Hi, I have done some more tests recently on the relations between camber, area and aspect ratio and for me the pieces of the puzzle are falling into place at...
Dear Jonqueurs and Jonqueuses :-) This weekend I had the opportunity to sail someone else's Colvin junk schooner. I found I could make the boat "go" ok, and...
I'd say you had a very observant first sail on a Gazelle. Took me longer to notice as much. I don't use a crutch for the main, so I just drop the main into the...
Hi Steve Battens on this boat were (to my surprise) not very rigid. they were lengths of, hmm, looked like 1x4! yard and boom were heavy alloy tubing, yard...
I took Tom Colvin's advice (of the time) and used pole vaulting poles for battens. They work well on the foresail with its 250 sq ft, but are too flexible on...
... so where can one buy structural bamboo in such large diameter? and how can it be shipped in lengths over 10 ft? anyone succeeded in ordering and...

David, isn't it rather expensive to buy GRP battens from the UK if you are in Hong Kong? or are you no longer resident there? I can't imagine how expensive...
Hi, All Here is a link for those who wish to learn more about making a hollow wood mast. I doesn't look that difficult. It is probably the cheapest fairly...
I have ordered bamboo battens from a tree farm in Gerogia. They should be delivered in about a week to me in Florida. I believe these battens will do the job...
A few quick comments on De's recent messages: 1) Sailcloth. The material you want is not Sunbrella, it is Top Gun. Top Gun is made from dacron thread coated...
... not at all, I am always glad to have my nautical terminology corrected and improved. so the smaller sail on the schooner is the "foresail" as opposed to...
Hello, We've been lurking on this list for a few weeks now and having just seen the posts about the Gazelle thought this would be an appropriate time to say...
... Colvin seems to disapprove of completely stayless rigs. I think the unstayed rig looks cleaner and better, but presumably he had reasons for including...
I wouldn't think of taking off the stays without replacing the masts, and then I would increase the size of the forsail to equal the main and moving the mast...

Steve, On stays,I agree (but hey, keep the bowsprit, they look great and are fun to ride on). My boat (50 ft, 25 tonnes junk ketch) began life without stays. I...
It never crossed our minds to try to re-use the ketch rig masts. We'll probably use aluminum pipe. A friend of ours used pipe on his Gazelle and the spars gave...

Correct, though Sunbird refer to their battens as "poltruded" GRP which I presume has something to to with the way they make them... all I know is they seem to...
