Of course if you get bored you could always peruse this rather long thread covering many designs.. https://www.boatdesign.net/threads/multihull-structure-thoughts.62361/

I sort of agree with plywoodboy until you realise that your budget doesn't allow you to buy a boat but you can afford to build one.

If you are looking to build one maybe build the 16, 18 or 22 without the lid? Team Scarab multihulls Maybe the W17? W17 Study Profile (smalltridesign.com)

Awesome thanks. I am guessing there is not enough meat in the fork get it out to 60mm? Looks like I'll need to make one out of glass.

Howdy. I was hoping someone could take some measurements of bits on an Open Skiff/Bic. I am looking to use some of the parts on a Scarab 10 build I am doing, but I don't know dimensions of bits. If someone could measure the mast diameter where the boom fork sits that would be great, also the boom diameter that the fork plugs into. I'd like to use the boom fork for the scarab 10 if I can. The scarab 10 has a 60mm mast section and a 48mmID boom section and I am hoping the OpenSkiff/Bic fork will fit. Thanks!

Hey just so you know there seems to be some missing text on point 2. Raising the mast with the hinged mast base 1. Always lift the mast in line with the base – it is not designed to take the force exerted on it if lifted from the side and this may cause the plate to bend. 2. Tie a length of rope and a block to the trolley so that you have the Tip: You may find this is easier to achieve if you stand inside the cockpit to raise the mast.

Any reason you can just glass a channel connecting them both? Make up a prefab fibreglass channel at home and glue it on to the underside of the cockpit?

Thanks It's a Scarab 16 without a cabin and a slightly larger sail plan. Main sail is from a Taipan 4.9 and jib from a Nacra 4.5 http://www.teamscarab.com.au/scarab16/design.html

Anyone know what the extra little appendage is behind the swing center board?

How about a multi. http://teamscarab.com.au/ Or https://smalltridesign.com/W17/study-profile.html Or a woods? http://www.sailingcatamarans.com/index.php

I've never heard of using expanding foam for a fillet before. Surely that has the sheer of toilet paper and that joint between hull and deck/bridge in the tunnel could not be considered load bearing, just used to keep water out and make it look good. All things considered though 40 years is pretty good and I'm sure it's seen some large waves and loads in it's time. Nothing lasts forever. Thankfully no-one was hurt or injured.

That's pretty excessive non skid isn't it?

How well does the electric go?

How about some reviews as you try them out
