It's been almost three months since my last post and, as per usual, life has gotten in the way. Work has been the major culprit but the boat hasn't helped. Over the past several months, I've repeatedly reworked the bottom of the sponson transom, to no avail. For some reason, the numbers just didn't work. As frustration started to set in, I went back and looked at the following picture again:
Then it hit me:
I had been laying everything out with the vertical lines parallel to the sponson inside!!!!!
What if the ride pad supports were at 90 degrees to the actual sponson bottom? If that is the case, and the picture above seems to suggest that it is, could it be enough to throw off my work? Since I'm working today in South Seattle, it's only a few miles to the HARM so I'm going to head down after work and see if that's where the problem lies.
