I have sailed a few small boats in my life but not many. This April I purchased a Margan 250 Class (25') with a trailer. Lunching and hauling the boat is not an issue. The boat also came with a gin pole but no instructions. What is the best way to step the mast when trailering? I plan on leaving the boat in the Duluth Harbor most of the time but also want to take it to Lake of the Woods and a few other large lakes in Minnesota.
