Thread: Son of Goat project

I like Mik's internal layout as drawn very much - nice and simple, all the structure and buoyancy necessary. Only downside is lack of an intermediate seating position off the gunwale, think this could be solved by putting a 100mm or thicker piece of closed cell foam in the boat for sitting on.

Like keyhavenpotters idea/suggested position of drain tubes, will think about implementing this on my GIS with fibreglass tubes.

Don't like Watermaat's water in the central compartment as ballast idea, unless the water is in bags/containers that are tied/restrained to the bottom. Half / third full of water in there would slosh around and destabilise the boat, full of water would be too much ballast - 150Kg/litres?

This central compartment is about 135 litres, and meant to be additional flotation ( and dry storage ). But since it is devided left-right by the centerboard case it could hold about 25-30l of water on each side to have some additional weight. It's not designed to be a ballast-tank, but could double in this way.
Personally I do not think you really need ballast on a GIS single-handed......but since I did not try it yet I am open to any advice given in this forum.

SoG design should not need ballast in the first place.

Hello MIK,

Any progress made with regard to your thoughts about the internal layout of SoG?

What happened to your original idea of creating two versions: 1 fast and furious sailor (with a hull shape inspired by the UK National 12) and one more sedate all-round version?

Best regards,

Joost

Howdy Joost,

There are a couple of things I am happy about with the version above but some things I am dissatisfied about too. Not feeling good enough to move on as I feel I am still processing.

Basically I think it would be a nice boat for me, but I wonder about its mass appeal.

In a way would be nice to have the same layout as the Goat - front and rear tanks and the seat in the middle, but I think it would reduce the current buoyancy just a bit to far.

In a way the current drawing is a hybrid between the height and volume of a cruiser and the narrow bottom and buoyancy arrangement of a racer.

Also all that surface area in the buoyancy tanks. Maybe there is a different way. Maybe side tanks for the racey version.

The national 12 idea is good because the narrow waterline gives quite big performance, but I do wonder about the flare - the rowboat is a bit tricky to build because of the side flare. It would be easy to build over a jig, but that is not the point of the GOAT family.

So just struggling a bit at the moment.

Make sure that we can sail the boat standing up like the GIS.

This is very important. I can't sit down because of my bad back, but I can sail because I can stand up in the Goat. When the wind gets tough, I can get on the gunwale, but the ability to stand most of the time is very important. I know you like standing Mik, this is a huge asset to the design!

That's an unusual criterion for boat design .... but I agree!

I'm trying to think of a sail boat that you can't stand up in. I thought maybe a Moth or a a sailing canoe, but then I've seen pics of people standing in those too.

You're sure getting a lot of mileage out of that video Michael

For others - that's me and my mate in the boat with Michael

Haha!
Tell to the truth I've sailed my BETH in standing position few times ... Sorry, but I haven't photos.

I'm talking ballroom sized space. Nice and comfy with room to move and balance and scratch your behind.

Hey Duncan,

Nice to hear from you! I do get a lot of mileage out of it indeed. Duncan and his friend were sailing for something like one of the first few times.

They spent the afternoon trying it out for themselves in a PDR.

They were getting the hang of it quite nicely.

It was a really nice day at the Biting Midge's house

MIK, I think the real meaning behind Christophe's post is that he wants a trapeze so he can dance around the gunwales perhaps? A bit of sandpaper glued to the tiller extension would work for the other.

HA! Funny! Hey, it can get itchy in the wetsuit, as I'm sure you know.

I was wondering how I could get a trap up on the Goat without getting in the way, but that would take more dedicated hardware and I'm just coming around to reefing instead of capsizing and pushing it all the time anyway. I shouldn't regress.

A trapeze?

That would be funny. A balance lug with a trapeze would be a strange contrast.

I am sure the boat would respond very well. But the trapeze wire might pull the crew forward quite hard because of the shortish mast well forward.
