I've been doing some 3D printing for my Matilda, as I want to make better use of the interior space by making mounts for various equipment - such as being able to mount a torch to the bulkhead, and hang glasses from the centerboard case. (The Matilda isn't blessed with storage space).

However, there's a couple of jobs I wanted to do for outside the cabin - a holder for the hand-held radio near the tiller, and a piece to help with mounting the compass. I'm using ABS (I can't see how PLA could be viable for a boat), but I haven't done any printing where it might be exposed to elements. Has anyone had any experience with this? If so, is it a lost cause and I should just focus on the interior, or can I get away with some ABS in the cockpit?

Some stuff I found with google:

http://www.sdplastics.com/ultravioletresistance.html
"ABS is not suitable for outdoor applications because of its poor UV resistance. Current UV stabilized grades refer only to color fastness not mechanical property retention."

It looks like there's lots of good info out there to be found.

Thanks. :) It looks like ASA is the way to go - I've ordered a roll and I'll see how that works out. I'll keep the ABS in the interior, though.
