To echo 'Nasher' Wow! you are wasteing your talents,Matt H and I were saying only the other day [Matt is a bit of a military model buff-usualy life size though!!]
there would be a market for scale models of popular [and maybe not so popular]R.I.Bs that you could possibely customise with things like tube colour,seating,ect to be a fair representation of your own craft.
I can imagine lots of R.I.B owners being seduced by a 2 foot version of thier,Scorpion,Osprey,Ribcraft,Searider...or whatever!!

So - if there is still a wooden hull around - why not get out the foam , make up a mold & start banging out hulls for a sensible price ? ( Either GRP - like the banana shark ones, or if someone has a resonable vacumm forming machine they could just be done over the wooden hull)I'd by 2 at least - then we can all go & buy some pipe lagging/ paint & have scale versions of out own boats- stick the bggest motor we can in them & race them ( much like the real ones ! )

Got to be someone on here who can make a few quid out of all of us by doing this ?

for the hull i just made up a dummy from card so that i could get the shapes right then made the hull from really thin ply wood from an old wardrobe ,with transom from a much thicker peice then all stuck together with glass fibre resin from a car shop ,i just used 2 formers or ribs to keep the shape of the hull and for the floor to fix to ,then gave the whole lot a couple of coats of old marine topside paint. first thing to do is see what foam or pipe that you are going to use for your sponsons then try scale the hull to fit ,just try experimenting with a small hull at first using card and selotape then that will give you some idea how to go on ,mine was a bit fiddlely more than a normal rib hull as the atlantic hull has a flat on the keel so that it can be run onto a beach .

That's fantastic! I wish I had the time, patience and ability to make a model as good as that.

Somewhere at my Mum's I have the plans for a SIB - IIRC, the sponsons were 'real', made out of rubber (neoprene?) sheet. I can't remember how you were supposed to inflate them - next time we visit her I'll see if I can dig them out.

Unfortunately I never got very far with the build - pocket money didn't stretch that far, and by the time I had real money I had discovered motorcycles

Cheers

My son was so excited when he saw your fantastic RNLI model and he has started making one this evening.He loves ribbing and model boats and wants to try and make a model rib.I'm not allowed to help so It'll be interesting to see how it turns out.
