Bit impressed by the woodworking skills here ...was fueling the whale boat and snapped a few shots while waiting...
No idea of the design.....! The dark side side in me can only imagine the maintenance that will be required ...
The design in probably a Colin Archer, an interesting man born in Norway and lived in Queensland.
