It's time to pull the boat for the winter. It's a pontoon style
with aluminum tubes 35' long. Is there a rule of thumb as to
how many blocks to space under the tubes? Do the blocks have to go
under the seams?
The guys at the marina have the attitude that it's your boat. They
will pull it out but you have to take full responsibility.

A really good question to which I do not have an answer though someone will. I have seen those things on dealer lots where they use styrofoam blocks to sit then on. Whether that is to protect the pontoon from deformation or not is beyond me though common sense would tell you that there would be less psi pressure on the pontoon if it were on a 3x3x1 styrofoam block than a 4x4 timber. Good luck.
your pontoons should have "extra support" brackets welded onto the
base and inside edge. ( mine does as well as most I have seen)
Their should be one located near the bow and one near the
stern. This is where the support blocks should be placed.
If you do not find these. I would block in 3 places, 2 feet from
each end, and one in the middle. that will offer plenty of
If the company you are using does the blocking, and is going to
charge you to do this, they should decide on where to block it as
it will be their responsibility if done wrong. If they are
not charging you, that is a different story. If
they want to charge you, and want you to decide on how to block, I
would look for a more experienced company.
