Trailer for SIB


I am at present looking for a trailer to transport my 4.6m Dykemoor Inflatable. I have approached 2 companies who advertise trailers for this type of boat. Neither have got back to me.

I do have a boat trailer that I can chop about & alter. What I need to know is what design of trailer is required?
I know it needs bunks NOT rollers. Does it need a single bunk on each side or 2 bunks on each side?
Winch or no winch?

If anyone knows where I can find designs for this type of trailer I would be grateful.

I am also considering converting my pesent trailer.

Single bunks per side work. Hit the seam between the floor and tube; that's where the floor is, so you'll be supporting any weight there. Alternatively, support the tubes themselves. Make sure that you also support the transom if you'll be leaving the motor on while towing.

If you plan to launch in salt water, I would strongly recommend a galvanized trailer and not chopping up one you already have. Just pointing this out, you can not safely weld or grind a galvanized trailer without a fresh air system.

I consider a winch a requirement. Plus front and rear tie down point for towing on the road.

Some reading, with pics. I wish my trailer had side bunks, and someday I might add them.

We have a 4.7 metre SIB on a trailer although the boat is being repaired at the moment. When I collect it i'll see if there are any details on the trailer that I can give to you.

This is a modified cheap sib trailer, supports both side tubes, can leave keel fully inflated, includes a long lower transom support at rear if you want engine living mounted on transom, excellent for engine maintenances & towing. This model is for crane use at marinas, can replace small slats for rollers and install a winch to help launch & retrieve sibs faster.

Happy Sibbing

I've seen a similar style done up with aluminum bench seating material (extruded box section about 1" thick, maybe 10 or 12" wide, and whatever length he needed. Aluminum was smooth enough that there was no abrasion and very little drag as teh boat moved along it.

Seemed to work pretty well.
