Builder's expanding foam

Re: Milk Bottle buoyancy

Good one Awol Marisca, I was just asking for that really! /forums/images/graemlins/smile.gif
Must admit that I have an inherent distrust of all things mechanical, hence on my power cat (if I ever do build it...) there will also be a suitable pair of oars, and maybe even some form of small mast and sail.
I am a die hard raggie at heart really, but I have some crazy ideas re power cats for commercial fishing here, and this 16' version will be the prototype. If it works, then I will just scale it up to a 24' version and then a 32'.

Re: Builder\'s expanding foam

I was using a can of expanding foam, I must be careful how I write this: someone who had been in the furniture trade looked at the can and advised me not to get too close while using it, and that allegedly 2 people in the offices of a foam factory had died from inhaling similar fumes over a long period. In the confines of a boat this might be important. I believe it is inert when cured.

Cheap Flotation

Apologies for the late contribution, but I've been away for a week or so and am just catching up.

Before buying successive E***s which completely avoid the sinking problem, I owned a boat (a Vivacity 20) which tried to sink on me: a foot of water over the cabin sole; Mayday, flares etc. - an interesting event in retrospect... After fixing the immediate problem, I thought about the whole issue of adding positive buoyancy. I settled for lots of inflated wine box bladders stuffed into the space below the forward bunks and held in place with expanding foam. This (a) usefully recycled the otherwise scrap bladders, (b) saved the cost of the equivalent volume of foam, and (c) gave a goood excuse for drinking more wine (it's not that I really want it, it's for the boat...).
