as for the lawnmower, i plan to attach a 30 foot articulating sprit to the base of the mast, supported by a boom and truss system tied to the mast head, which allows 360 degree movement using an electric motor and swivel. The "chopper" will automatically engage at the 1 minute gun, clearing a 30 foot circle around my boat, and guaranteeing me a slot to leward at the start. but i'm in touch with RC to see how this will affect my D-pn.
