Boat weights part 2.

Have looked at 12ft tinnies and they seem to weight approx 80kg
(176lb).

At the instantboats.com site there was a boat called a cartopper at
92lb which equals 42kg (more suited to dad than a large 15ft boat).

Feel that a ply boat a little more substantial and thus heavier than
the cartopper is what I am looking for. The lighter the better I
feel. Based on this tinnies appear abuot 50% heavier again than an
equivalent ply boat.

The boat is intended to be powered by my dad's 5hp outboard.
