    Re: Outhaul on loose footed main sail

    Velcro and webbing seems awfully out of place on a sail made to look traditional with narrow panels, cringles, etc. - especially when it could be done with cordage. It's like those "classic-look"...

    Velcro? The stuff that loses 50% or it's holding power when it gets wet?

  10. Re: Making a standing lugsail for my Argie 15 (Todd Bradshaw design)

    Yep.

    You will need to roll the sail like a scroll for nearly every sewing pass through the machine. Having tried all manner of methods, clamps, tubes to wrap cloth around, etc. to roll it...

    Agreed. Though those nearly square spritsails don't have a really snazzy looking profile I've always liked them on Norse boats. They just seem to fit. I have a plan I drew up for one in my...

    Not shown because it is not needed on that sail. It can certainly be a good thing on lugs with really long luffs, but I've built a bunch of these over the years, doubled the luff tapes up for...

    This is the first sail I ever built (1980) and we still use it today. I put a considerable amount of time into the design because I wanted to have a tri-radial lateen for my own use and had...
  22. Re: Sail making and the conundrum of the camber

    This line of "reasoning" makes absolutely no sense to me at all, and it will certainly never make you a good sailmaker, rigger or boatbuilder. Cut corners in order to finish the job faster? Since...

  35. Re: Making a standing lugsail for my Argie 15 (Todd Bradshaw design)

    Thread and needle sizes for hand seaming have always been determined by the fabric's weight, and a lot of traditional sails were made from fabric too light to really be called "canvas". In general,...
