    Re: Just Got My New Sails

    1/8" is generally plenty for lacing small sails. One good source for 1/8" three-strand polyester if you want something traditional looking is the drapery department at your local fabric store....

  3. Re: What caused the thousand pin head sized blisters in my paint

    If you did any fairing with microballoon mixes, or used high-build primers (most of which contain microballoons) they can cause lots of mini-craters. When you sand these clean and smooth you are...

    Re: Sprit boom advice needed

    You don't seem to find many people who actually believe that having a spar distorting the sail's shape on one tack (sprit on a spritsail, masts on lugs or lateens) really makes much of a difference...

  9. Re: fuselage skin kayak, recognize the design?

    Heavier than most or not, sleek and fast or not - it still probably handles better than a very large percentage of the current crop of rotomolded, heavily recreationalized "kayaks" do.

    Re: Balanced Lug Sail Shape?

    Luckily, it seems to dissipate, so the gun rack doesn't smell for long, but you do want to get the rags and patches out of the house and in the garbage ASAP.
