Could anyone advise me if there is anything available to purchase, or make and fit myself onto the large nuts that bolt the boom through the mast to prevent the kite sheets from snagging on them.
It doesn't happen to me very often but did once cause a swim! It would be one less thing to worry about.
Any ideas welcome,
Thanks, James 

 Hi James,
 
I've seen a few answers to this problem.
From hoops round the front of the mast to taping up.
I drilled diagonal holes through my nuts (not quite as painful as it sounds) and tied bungy through one then round the back of the tack loop and then through the other. It also helps saving the nuts undoing and loosing one when I disassemble.
It works really well for me and I only go swimming when I over-gybe, far to frequent an incidence.

These are my solutions to:
 
 
1 - The dreaded 'lazy-sheet-around-the-frankenstein-bolt' problem
 
 
and
 
 
2 -  The damned 'kite-halyard-wedged-inside-the-kicker-arms' problem.
 
 
Pretty neat I think you will agree ! 
 

 Hello James,
 
I solved the sheet problem by replacing the large nuts with locknuts and washers.  This also solved a corrosion problem I had with the large nuts.
 
All the best

 Hello Chris,
 
I solved the kite haliard problem by changing the washer thickness on the gnav bolts and by sticking fluffy velcro to the inside of the arm where it rubs on the mast.
 
All the best

Thank you everyone for all your help. Some excellent ideas as well as a couple of pics to mull over.
I will sort something this weekend.

I like this solution

Well, that looks like a simple solution.

Not sure if that was cynical?!? This is a slose up:

I meant it. Looks simple and effective.

Hi Guys
The simple solution was me, but the closed cell foam wrapped round the bolts worked well but was cut though by the kite halyard  after a few weeks.  It has been replaced by a shaped pad made of 2 layers of material with mylar film between them, (made by Caws sails), which is held in place by some velcro straps, and has lasted 3 years.   I have also used a 20mm strip on mylar  to keep the kite sheet out of the gnav bars. This is taped on to the gnav bar either side of the bolt for the roller on the kite halyard and stick on velcro is used to attach it to the gnav bar on the port side.  This also enables me to hold the main halyard between the gnav bars and it is easy to remove the boom.
I also have made up little clips along side the shroud plates from mylar which helps to hold the sheets up in conjuction with the elastic sheet tidies.
I will get some pics and post them soon 

Some pictures would be great.
Thanks,
James

Hi James

Mark, that is very very kind of you. I will show these to Mr Goacher and get him to make something similar.
Thanks so much,
James
