Better if there's a slight "run-down" to the stern so as the boat drains when it's attached to the car but generally you can achieve this by adjusting rollers on the trailer.

So I phoned Indespension today and spoke with their Sales / Technical Dept. No surprise, but the operative I spoke with didn't seem to know either, although did confirm they do fit them !?! His only sensible suggestion was that it gave the keel of the RIB more clearance over the axle.

When my RIB is secure in the trailer there's currently 90mm between keel and axle. However, I don't know how close it gets when being winched on. Currently, there's also no keel roller between the aft swing arm and the for'd set of rollers i.e. I suppose it's possible the bow could dip down and twat the axle as its being winched on / floated off. I'll will definitely remedy this with a keel roller (ordered up already) on the axle for protection even if it doesn't offer any support. Now thinking the spacer bars are gonna stay as well ! After all it works well as is. Still puzzled though !!!

I think I have a slight stern trim on the trailer when coupled up although never given it much thought. Obviously when sitting on the jockey wheel then yes. Must pay more attention !

Trailer axle mounting

It's to do with type approval. The regs have a set height for the hitch and a max angle of the drawbar from that point. I.e it has to be pretty close to horizontal. We fit the 'packer' to meet this criteria. Please come direct to me for any further info. Cheers Jeremy (Indespension Marine Sales Manager - 07825 507471 - marine@indespension.co.uk)

Cheers Jeremy. I played it safe in the end and fitted it back in anyway with the new axle. I like the fact it gives a little more 'under keel clearance' to the unprotected axle beam when launching and recovering. Having said that, I'm fitting some 200mm keel rollers to the axle beam and fwd crossmember for protection only. Better safe than sorry. Thanks for reply.
