Post subject: | Mast Step Ball Question |
Hello: simple question. I am building a 20-foot daysail trimaran and need a ball to use for the mast step. I see Hobie Getaway balls are readily available, and were also used on the Hobie 20/21, so should be up for the task. Does anyone know the diameter of the ball, and VERY IMPORTANT: the thread dimensions of the mount threads. I am in the Philippines, so can't just wander down to the local Hobie dealer and ask questions or view one. To see the boat I am building, visit this thread: http://www.pinoyboats.org/forum/viewtop ... sc&start=0 Thanks guys! |
