      Abbreviated rules   07/28/2017

      Underdawg did an excellent job of explaining the rules.  Here's the simplified version: Don't insinuate Pedo.  Warning and or timeout for a first offense.  PermaFlick for any subsequent offenses Don't out members.  See above for penalties.  Caveat:  if you have ever used your own real name or personal information here on the forums since, like, ever - it doesn't count and you are fair game. If you see spam posts, report it to the mods.  We do not hang out in every thread 24/7 If you see any of the above, report it to the mods by hitting the Report button in the offending post.   We do not take action for foul language, off-subject content, or abusive behavior unless it escalates to persistent stalking.  There may be times that we might warn someone or flick someone for something particularly egregious.  There is no standard, we will know it when we see it.  If you continually report things that do not fall into rules #1 or 2 above, you may very well get a timeout yourself for annoying the Mods with repeated whining.  Use your best judgement. Warnings, timeouts, suspensions and flicks are arbitrary and capricious.  Deal with it.  Welcome to anarchy.   If you are a newbie, there are unwritten rules to adhere to.  They will be explained to you soon enough.

    Tom, can you just slide the akas out of the sockets and then turn the main hull on its side or upside down and insert the board to look at twist angles and cant? Thats what I do with both my boats, and they're much bigger.
  2. Home Built 18' Trimaran (based on Scarab 18)

    Nice! That's a good idea too! I was close to an hour from trailer to water previously, I want to get down in the 15-30 range myself. Down here in TX you melt if it takes too long! I have carbon inside carbon tubes, but with a lot more gap. I think thick UHMW tape at 9, 12, 3, and 6 will do the trick for me.
  3. Home Built 18' Trimaran (based on Scarab 18)

    Jetboy, I was searching for my own build but thought I'd share some resources I found for UHMW tape for those sliders, t least once you get them milled or order smaller OD sections. Tape thickness ranges from .03" to .12", or 3 mils to 125 mils. http://catalog.cshyde.com/viewitems/ategories-tapes-with-adhesive-uhmw-tapes-1/uhmw-tape-acrylic-adhesive https://www.findtape.com/film-tape/uhmw-skived-teflon-tape/c124/ http://www.eplastics.com/slick_strips
  4. which multihull jib ?

    Hey French, I have built 2 tri's, a 23 footer using a Nacra 6.0 and a 20 footer using an A-cat. Both boats I had to get custom furling jibs made for precisely that reason. Attaching the jib tack to a dolphin striker on a cat is always higher than a center hull on a tri. Not very compatible with trimaran dimensions. I used Skip Eliot of EP sails in Costa Mesa, CA. He is easy to work with and charges reasonable rates for very good sails. I use technora-flex material in a crosscut style, which is perfectly sufficient for boats this size, tri-radial carbon or string 3D is overkill. About $600 for the custom jib.
  5. Astus 16.5 sails... finally!

    Hey Tom, glad to see it almost ready to use! You've done an amazing job. Would you be willing to postal few photos of the sliding mechanism/shims/uhmw pieces please? I am re-building a boat with a sliding mechanism, and I want to improve it. Before re-build it worked alright, but certainly not the smooth and quick I was looking for. Basically I have a tube within a tube, with the inner tube wrapped in u how tape. Can you describe how the Astus slider works and pots a few photos please? I've never had the opportunity to see one up close and examine. Thanks and Merry Christmas, Adventure Tri (Mark)
  6. I demand an answer!

