Stretching out a powerboat

Submitted by Matthew on

Design ideas tend to build up around here faster than they can be written down. At the moment, there are seven boats on the board:

  • The Starwind 860 is under construction and her detail drawings are still being finished up.

  • The Bonaventure 570's construction drawings are in work.

  • An up-sized Almaguin (5.8 m) is awaiting final construction drawings.

  • The four Awenda planing-hull designs are on the back burner, waiting for a calm spell.

And after John Harries' post this morning on why long thin boats are cool, I couldn't resist pulling out the CAD models of the Bonaventure 1180 for a bit more detailing.
