M_Boats: forestay

I want to install CDI roller furling on my M-15. My question is. Since I have to change the forestay to a turnbuckle arrangement plus buy a new sail, would it be advisable to go to a Masthead configuration since I live in an area of light winds most of the year? This is the second time I have posted this with no responses. Does anyone have Dave Scobies email? Also: I have a 2012 Honda 2hp longshaft OB for sale. Charles Hill 865-438-0600 chsail36@aol.com
