Trailer for SIB , optimal sliding surface?

C-NUMB · 26 July 2010, 21:33

The SIB trailer I sourced today for the bomabard, has as sliding surface made of wood covered by some kind of carpet/fabric. As anyway need to doo some minor modifications to it before usage, would ask, what is considered as the best material for covering the sliding surface, minmizing the friction between it and the PVC hull?

A smooth thick carpet fabric glued on wooden top, would be just fine for a good in/out water sib slide..

just be carefull which carpet you use ,as Loco said thick smooth carpet should be ok
,but some of the cord type carpet can be abrasive after a while especially if it gets sand /grit caught in the pile .

My trailer has phenol coated plywood for the bunks:

Super smooth, and easy to keep clean.

thanks for helpfull comments so far. Here a picture of the trailer. Can't use it now as the bombard is aprox 50 cm kind of to long. However will move the winch forward and extend the gliding surface slightly so think it will will be sorted. The carpet now on the trailer loks like cheapest what ever random material, but might be wrong.

Have some phenol coated(looking the same, weather proof stuff with a kind of hard brown "plastic" like surface) in the garage, might modify using it.

The picture corresponds to a RIB not a proper Sib trailer, unless you modify it to have wider better under tube supports, using it as it is will probably support the fabric floor instead of the under tubes. The fabric looks ok for rib hull issues.

Thats correct, the sliding surface is way to narow for an airflor SIB with plenty of weight on the transom. But this model was the closest enough and should be fairly easy to modify. I wonder should i try to get all weight on the tubes or something also on the floor. The floor is pretty stiff with 0.8 bar( if ever reaching it....).
Funny thing, the trailer its rate for 700/(560net) kg load, weight will never be an issue. Cheers

If you plan to keep engine secured on inflated sib at all times, tubes & transom should be properly supported, is not any good to have supports under fabric, this does not offers digidity as tubes offers, in the long run will ruin under hull fabric.

Both trailer concepts are completely different, each one for it's specified boat application.

This type of bunk trailer modified to your needs, would be perfect for your Aerotec, offers good tube support, has long bow/transom deep V for ease of beach in/out maneouvers.

Thanks, that would be a perfect one. However, think will try to do a semi suitable from bits and pieces thats hope to find in the garage. Intend to keep the boat and trailer only for this season(if things goes as planned) so won't do a huge project of the trailer mod. Will post some pictures when completed, hopefully tomorow.

Thats about what had in the garage, worked ok during sea trial, but need to improve the support below transom, too much weight on the tubes. Small fine-tuning lefto, then it will be ok.

Technicaly the tubes are covering to much of the rear lights visibility of the trailer, but will let it be , so short distance to the sea anyway.

launching with a trailer is so much easier and faster, strongly recomending for anyone having this size of SIB!
