Some New Brunswick company used to show those at the Halifax Int Boat Show, although I haven't seen their booth the last couple of years.
They were expensive when our $ was only worth 62 cents US. Wonder what they cost now?
About half the cost of an inflatable the same length. Without those
fat tubes, it's a lot roomier, too.
Also needs far less power to plane, so there is a additional big
savings on the engine for it.
