That dive boat you passed at 28 knots?
Even though you steered well clear of it, all that really accomplished was
to
increase the time between your passing and the
moment the dive boat began to rock as a result.

Oops, no. A boat wake will dissipate over distance.

Your math on the 2-3 foot waves failed to mention the period and the energy.
As I'm sure you're aware, 2 foot waves can be barely noticed or be quite an
event depending on the period. The energy would also be an important factor.
Wave height alone is insufficient information upon which to base a
conclusion.

I had to take marks off for that, otherwise a good effort. B-
