SIB Trailer Build

I'm knocking up a trailer for my new SIB, I'll post progress if anyone's interested.

It's a Gemini GRX

The trailer it came on would be ok for local launches but I'm Midlands based and either head north to Scotland or south to Pembrokeshire so I want something that I don't have to worry about.

I'm inventing the trailer as I go along so any good ideas will be appreciated!

It's a bit of an evening and weekend project when I can fit it between real (paying) jobs.

Has anyone had experience of getting an IVA on a trailer from VOSA?


All the best, Jim

It doesn't look like it. If anything it looks like the trailer will weigh more than the boat .

OH MY, and I thought "I" overbuilt stuff. Very nice job!

When I built the upright stanchions for my 4.2m SIB, I used aluminum, and welded up only four of them. Two can be seen in the photo below. I reused the single u-bolts, but what you can't see, is the part that fits into the frame channel to keep it from rocking and carries the actual weight to the trailer.


Nice shop setup for manufacturing large steel objects.

Spot on Nos4r, at the moment it weighs the same as the boat, 100kg


There's a bit more to go on it yet though

That makes sense Peter.

I like your 'transom saver' and I'm messing about with a home made mk1 version. Do you get much side to side movement with it? I was thinking of an A-frame arrangement to try and reduce movement in the leg.

Also would you recommend a short sloping bunk section to help recover the boat onto the main bunks?

I'm trying to work out angles of straps/transom saver at the back end and it's getting crowded.


Cheers, Jim

Couple of the back end.

Two bits of box to support the transom and stop the boat sliding off the back of the trailer. Other pic is mk1 transom saver being invented.
