Byte 5:1 mainsheet

A faaaarrr smaller diameter!  I used 7mm on the 600 and same again now on the musto.  Fat sheets dont ease smoothly enough for my liking.

I will have a look and get back to you!!!

When i first started to sail a Byte I went for a 3:1 with a decent rachet block and after a couple of heavy wind sessions I went up to a 4:1.  The loads seemed remarkably high with a 3:1 so I can see why a smaller Bytist might want a 5
1.  Mind you I was using thin rooster main sheet which means your working hard to grip the mainsheet.  However I wouldn't go fo a 10+mm mainsheet as it'll take to long to get in and out.  I'd use somewhere between 6-8mm depending on your arm strength.  Don't worry too much about having too much rope, the distance between the blocks and the boom at its max out point is pretty short (hence the need for a high purchase).  I'd guess the you'd need about 10m at most for a 5:!.

As for the mainsheet swivel jammer.....bin it, bin it now!! Repace it with a rachet block on a spring, you may even be able to recycle the block on the jammer if its a functioning rachet!  Then put a jammer cleat on each side just aft of the traveller cleats. Any other questions just PM me.
