    Default Goat Island Skiff Questions.

    Hi

    I'm thinking about building a sailboat and the Goat has piqued my interest and I have a few questions,

    Are those gunnels a lot more comfortable to sit on than they appear?

    I don't drive and it's about a half mile by push cart to the boat launch so lightness is really important, especially on the way back

    If I built a GIS out of 4mm bs1088 Luan and put 6 ounce fiberglass on the outside would it still be sturdy enough?

    How much does the sail rig weigh all together?

    2B

    Hey, welcome.
    Do not try to build the goat out of 4mm plywood. Epoxy and glass weighs more than wood anyway. Build it to spec. If you want to save weight, use pawlonia in place of Cedar and be economical with materials everywhere. Keeping the weight of a goat down is the product of a lot of little choices, not any single and radical alteration to the specs.
    I don't really joke out much, but some builders have added an extra layer to the gunwale stack to beef it up and make it easier on the bum.
    Fair warning--this place is pretty dead. I regret it sometimes, but the goat FB group is much more active.

    G'day

    I'll second what Brian said about building to spec. I deviated adding the yawl bits and enclosing the centre thwart this added about 30 hours to the build and adding weight.

    I used 6mm gaboon/okume ply and paulownia for framing, DF for inwhale and outwale, Jarrah for gunwhale cap and skids. If I was to build it again I'd use Tamasian Oak instead of the Jarrah as it's easier to glue, work with and weighs half as much.

    As a yawl she weighs a bit over 90kg (200 lb).
    Without the mizzen about 80kg (175lb).

    These weights are for hull, spars, sails, lines, safety gear and oars.
    I've not included the outboard or anchor.

    I wouldn't worry about fibreglass other than as per the plans. The skids protect and strengthen the bottom.

    Cheers Dan

    Thanx Guys

    bummer. 175 lbs would be too heavy, I could still get it back and forth to the boat launch but it would be enough like work that I wouldn't do it very often.

    From what I've read about construction all panels are encapsulated in several coats of epoxy, the materials list I stumbled across said 12l/3 gal of epoxy, if so wouldn't adding fiberglass cloth add very little weight at all?

    LOL, not that I'm a fan of epoxy, every time I mix a batch I spend the next 6 hours worrying that it won't cure properly, in fact I'm supposed to be mixing a batch right now to fair a pair of amas I'm making for a little dingy I'm working on, or would that be a dinky dingy? you could call this post constructive procrastination

    I'm pretty much stuck with using marine grade luan and pine/spruce as that's all that's available here, or at least the best of what's available here.

    How is the goat for swimming off of? I do a lot of snorkeling.

    G'day 2B

    I can't speak to using the GIS as a dive platform, however Enrico Franconi on the GIS FB group has fabricated a boarding ladder for his.
    Regarding plain epoxy vs fibre glass, fg will add a minimum of 1kg (based on area and 1:1 wet out of 120gsm cloth). With the goat the weight reduction is a matter of little reductions where possible to bring down the total.

    Bare hull weight the goat has been built down to ~55kg (120lb), but that is only through materials selection and disciplined epoxy use.

    Check the weight of the luan ply as you can add as much as 20kg (~85lbs) to your final weight. Gabon okume is ~9kg a sheet.

    Here is a video of some snorkelling happening. You need his nifty ladder idea though.

    Hull itself can be as light as 105lbs with a lot of Paulownia in the solid timber. Move it to where you will launch then add the other bits. You will need some weight of gear in the boat to stop it capsizing. A big picnic is a good idea.
