Best way of using Sailwave for our regatta

Hi everyone,
I'm intending to use Sailwave for our regatta at the end of August -
having been using it for our ongoing series with great success.

On the regatta day, we will have one race per fleet, with one-design
fleets and handicap fleets. One complication is that within a
handicap fleet, if there are sufficient of a particular class, then
they get their own prize.

What is the best way of handling this in Sailwave? I'm assuming
that we should set up a Sailwave series per real fleet, and set up a
Sailwave fleet within each real one to handle the classes which
qualify for their own prizes.

Any input/tips would be appreciated!
