)

    As a curious bystander, does this mean that the supply brouhaha is over?

    Added a "spare parts" section to the google doc, listing Mcmaster Carr and Amazon links to some useful & inexpensive spare/accessory parts I know of.

    Renting a RIB for Orange Bowl?

    The notice board where you'll find the most RIBs-for-rental listed is in US Sailing Center, by Kennedy Park. In CGSC there's a noticeboard near where the club optis are stored; by the evil robot-vacuum vending icecream machine...

    I can take a pic of the ribs on offer on local notice board a in coconut Grove. Send me a pm if interested.

    Also, rudder had a lot of slop, which I understand isn't normal. The bottom gudgeon had a plastic washer/guide placed atop the gudgeon. It'd work itself loose and ride up the pintle rod. Nothing would keep it in place, and once it rides up, the rudder is really loose. After we returned, I changed it to be inserted from the bottom of the gudgeon, so it's in a tight spot. Won't move from there and the rudder stock slop is gone. Not sure if it's right but it sure feels better than before. Picture of the spot after I had changed the plastic washer/guide to be under - https://photos.app.goo.gl/CKoSWtdaGWZQS9WX7 Hopefully it's clear, and I didn't mix up the rudder parts nomenclature.

    So Sat we sailed again, I followed the light wind setup to the T. Wind was marginal, around 6kt, but we got one gust and we flew with it. Sunday we had a bit more wind - 8-10kt - but I expected it to pick up to 15kt, so I wasn't thorough in tightening the battens. No flight :-( ... Once in the water we capsized to tighten them further but it's hard to know what you're doing, so it didn't get much better, and it was time to return anyway. Learned a few things.
