    Hi, I live in France in Auvergne, a moutainy area full of lakes... I have always wanted a boat so i have decided to build one. After talking around with a few English friends i have just bought "build the new instant boats" by Harold "dynamite" Payson. I like the look of the gypsy vessel but i don't understand the plans they are in inch's... I need a metric system version to be able to reach my dreams can anyone help me? Thanks :)

    Either buy a standard measuring tape (about U$10.00) or multiply by 2.54.

    There is almost NO way to convert a "imperial" measured plan into a "real" measurement. It drives you nuts! Leave it! You do much better to find a metric planned boat, there are thousands on the market.

    Apex1: That is ridiculous. Converting linear measurments only takes one multiplication.

    Just buy a measuring tape scaled in inches and millimeters.
    Et voila you have an instantaneous converter!
    Salut,

    Jozz,

    "Gypsy" is said to be a very nice boat. My own Bolger "Diablo" is from the same series of designs; his plans are easy to read and everything fits exactly as it should.

    Don't let the fact that a design is in imperial units dissuade you, if you like the boat otherwise. On Bolger's "instant boats" you can just use 6mm plywood where 1/4" is specified, 9 mm in place of 3/8", and 12mm instead of 1/2". Dealing in inches isn't terribly difficult if you have a suitable measuring tape.

    To take your own measurements from Phil Bolger's plans, you should have an "architect's" scale rule (about $12)- an "engineer's" scale won't work. Odds are, though, that you won't need to do so; most of the dimensions you'll need are already on there. His plans do require you to loft out the panels full-size for cutting. If you know how to measure in a straight line at right-angles to another straight line, it's dead simple.

    Cassavechia has the best advice. Get a tape that has both imperial and metrics printed on the tape. Gypsy is a very competant boat for its' intended purpose. It rows well, it sails well, it is easy to build. It is not the ultimate best at any of those things but it certainly compromises them in a sensible and satisfactory way.

    You are all sooo right, it is easy to convert.

    Have you EVER tried to build a boat using "the wrong" measurements ????

    Do it, comment again, and love that experience.

    Regards
    Richard
