Thank you Tom for a good Hydroplaneur report. They performed several tank tests before building this cat, but perhaps the idea was not a good performance, but ...
... No problem with your horn. I have played with "Freeship" and "Michelet" some time ago and had a look at old papers. But that was yesterday and drag is only...
Depends alot of what you're trying to do. The video on Utube is very obviously a pair of windsurfers tied together catamaran style with a windsurfer rig. No...
Gooday Manfred I have added the Norward pages on leeboards as photos in the album 'Rudders, centreboards and leeboard. Also I have attempted without success to...
Ian thank you, I have sent you my address via bigpond.com. From the copies in the folder I could identify the book of Joseph Norwood Jr. which I have already...
Re Nielsen, Pogo has replied that the 34 Janus with dory style hull keeps up with F boats in most conditions. Rather radical information one might say as if...
Tried the German Yacht forum but registration is required to open photo files thought I might be able to use yahoo translator but it does not seem simple....
At long last I am ready to put the first coat of antifouling on my Tiki 21. I wondered if there is a special technique for getting the antifouling masking tape...
What I always do is to attach the tape at one end, either around the bow or the edge of the transom. Then I pull out a length of tape equal to the length of...
Barrie, if you really want to join, registration is very easy. But from my experience the postings in German Yacht-Forum are not so interesting as in...
If the hulls are level set up a string line parallel with the hull side & not quite touching it 3/4" above the desired top of the antifoul. Use a short spirit...
If you are able to set the boat up as it will sit in the water, you can use a laser level or a water level to mark out the line. Water level is simply a piece...
You can rent a laser level from a tool rental place which will work nicely or make a water level with a long piece of hose that has a clear section at each...
Good to hear from you, Reino! It's been a while. ... I've not analyzed the race results any more than that email. I also don't have any performance data on...
... Hi Tom, While I agree with the overall point being made, I'm drawn-up short with the analogy. Porsche Chris Ostlind Lunada Design www.lunadadesign.com ...
I do it exactly as Larry does. At least on my Trailer Tri which is only 24 feet long. On a much bigger boat I would use the laser level and tape very...
... I know this is an older thread, but I thought some might be interested in how Tony Bigras (of Miss Cindy fame) designed his 50' aluminum cat to be...
I have done several waterlines on a variety of boats and have used either a water level (transparent tube) or when I could get one, a dumpy level. This was...
Hi IN, Are you new to the list? I dont recognise your handle. Cheers, Peter ... From: imaginary.number@... To: multihull_boatbuilder@yahoogroups.com ...
Mike is brilliant. He used consult with me on my conceptual brainstorming of projects. He is genuinely original and his skill is huge. I would try to retain...
... If somebody is real interested in the Hydraplaneur here the link http://www.parlier.org/hydraplaneur/bateau/caracteristiques.php?lang=eng ... or if this is...
I used a laser pointer on a good photo tripod. You need to get the laser pointer at the same height as the waterline directly opposite it but the boat does not...
Hi, I'm designing a basic, simple, no frills cruising tri 34 foot LOA. My main hull has an overall Cp of 0.61 which I'm happy with (or am I wrong?). But,...
... I think for a tri, the pitch damping has as much to do with the interaction between the main hull and ama as it does to the main hull alone. John...
Thanks - I'll see if I can obtain a laser pointer. I had forgotten about the transparent hose trick too - not a bad backup plan. Thanks for the photo, your...
Just a short note to let you know that I've put-up a couple of new articles on my website which just might interest the boatbuilding members of this Group. The...
Hello, I am building a small beach proa and I am now in the final adjustments. I bought a used old Class A catamaran aluminum mast and mainsail, with no reef...
Hi depth of reef seems to be a fairly subjective thing. Some designers have only 1 reef, some a smallish first reef & a big second reef. Others have 2 equal...
