Peter,
Enthusiastic helpers,,,hmmm...we have not had a problem but guess that is always a chance of it happening. Guess that is an education thing, but not hard to stop....lots of rope to pull before it goes inside anyway.

The spanner is fixed...can't move in any direction and is sleeved into the mast base....we have found it works for us, and is probably a "throw back" to the A class, again.

Everything leads to the sides of the boat, mast rotation, down haul etc...and both crews are happy with it, after all it is their bits of string.

The saddle is the bottom of youngest's boom vang....still not convinced that it is needed but we have been moving it around to find a simple but easy fixing point.

Will get you pics when boats go back together, winter maintenance and all that, along with 2 new masts coming and other new bits for the other one.....bring on next season...it will be fun

David
