Thanks to you all, some very interesting and useful information. I was aware that the halyard winch needed to be hinged to allow the mast to be lowered but didn't know how until I saw a detailed picture on one of the web sites recommended by a3nige. The photo from deadbeat also shows the rigging very clearly. If you could, please Andrew, dig out the article which appeared in a back issue of the MB magazine it would be great. I suspect that the plan is the same as I will need to blow up the plan I have by 2 to produce a boat with an overall length of 30" (1/2" : 12" scale) I have looked through some of the back issues on the MB site but can't find the article. When I eventually get going I will keep the thread updated. The summer is for sailing not being stuck in the garage!
