Not very big; just big enough to rap around the top of the console a bit and stop the spray/wind getting in my eyes.

I used makrolon for mine, excellent stuff and easy to work with. recommended!

Yeh and it dosen't crack or craze after a seasons use.

I used makrolon for my screen, heated up over a gas stove 180deg, then bent over a worktop unit

what thinkness did you use in the end? 3 4 or 5 mm, the boat looks great by the way

Just thought I'd expand this to see if there's a view on what height works best.

On my DIY version - which I'd estimate extends to about 20" to 24" above the console - you can mostly operate the RIB (when standing) by looking above the screen - which I prefer for better all round vis - but it's also good for simply ducking behind when you see a big spray coming. Unfortunately my shorter 'drivers' have suffered slightly - having to look fwd through the screen makes it very difficult to follow other (more distant) RIBs etc in heavier seas.

Another slight advantage of a tall screen seems to be that the boat cover forms a nice tunnel between that and the A frame, meaning I can do plenty of jobs without removing the cover.

The main drawback of extra height seems to be the amount of bug catching on the motorway.

Drop round to Eberhart Ltd, Prospect Road, Portsmouth and ask to rummage in their scrap bin.
You should be able to find some suitable sized Polycarb there. You will probably be able to pick it up for free too.

Hi

This is exactly what I am looking to do on my new RIB, this thread is really useful, one thing that is missing though - can you tell me how you fitted it onto the consol - any close up photos would be really useful.

good forum, just bought 4x2 ft sheet 3mm polycarbonate of ebay £20 includes £8 carrage.

Better than the £450 i was quoted for XS screen and metal work, stops yours eyes watering for a fraction of the cost.

Maybe if boat builders priced their stuff a bit more sensibly they would have more work??? Naybe their problem is they outsource too much - it may pay them to learn how to use a tube bender and a TIG......