    In 10knots and flat water Osprey Is tacking through 90 and staring to come alive, probably doing 9-10 knots upwind. Below 8 one of us is sitting forward on the bow trying to get ass end out, which typically helps .5-1.0 knots. In 8-10 we're still forward on the tramp, but not on the nose. In 15-18 she'll do 14.5 true upwind in relatively protected water. I'm with the other guys, your sails are definitely an issue. Our Main is still good after 7 years but we need a new jib. In any case, Merry Christmas to you and everyone else on this thread!
  7. Corsair Pulse 600

    We use a Honda 2hp longshft on our 23 foot, 1100 pound Osprey. Goes about 6 knots in fairly calm seas. Not sure why anyone would need to motor in significant wind except to get out of harbor, you'll go far faster under sail! And we can always get out of the harbor, albeit slowly, even in 30 knots. Pretty certain 5hp is overkill for a 20 footer!
  8. NEW ASTUS 16.5

    Dayneger, Oprey is a home built 23' tri w/ no cabin. Main hulls is a heavily modified L-7 ama, Amas are extended Nacra 6.0 hulls. Won the PNW multihull championship this year. Probably get another rating hit . See my icon, and check out video. Video picks up speed halfway through.
  9. Corsair Pulse 600

    VP, see my comment on Astus thread....not likely for this waterline length if not foiling...
  10. NEW ASTUS 16.5

    VP, Doubt it. Osprey walks away from Sprints, 24's, M-23s, 28s, and many 31s in over 12 knots of breeze. Yet we don't sustain 20+ knots of boat speed. Maybe perfect angle and totally flat water like the speed course in Namibia along a sand bar.... But that's not real world sailing. Formula 40 cats like Dragonfly, yes they can. Astus is a real cool boat though, as is the Searail, Pulse 600, Weta, TC 601, and anything else in this class. I love seeing the variety of innovations, methods, hull shapes, trailering mechanisms, etc. that is showing up, all of them functional and effective in their own way! Hope they're all successful!
  11. Home Built 18' Trimaran (based on Scarab 18)

    Nice job on the boat Jetboy! Good idea Ed, and I'd like to get the down low on that myself for my most recent project.
  12. Homebuild

    Really nice job Jetboy! Like the paint job too. Can't wait to hear how it sails and see some video.

    MoMP, thanks for your compliment on Osprey. While there may be a touch extra wetted surface with cat hulls, in higher winds upwind it prevents squatting, which was Randy Smyth's primary complaint with the Multi-23 (even though they are mostly rounded not V'd amas, they lack buoyancy in the rear) I believe Ian purposely makes V'd amas as a built in safety factor rather than for any speed differential. V'd causes them to depress more, giving you notice when you're pushing too hard and need to reef. We have learned how to sail and balance (someone sits on the nose) the boat in lower winds (3-10knots) and even come out pretty well racing. Probably closer to an F-28 in this wind strength. However, in just a breath of wind, we definitely are slower, but I believe that has much more to do with the extra 13-15 feet of mast height on a 31 and wind speed as you get further up or closer to the surface, than skin friction of the amas. If you look at the big ocean tri's like the Mod-70's or the Maxi's, most of them have very rounded, very full ama sterns. Red Tuna, problem with Osprey coming to TX is its not so easily transportable for lake hopping, and I have a co-owner in Bellingham. If Lake Travis ever fills back up, I'll consider it more strongly. In the meantime, yes I will be down to Canyon lake this summer in the new boat, which I have appropriately dubbed Osprey Chick! Richard, thanks for the complement about Osprey! You gonna be in Cowichan Bay this year? I just made reservations...

    Gnarly, Yes a beach-cat rig could be used on any of these. However, due to the extra width, weight and primarily righting moment, you may have to add a set of diamond stays to stiffen it and strengthen it. Osprey weighs over 1,000 pounds and is 16' wide. We used a carbon Nacra 6.0 mast and added inner and outer diamond stays, and added some unidirectional carbon between the hounds and to just above the spin halyard exit. (Of course that last bit is not possible with an aluminum mast) However, added axtra stays is pretty easy and not too expensive.

    MoMP, I respectfully have to disagree. Gnarly, I have built 2 tris using cat hulls, and the amas work great. My 23' boat uses Nacra 6.0 hulls as amas, and my 20' boat uses A-cat hulls as amas. I'l try to attach photos. And they're FAST! At least the 23 beats almost all F-31's in over 15 knots of breeze. Not sure about the 20 yet, haven't tested/raced it enough yet to know.
