Have you considered the weight of 8' of 8" pipe? I don't see any advantage in rigid pipe over a mesh sock as long as the chute assembly works, and as iGRF says the bigger the better.

Of course, one issue with big is that it lets in a lot of water. You end up with a soggy, heavy mass of sail right in the bow where weight really kills. So you need to ensure any water that can drain, does drain.

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

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

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!

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.

I think glass or carbon moulding is fine just for the very front then mesh thereafter.
Like my old mirror 😀

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

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
