What boat would this chute be for? I understand that the decision has been made not to go ahead, but some context for this thread would be nice.

I have tried an assy kite on the Blaze, bloody brilliant when it works but launch and recovery is difficult without dedicated systems. I can manage it on the Spice in the light but I'm handicapped on the Blaze by not being allowed to drill for fittings (not complaining, I don't really want to irrevocably alter the boat) so everything has to be jury rigged to some extent. I got a chute arrangement working from " ally tube last summer but, not surprisingly, it wasn't strong enough and failed. Might try a bucket again but still use a downhaul recovery system (when I first tried it I recovered from the clew).

Lots of good points, for which I'm very grateful.

Actually I reckon I'm going to persevere without a solid chute or mesh, just the bag on the floor.

It's not that I'm a purist, I've just spent too long on DIY (and I'm rotten at it) and not long enough afloat.

But I'm sincerely grateful for so many points of view.  Smile

Bit of a tangent but some guy has made himself a full carbon Mirror mast..... Grumpf would approve...then burn the hull.

Waste pipe is very very heavy too, as others have already said weight in the bow is a killer. Especially when you add potential weight of water filling the chute. You will likely be better moulding a solid chute out of glass until you are in the cockpit then going for a mesh bag to finish it.off. That way as least the solid part of the pipe and be bonded into the ribs you may have t cut in to.

On one of our Merlins, OH built a plywood spinny chute which tapered - wider towards the rear. Once well laden with varnish this worked for several years.
Also the mouth of the chute has a smooth stainless tube about an inch diameter across the rear edge of the chute mouth for the hoisting line to turn around and this prevented the line wearing grooves in the timber as it has done on another of our boats that's twenty years newer!

Hurricane SX and a few other multihulls use solid fibreglass chutes.

There's a pretty big one if you are going through a buoyancy tank...
