The ONE thing the entire rib.net community always agrees on is straps never go over tubes. Cheese wire comes to mind.

Not even once. Even for a test..

Can't see what the back straps are attached to on trailer... They point out slightly if the attachment to trailer moves towards vertical the length is shorter so the strap becomes loosened in effect.

You should with enough strength be able to lift the boat and with no separation be lifting the trailer too...

It's the stone age design of boat trailer suspension. If I went over a speed bump with my Ifor Williams which has proper(ish) suspension, it would sound like a train crash in a china shop, so simple rubber suspension stands no chance. Drive it like you don't want to spill a pint!

The bouncing is pretty normal. No shocks on the axle, so the springs cycle til they lose energy. The sound it makes gets worse when you get some rust in the springs (just so you know.)

As someone above said, slowing down helps (assuming it's possible without some jackass in an Audi doesn't hit you.) Also, make sure the tires are properly inflated.

One other thing to check is if the nose of the boat is bouncing relative to the trailer. If so, that calls for a strap to lock it down.

Yeah thats normal. I look in my sideview mirror at times to see the trailer tires airborne with some bumps on the freeway.

Test drove this morning, without the strap on the tube as others have suggested. I still hear a lot of metal clanking when going over bumps. I slowed down to about 15 mph on bumpy neighborhood roads and that helped a little.

One thing I noticed is the transom saver making metal clanking noise when I bounce the stern. How can this be improved?

Also, when I swing the motor side ways it causes a clicking sound in the steering helm (Seastar NFB rack steering). Is this bad? Is there a way to prevent the motor from swaying sideways on the freeway?

Tie steering wheel so motor doesn't move side to side,make sure tyre pressures aren't sky high.

Power T/T? Put a little (or a lot of) down pressure against the transom saver with the trim button.

As to the motor flopping side to side, you'd have to tie either the motor or the steering wheel off to something. A bungie from the wheel to a grab rail, something like that.

When I do that, the frame of the trailer (where the transom saver is attached to) bends a little. Is that OK?

BA, I said a *little* pressure. I wouldn't want to repeatedly flex the metal on the trailer.

Really, the trailer frame bends? I'd say you need to beef that up a bit. Can you post some pics of the trailer (especially the rear crossmember that flexes)?

On my trailer (for an 18' RIB), everything is 4" x 3" (I think) steel box section tubing. No flex there. It is heavy, though.
