We have developed a PC based program for teaching docking which
simulates the physics of different boats, the current and wind and
their interactions.

This has proved very useful in teaching my crew, and surprisingly, me
some useful principles, and allows risk free practice that has improved
my boating safety.

For a demo copy, contact me by email. If you like it, I'll unlock it
for a small fee, $29.95. If not, I'd like your comments anyway.
