hi, 2 questions about pontoons: This is 1st winter for my pontoon and am trying to decide on winter storage options. I was thinking of pulling the boat onto shore for the winter. It is a sandy shore with about a 10% grade. Many of my neighbors use PVC pipes under the pontoons and a winch to pull it up. I was wondering if this is a good idea, and how much winch will I need for a boat that ways about 2k lb's. 2nd separate question is weather a 10'x4' aluminum dock can be used for mooring. I'm worried that the boat might pull the dock off along with it in high winds. The lake is mostly calm with no more that 6" of swells, except for boat wakes. Thx.
