Loyola Pomroy of Island Rendezvous , Woody Island Newfoundland has
large pontoons on a floating wharf that would be ideal for you. That
floats a dock and can be used as a barge to carry about 40 kayaks when
the weather gets "BAD!!"
Loyola is a good fellow to talk to as well.
He is brilliant at this stuff.
If you search Island rendezvous or Woody Island Resort you should find
them.
