Hi everyone. The time came to move my new Hunter 27 from Deltaville to Colonial Beach. There were swells of about 2 feet, the wind coming from behind us so I just went along on jib and motor alone doing about 5-6 knots. When I got to the mouth a the Potomac we turned and then had the wind on a beam reach. So I decided it might be time to deploy the Main and see what our speed would do. We deployed it and started running into problems with the sheet catching everything on the Binacle. I was occuppied trying to keep the sheet from ripping off the new GPS from it's mount. So once deployed we turned away from the wind and everything was good for about 5 minutes. The wind picked up and all of a sudden I was being overpowered, cruising at 8 knots per the GPS with no engine. So we decided to point into the wind and retract the main. (Roller furled) Same problem again with the sheet. So we got it in and then we saw this handle laying on the floor. What's that? We realized the sheet had wrapped around the engine throttle and ripped it off! I am not sure if I am doing something wrong or is this a design problem. So we ended up pulling into the Marina at Coan River for repairs.Any thoughts would be appreciated.
