This may be a Jerry question. In the SCA interview, Jerry mentioned that the biggest difference between the M-15 and M-17 is the masthead rig. Or words to that effect. My home lake is often devoid of wind during the summer. A genoa would improve things. A genoa with a masthead rig would seem to be a greater improvement. I assume the difference in cost between the two genoa sizes would be slight. I have been thinking about new rigging. I do not think a longer forestay would be that costly. What would be needed to go with a masthead rig, aside from the top casting? Would a second set of shrouds be enough? Are spreaders needed? (Dwyermast.com lists the components on their website for the DM-4 profile.) Could the lower ends attach to the existing hull plates or would a second set be required? Anyone have thought or suggestions? steve Steve R. M-15 #119 Lexington, KY
