That's about right, both fleets had around 33-34 ships.

In reply to the original post, you're mainly right but there are a few points I'd like to make.

1) Ships surrendering was pretty common in fleet actions, and boarding was also used. For example I think three or four ships struck their colours at St. Vincent and one was taken by boarding. Also, while it was rare for ships to sink, some did explode after being set on fire, for example L'Orient at the Nile.

2) Frigates were havily used with the main battles fleets in order to escort merchantmen and destroy commerce. In fleet actions they would act as scout and also stand off the main battle line in order to repeat the Admiral's signals.

3) Battle fleets often had small ships attached to them to act as couriers, relaying messages between the fleet and the Admiralty. There were also used for blockade and escort duties.
