underdeck pipe fitting

1eyedjim · 31 March 2014, 20:51

as some of you may have seen i am rebuilding an osprey sparrow hawk, i am interested in running all of the cables under the floor to keep it neat and out the way but worried about

what pipe work to use,
how do i keep water out of the pipe
how to seal the pipe to the hull so it doesn't waterlog the foam
and the biggest

best way to install said pipework without removing the floor? is it even possible?

ideally i would like some small pipework from the console to the two pod seats and one large one from the console to the back of the boat for the, hydraulic steering, control cables, engine loom, vhf ariel cable, a frame lighting and anything else i may have forgotten about

if anyone could lend me some info/pictures it would be ace. i will be sinking a fuel tank into the floor so part of the floor will be coming up if this is any help

cheers

Jim

I did it on my tohasu with apiece of conduate i found by some roadworks used for street lights.on my boat would have been inpossible to do without removing the deck as the fuel tank was in the way

Is this foam something you have added?
Make sure that you include a drain hole at the lowest point of the under deck trunking so that water that gets down there can drain into the hull void.

Sure that the hull is foam filled you know, pretty sure of it,
Done an eagle some time back. Check this out,,

I see.
Probably do not want a drain hole into the hull void then

Done work on two eagles and both had foam in the hull,, sure the sparrow hawk will have the same,, all the early builds where done this way. To my knowledge ,

I would chuck a tank in and settle for on top of the deck the cabling

I bought 2 inch flex hose for the searider I am sure there will be a couple of meters spare . so for a Tenner to Macmillan and postage you can have a few mtrs .If you interested I will send you some photos

Not sure now if its 2 inch or 3 inch but will check , ALL I REMEMBER IT WAS 9 POUND A MTR

Yep, that's the sort of thing you're never likely to forget

Compare and contrast this with A1an, our fellow Searider restorer north of the border, who managed to acquire some vacuum cleaner hose from his local recycling centre if I remember correctly...

I don't mind paying for something that seems sensible.

£9/m for Hoover hose is a piss take.

I was that pleased with myself I whipped the hoses off 3 other hoovers last time I was in too.

Il find a use for them.
