I will use a tiny blower off the pedal drive.  It will need to be spun to get the required pressure but the power demand is low providing the cavities are not spilling air.

The blower on the model produces many times more air than needed but I planned to use it for tests on the pedal boat as well.

Rick,

Never a dull moment!  On the paddle boat, are you going to pump the air in, use a fan or let a venturi do it?

I plan to test at pedal boat level first.  I have decided that is my next project.
