Elephant Trunks

Greetings all from a newbie to RIBnet.

I've got a 4m Narwhat that has nothing more than a couple of bungs for drainage on the transom. Trouble is whoever fitted them did so from the wrong side so you have to push the tapered bungs in from outside the boat - fat lot of good that is at 20 knots !!

So, I'd like to try and fit an elephant trunk for drainage and my question is - do any of you know any chandler etc that sells premade elephant trunks. Failing that anyone ever made one and got any suggestions to pass on.

Thanks

Andrew

Do a search; it's been discussed before. Ollyit did it recently on his 4m searider. It's a fairly easy job. All you need is a hole saw, a short length of plastic piping (drainpipe is good), a piece of hypalon, a tube of sikaflex and some cable ties. Drill the hole, glue the pipe in the hole with the sikaflex (possibly glass it in if your worried about water getting into the transom). Then glue your piece of hypalon into a tube, and attach to the drainpipe with cable ties. Chances are it will leak when the boat is a rest. If this is the case put an eyelet in the end of the trunk, and tie a rope from it to a small cleat inside the boat.

Ready made trunks

Andrew

There are ready made trunks around which have a plastic flange which glues / screws onto your transom. This negates the need to drill out your transom/ fit pipes etc. It is a very neat job should take 20 minutes from start to finish.. I think they are available from Henshaw inflatables.

If you cannot find them send me a PM and I will track down a supplier for you.
