Thread: Helping Build the Goat Island Skiff Part III

Thankyou Joost!!!

There are even more videos here ...

Interesting and useful documentation and the videos are great fun.

I noticed Olivier ran both halyard and downhaul down the starboard side of the mast. Do you suppose that was an oversight or does he see an advantage?

One other thing I noticed, MIK. His butt straps are much wider than the ones called out in the plans. Did you increase the width in later revisions?

Howdy MAM,

Didn't notice the butt straps. There is no hull joining reason for ever going wider than 20 times the ply thickness as a general rule. In earlier plans the straps were a little narrower than that, but no detriment in any of the boats. But now I stick to 20 times the ply.

I can't see any advantage in running both halyard and dowhaul on the same side. Seems to run the risk of increasing halyard chafe and also jamming more when lowering.

On Biting Midge's Goat I have sometimes got a big confused when rigging and ended up with both on the same side. But only by accident

I seem to recall my butts were 70-75mm or about 3 inches, which would be 10-12 times the ply thickness. They are sized per the plans so it must have been before you went to 20 times the thickness. I'm not really worried about them just curious about Olivier's wider ones. I'll have to go back to the pictures in the Duckworks article but I'm thinking they were about 6 inches wide, by eye. Wider might be stronger but narrower gives you a smaller flat spot to fair.

Correction--in the last picture in part 3, the one of Tiffany sitting near the bow, the butt strap to the right appears very wide but it isn't. I went back to the build pictures in part 2 and see a butt strap about the same size as mine. It was just a little optical corn-fusion.

MAM - Our GIS has the narrower buttstraps. It has been through far more rugged use and abuse than I'm sure Mik ever intended. I've managed to bust open the bottom in three spots and the sides in two. The buttstraps, however, abide.

Ha, David,

I feel so reassured now!

Truly, as Mik knows - the bulk of the damage was done during one horrendous incident. No boat should have been forced to take the abuse that SIsu did that day. The one day, we were the only sailbooat out amongst our group of about 10 boats. No one else had the machismo (or was that stupidity) required. Dr. DerringDo had to give it a go. The GIS stood up to some stout winds. It was the only time I've used the second set of reef points. Bringing her in on that shallow, churned up shore - littered with stumps and rocks - was just too much. I ran her into stumps, and was lifted on waves and dropped onto rocks. And that was coming straight in. The only other boat was out was a larger powerboat. When he tried to beach, his primary outboard lost a sheer pin, her secondary was too small to master the conditions, and she pinballed down the shore until eventually wrestled into submission by a gaggle of Coots and helpful fishermen. She took quite a beating too, but, being built of much thicker ply, at least did not get holed.

Through all that, even though Sisu clearly bounced at least once on a rock just at the buttstrap, there was no sign of failure of the buttstrap. Good thing she was built of quality materials. 6mm occoume BS6566 ply. Hate to think how she'd have fared if she'd been constructed of lesser stuff.
