Thanks for all the pointers, several good items in there to consider.
It will be a few weeks before I get back to the boat, but looks like I'll tackle new rollers at the front, 2 new banks of 8 rollers mounted on the swing cradle (to replace the existing 2 banks of 4 rollers) and then I'll try lowering the rear rollers by one notch, but I'll do one step at a time to check on progress and improvements.
I'm hoping that the new longer roller sets at the back will give the extra length to extend below the transom and help improve launch and recovery.
I have about an inch of adjustment left to move the existing swinging bracket further aft on the trailer, but the extra length and new rollers should help.
Last weekend we had a faultless launch and recovery, so a big part of this is practice and familiarity with the set up.
Launch is improved by rocking the bow of the rib from side to side to ease it off the trailer, rather than trying to physically push it off the trailer.
Recovery benefitted greatly from a few YouTube videos - trailer only into water as far as the rearmost rollers being just submerged, line up rib with trailer a good distance out, approach on tick over and stand in the centre of the boat to balance. Once initially on the trailer, straighten up boat then apply some power to push it onto trailer.
This got us almost all the way on, only had to connect winch for the last couple of inches.
Two more questions!
- what's the issue with the straps round the tubes? I only use them to tow/secure from the slipway to the yard and as soon as we park up i slacken them off again.
- any tips for jacking the boat up off the trailer by a couple inches to replace rollers, without having to remove the boat?!
