SIB Trailer Set Up

[GuyC]

I've recently bought a Extreme 350 trailer for my SIB and I have a question about setting up the trailer in particular the bunks.

Where transversely do the bunks go?

Options are:

In line with the seam between the tubes and the floor;

Underneath the centre of the tubes;

Outboard of the centre of the tubes;

Between the seam and the centre of the tubes.

I've currently set it up for the last option but would appreciate any advice on the bunk positions. For info it is a Zodiac 3.4m inflatable floor.

Hi guy c when I spoke to Ross at Southampton boat show he told me the bunks should be at an angle between the tubes and the floor where the seam is I did have mine in the middle of the tubes but that was very hard work with getting the boat back onto the bunks and launching when I moved the set up to what Ross advised me to I had no problems the boat just slide on and trailer was not as deep in the water hope this helps with it set up HH

personally i dont like my bunks on the floor seam interface i rather have the tube centre on the middle of the bunk so it acts like a shock absorber with a transom plate to hold the engine a mod to this is to put two wheels on the plate to aid recovery and also have a bit of give on the rubber wheels OMO

Hi Jeff I do like your set up with your trailer compared to my bunks

Thanks Ali
IT works for me going to stick some wheels on in case we get the same scenario as Skye instead of the transom pad hopefully

I’ve had the bunks under the tubes and with my futura they are on edge just inside the speed tubes with no problem. But which ever you do it is best to have the transom supported by the bunks or add transom supports.
Especially if the tubes are under inflated over time. The engine can pull on the glue joints. And it’s 24 hours a day 365 days a year pulling on these seams.

I agree with the support on the transom especially if you keep the engine on the back not so much if not

Thanks everyone for all the responses.

I've gone for a half way house between the seam and the centre of the tube.

The trailer has a transom pad.
