I just got off the phone with Mr. Colvin. He has been using top gun for years and that is what I am going to use for my gazelle. Happy sewing Lawrence Thanks for the blog, and the source for top gun.

Happy sewing

I don't have first hand experience with this, but check out a cloth called Odyssey III. http://www.rochfordsupply.com/product_listing.asp_Q_CatID_E_419_A_SubCatID_E_487_A_ProdID_E_3338 It is polyester cloth (=abrasion resistance) with acrylic coating (=uv resistance) like Top Gun. But 6.5 oz instead of 11. It is much much cheaper than ordinary sail cloth. Only downside is that it is hard to tape together during sewing, since it is so slippery. We used duck tape, clamps, needles and free hand strike up marks. /m Hi Terry.

Been reading your comments on TOPGUN sail material. My junk sails are getting tired and aged. I made them of poly/cotton so now I'm looking for a better material that will last onger. Can you tell me where and how much and most important can it got in 6oz weight. Been looking on line but found nothing so far. Appreciate your help and advise. Cheers Terry.

I haven't tried it out in the right conditions yet. But Tom MacNaughton, the designer of the boat, suggests using the wind vane to balance the boat in a gale, if I remember correctly. In light winds, you just let the sheet go, and the boat will stop. /m Well, I suppose you mean heave-to in heavy weather? I haven’t tried it out in the right conditions yet.

Arnes boat is about 6,600 lb, while Linnea is about 22,000 lb. At 15,000 you would want 660 sq ft. At 18,000, 725 sq ft, quite a bit less than our 800, since sail area scale by the power of two and all other things, like cloth, battens, yard, etc, scale by the power of three, since they have volume and area doesn't. Well, yes. 800 sq ft is considered quite a lot by Hasler/McLeod. And I do agree that the sail is heavy to hoist. My daughter, Ida, was 5 last summer. And she could crank at the winch, but then it would take her a long time to hoist the sail... We are now using a really heavy solid yard but are thinking about exchanging that for something else, maybe hollow wood, or aluminum. (Something like my boat neighbors mast and my angle grinder...) Anyway, there are some things in favor of one mast on boats like this (heavy cruising boats): - With two masts it is much more difficult to fit the sail area without using a boomkin or double sheeting. (It is hard to understand this until you try to draw it yourself.) - Two masts give high aspect ratio sails = less efficient. - The two masts have to be almost as thick as the single one, since one mast needs to be able to heel the boat down. - The aft mast will block the forward mast when running (major problem!) - Two sails is two sails. Hoisting two smaller sails takes more time than hoisting one larger sail. - By moving the sail with the parrels, it is easy to adjust how heavy the boat is on the rudder, no need for two sails to do that. I'll be happy to answer any other questions on this. /matti Hi Norm,

I thought Linnea was Arne's boat and this was his blog. As I now believe I understand... you built and own Linnea. It is Linnea I am interested in. I am in the market for a 15,000 to 18,000 lb boat with a junk rig or one that is suitable to convert. I was under the impression that 800 sq. ft. of sail generally required a split rig. To find you doing quite well with 800 sq. ft. in one sail widens the possibilities of boats suitable to convert. Thanks, Norm Matti,
