Went down this evening and made this Mod. Jib furles ok (and I lubricated the top swivel) . Now to see how our club users respond to the change. Hopefully they will not notice anything.

Riv.  In answer to your question.  Tape the swivel to cover the split rings.  Split rings always have the potential of getting caught by the spinnaker halyard and being pulled out.  
If leaving the jib up when the boat is not being used, the tensioning lever should be released to avoid straining the boat

I'd talk to RS TBH. I'm sure they know far more about their boat than I do.

I think you want to be a bit careful about rig tension on a rotomould boat. If the forestay isn't sagging too much that would be good enough for me. Similarly with the jib halyard I'd want to use the least tension that gets it setting reasonably. It's not a race boat, so you want to get that last 10% of life out of hull and rig rather than the last 1% of performance.

Jim C, yes, users are tightening up the jib halyard as the luff always seems to be crinkly and it's pulling the jib head too close to the mast and the top furler bearing is jamming I can add quite a bit more rig tensionif you think it's a good idea.

Wyclif, where would I put sticky tape?

How easily does the swivel rotate? Maybe some McLube or other appropriate lubricant?

As Jim C says.  There is also a tensioning lever on the bottom of the forestay to reinforce Jim’s comment.

Might I suggest some sticky tape on the jib roller swivel to make sure it stays together?

We have the same,  I've wondered about moving it up for a better line.  We also have a Sea Cadets unit based on our lake, who have about 6 boats. Obviously all the same, but they don't tend to worry about job tension as racers do.

Have you bunged the photo at RS for comments? The off axis pull of the jib halyard seems intended to make sure the halyard doesn't wrap around the forestay when the jib furls. Make the angle too shallow and that could happen.

[later]

Are you sure users aren't simply over tensioning the jib? The rig tension seems intended to come from the forestay, and the jib halyard only for moderate tension of the luff. Anyone brought up in the traditional way of swinging up the jib halyard as tight as possible maybe needs to rethink.
