The guy should go through a block further forward.
That's what we did this year, with the block positioned at the boat's widest point. But the angle still wasn't very good. In the illustration, if the spin pole is farther forward, the angle is very tight, even with a mid-ship block so a strut is needed. I'm hoping to use the strut to get the guy further out to increase the angle.
From what I read of the 3 recent posts, a strut is still the way to go if the boat is older (as is ours) and a mid-ship block still isn't cutting it. Thanks for the confirmation, guys.
