Re: Alum vs fg

Easton Alloy cats are not heavy.

Tim Mumby also makes very light Alloy cats.

Still, I would probably use foam or balsa. I think it will last much longer. The thin alloy needed for a light cat probably won't last IMO.

Not interested in building a light cat. Want a heavier plate - not extruded materiel. I've built with NidaCore and hate balsa.

Re: Alum vs fg

You've kind of changed your tune. Originally you were confident you could build a lighter boat in ally. Now you're not interested in building light anyway.

You've already made up your mind - you're gonna build in ally. Nothing anyone here says will change that. So go ahead and build it! And post photo's please.

Not sure why you are building a multihull sailing boat then

Because I want to and can. I examined the materiels and decided on the heavier metal. Yep, an alloy boat - works for me and works for our intentions. We will continue to build wood gulets.

Re: Alum vs fg

Ghostrider you are of course quite entitled to build whatever you want. But if you aren't going to keep a multi "relatively" light then you loose its advantages as a sail boat. But like I said not disagreeing with your right to do whatever you want to do.

Re: Alum vs fg

Ghostrider - hope the weather is treating you well on the rock! I am outside of Halifax, but come to St.John's or Corner Brook a couple of times a year, for work.
Anyway, have dreams of building the Mumby 48 cat, but for now am starting with building a 25' planing powerboat (Glen -L double Eagle). Have basically just got the frames up, and will be running the flatbar stingers in the next few weeks, then measuring / laying out hull sections to see what size sheets I need, and what makes sense.
Figure that I will either gain skills and want to build again bigger and better, or will get schooled in how hard it is, and will at least have a seaworthy and fun, if not professional and pretty boat.
Keep us posted if you build in Aluminum - would love to see pics and rational for choices, etc.
