hi, thanks dronist. the smaller boats seem to go a bit slower than full tilt sport mode.
There are a few bigger boats with huge engines (sometimes 2 of them) that i was not sure i would be able to keep up with but i keep missing them. 1 of the big boats is a tourism adventure speed boat and franky did not think that i would be able to match their pace.
Managed to catch them coming back into the lagoon mouth the other day and tested my mavic against their speed
here is the outcome: check at 1.16 to 1.46
