Just think of the untimate floating paddling/fishing platform- the SOT kayak.
For the record, the plastic sots that are so popular now, can,will and have, infact, sunk when filled with water. This is why everybody recommends filling the hull with pool noodles.
These pigs of plastic are far from the ulitimate in anything - least of all as paddling machines. About the best thing that can be said about most of them is that they float. :lol:
