I've got same SBS trailer as you, and a similar size rib, Revenger 715 (23ft), rolls on n off trailer with little effort, trailers around 10 years old now, we refurbed it last winter, re-galved the frame, swing beams etc, and added a 3rd swing beam mainly to help when recovering onto the trailer on The Menai, fast currents sometimes! as you mentioned the keel is close to the swing beams try moving the rollers closer together, will lift the hull a bit and may make it move easier, also give all of the rollers a wood spray with a silicone lubricant occasionally, makes a difference

Just spotted this.

Couple of random thoughts:

Have you "serviced" the rollers? They should spin freely by hand. Same for the beams - bolts just nipped tight enough to stop the beams flipping during recovery. I spray thinned grease into my rollers. Lots of semi seized rollers will cause the situation you describe - even with a heavy boat. I had to power the willkcraft off the trailer before I did mine - after one season of corrosion and crud.

My previous trailer was an SBS2000 - very similar to yours. The boat (a Redbay 6.5) always clipped the rear beam on recovery. Despite closing the rollers in it remained an issue. I carpeted the beam and that "solved" the problem. I see a lot of carpeted rear beams in boat parks, so I guess it's a common issue

the rollers the last time i checked (maybe 6 months ago granted) all spun freely as i was looking for a reason you can't push it off the trailer.

my thinking was there simply isn't enough rollers or the ones at the front are pinching the V as it were and causing the issue. i do know for a fact the front swing beam is tight and intend to fix that shortly, only noticed it last time out.

as for the rear beam, i was in clyde outboards other week there and they had a new SBS trailer and an indespension sitting there, the SBS has a MUCH shallower V on the beam which would explain why some end up hitting the beam. i fitted a large roller on the beam to stop it from happening, downside is if you miss it i can't imagine the mess it would make.....hope never to find out! i also made docking poles to help with the issue and i have a keel guard sitting to fit.

this is the result from the way it comes from SBS, it has all been fixed ofcourse but it was a terrible noise to hear first time loading it.

no wonder you weren't happy with the original setup, that looks a real mess

one thing I have noticed with the SBS swing beams is that some beams will rotate more than others due to the length/position on the "stop" on the ends of the swing beam, I swapped mine round so the one which didn't rotate as far went on the front where you don't need as much swing, which left both the rear beams to swing freely for launch/recovery. if the beam is just tight on the pivot backing the nylon nut off half a turn should let it rotate easily

this was another reason to look at going to 6 roller pairs atleast on the back, it should give me enough clearance to avoid the keel ever hitting again, just now i need to aim for an 8" wide roller.

i may just upgrade the back ones and see what happens, i will try to raise the front ones some more, it means drilling new holes in the arm but hey ho, if needs must.

Achieving a state of nirvana aside, is there a reason why you don't just drive off the trailer? Sometimes a rig that needs a wee nudge off can be handy.

i have never tried it with this boat, i have just got used to launching with a bump of the brakes.

i think what i'll do is i'll buy the 6 pair upgrade for the back to help with keel missing the swing beam and i'll raise the front up. i can drill another couple of holes to get the beam up maybe 2", anything else needs new brackets so i'll do that and silicon up everything and loosen off the beams a touch.

Probably not a great help, but here's my roller set up, never lubricated, never touched infact. The only thing that I do religiously is to hose them off quickly after every outing. Boat almost falls off the trailer every time.
