I'm guessing at most we'd be talking about a couple of hundred quid which is far more agreeable than a couple of thousand! I'm assuming that over time these things will wear out, so there must be somebody making replacements....?

What are the bunks made of if you buy a new bunk-type trailer from Admiral, Dixon Bate etc?

I think the 'mentalists would start to yap and bicker if I flayed a few penguins or seals to upholster my trailer with, but it's an interesting idea

In the short term I can probably grab some cheap carpet and wax it, if the general thought is that this would be a big improvement on conveyor belt 0 what is best then, really el cheapo short fibre stuff? and what do you normally nail it down with?

A couple of hundred? I was thinkinjg more like 30!!! I know that doesn't include shipping but you must be able to find some sort of slippery plastic sheet locally? Failing that as someone else said wood impregnated with grease.

My bunks are carpet covered but there are rubber rollers in the middle . The bunks are much wider apart then yours .

I had a trailer more like yours for another boat and I used to grease the centre bit so the keel slid easily , worked ok for me . I carried a tin of chain lube for motorbikes and just gave it a spray after launching occasionaly.

pengiun has to good Kernow is right there i reckon or maybe seal Jiz

In terms of using lubes like grease or chain lube, what will the long term effect be of mineral oils on the fibreglass hull? I did wonder about grease or something but didn't do it on the basis that I thought it might damage the hull?

Fair point - I just don't want to do it and then find the gelcoat goes all squidgy and falls off.... I've already had enough disintegrating boat problems with the bouncy bit round the outside!

Lots of money....
Depends how resourcefull you are. A couple of pneumatic jockey wheel sized rollers combined with your bunks might just be the job .

Usually only the launch is a problem with bunks. Might be worth an investergation.

If the hull is permanently sitting on grease, I reckon there is bound to be some uptake. Then the day will arrive when you want to do a little gelcoat repair.....

Cod's tanks will not (should not) be normal laminating resin.

What you really need is for the boat to float off then launching will be effortless. Get some smaller road wheels. Tilt the trailer so the rear goes down. Fit the axle above the chassis etc., etc.

Pretty much my thinking on greases etc....

Smaller wheels are on the to-do list, the current ones are 7.50R16 Land Rover wheels/tyres and I have some worn but good Michelin 235/70R16 tyres I apprehended from work to go on, which are a few inches smaller in diameter, about 29" instead of 32", so that'll be an inch and a half less water required straight away just trying to find some cast-off rims at the moment so I can chuck the old ones away, they are pretty scabby!
