    Hello,

    This is my first post, but I was hoping to get some opinions.

    I've been looking into constructing my first Yacht. I've rather drawn towards the stitch and glue method but have a couple of questions.

    1) I've found a few plans on-line, notably the Vagabond 26. I've also seen a number of other boat plan sites. What is the largest Stitch and Glue sloop rigged yacht that has been made/planned? Do they come in over 30'?

    2) What are the construction costs for a Plywood, stitch and glue sailing yacht in the region of 30'? How is this broken down into Hull construction, sails, Mast, sailing gear and other?

    3) What size boats does Samual Devlin's Stitch and Glue book cover? Anything up to 30' size?

    I hope some people have some experience with building larger S & G boats.

    Regards,

    Tape and glue may be useful for larger boats, but are you sure you don't want to raise the frames and bulkheads first (and build some of the interior), then add some stringers and then have something to fasten the skin panels to?

    Here is my estimate:
    1/3 of the displacement may be cargo, crew etc.
    1/3 may be "the boat"
    1/3 may be ballast, probably less in modern designs.

    So, if your 30 footer have a displacement of three tons, you need one ton of wood and epoxy. This is a rude estimate, of course.

    Take a look at the material list for Didi 26 for example,
    http://dixdesign.com/did26mat.htm
    My estimate of the plywood sheets listed is 500kg.
    The finished hull is approx 400kg, then you have 400kg of lead, lightweight displacement is one ton and loaded one and a half (1500kg).

    My estimate for the Didi 26 is
    10.000 Euros for the complete hull and interior, plywood, epoxy, lead for the bulb and aluminium profiles for keel and rudder.
    5.000 for a complete rig with standing and running rigging, ready made, double that for carbon.
    5.000 for all hardware on deck, hatches, stanchions etc,
    5.000 for new sails, more for raising sails, much less for second hand sails.

    If you want a cheap boat, find a second hand rig first, then buy some second hand sails and gear, then build a boat to match :)

    Materials may cost 10 Euros per kg, plywood a little less, epoxy and glass a little more. It depends on your sources and the quantity, of course.
    Since you are in UK, check out Robbins Timber in Bristol.

    A crude estimate for building time is one kg per hour :)

    If you want to try something smaller first, here are two boats I like,

    http://www.geocities.com/cdbeckwith/iBoat/i550.html (stitch and glue)
