quote from my boatbuilding friend
 

I'm working on adding a bridgedeck cabin to my catamaran.
Quote from a friend who is helping out on the renovations:

"You know the boat renos are getting serious when you're on
your third chainsaw chain".

Chainsaws cut through fiberglass very quickly but the chains
don't last too long, even with frequent sharpening.

Oh, in about 15 days we're removed the old little steering
pod, outboard motor wells, old mast beam, and cockpit sole.

Fiberglassed in a new much bigger carbon mast beam, cockpit
and cabin sole so far. Oh, yeah, I'm also part way through
installing a new diesel (where there were only outboards
before).

Hi

This is a serious issue, my only advise would be to see what tungsten
bits could replace the chainsaw chain, ---- Still even such for routers
are soon vorn out but it is the way profesionals work ,cutting
fiberglass it also make a much smoother cut with a router and tungsten
bits --- they work longer and can be sharpen but you need to send them
to a workshop, as this ask special mashines not just the sharpening
stone.
-------- But maby a router bit don't reach enough.

A SawZall with a carbide blade is designed specifically to cut fiberglass.

What Lew said. And there are carbide blades for saber saws, too. For
delicate stuff, the HSS fein multimaster blades hold up remarkably well.

Evan,
What are you going to do with one(a) diesel in a catamaran?

I know - we have an original 50 year old Sawz-all. Carbide
blade and all, but the chainsaw is faster and has a longer
blade to cut through secondary structure.

It's the main propulsion engine. We have a Yamaha 9.9 4
stroke 'high thrust' outboard as the "docking thruster".
It's positioned against the other hull to provide a good
turning moment.

The outboard used to be the main propulsion motor but it
only gives 5.5 knots and ventilates in a chop. Also it's
range and reliability is less compared to a diesel.

Evan

Evan,

You should hang a card and do this professionally. Aside from the
slight image problem you might face arriving with a chainsaw, mask and
goggles, you'd be very good at it!
