Rec boats go up-an-over every wave, not slicing
thru much of anything, while broaching, pearling,
and all to often capsizing due to the large big flat hull bottoms.
It can be physically exhausting controlling the boat.
The big flat hull gets all the force/energy of the wave.
A less wide, slightly elliptical hull, acts more
like a weeble toy - wobbling a lot ,but not going over.
There is a condition where sooo much water fills
the rec boat it becomes essentially like buoy in the water

Water weighs 8 lbs a gallon, lifting anything out of the
water becomes extremely strenuous and needs careful thought.
Float Bags help this issue tremendously,
by keeping the water out to begin with, via pure displacement

Canoeists will do a move called Capistran Flip
basically turning the whole canoe upside down, first,
letting the water fall out and then flip it mid-air.
Takes a bit of practice and is usually done with 2 people.
