Re: Anchor Chain

I've never heard of length of chain = length of boat, maybe for tinnies ? In coral you want all chain, and if you've got a boat you're going to want to be near coral. My boat similiar to finally, 12.5m and 6.5t Have 2 super sarca anchors which have very high holding power compared to older CQR types...

Re: MV catapult

I just glued foam blocks on then got out the chainsaw to rough them in before boarding and glassing. Who doesn't enjoy a bit of chainsaw action? :D

Re: MV Catapult Windows

Paul, good to hear you are back on it. The flex issue is one of a few with poly. I'm hoping to get the polycast uv-sc which will obviate the need for tinting altogether. It's also very scratch resistant ( so much so you can use windscreen wipers on it )so should stay looking good a long time. Can't ...

Re: MV Catapult Windows

Paul,
I'm using 10mm acrylic for my windows. After a fair bit of research I wouldn't use polycarbonate for large windows like ours, acrylic is better suited.
How's your build going ?
cheers

Re: MV Catapult Windows

I should have taken some piccies. Boxed the cutout first, 30mm mdf taped up, set in 40mm from edge(or whatever size flange you want). Attached 90 degrees to window cutout with blocks and hot glue, fairly easy on the straight sections but lots of cuts on the curved cutouts. This lets you get a good s...

Re: MV Catapult Windows

This is how I did mine. Marked windows and routed trench, filled this with uni glass 450mm wide rolled up into rope and pressed into trench with 403. Cut out windows. Taped windows up and made mdf mould 40mm from edge to create neat flange ,and then put back so that they protruded 4mm internally ( t...

Re: Not a build, a partial rebuild...

That's some pretty impressive damage and repair work there, showcases some of the advantages of duflex construction for sure. Would be devastating as an owner builder to see your own boat in that state. Is there a separate cabin sole in Oram boats(ie not the hull keel), doesn't appear so from the pi...
