That seems to be about what most boats have, although I would say that 2 Hp for every 1000 lb (4 Hp per ton) is more like the upper limit.
10 hp/ton would be considered WAY overpowered by that formula. But I have often been assured of a speedy journey during conditions with adverse currents and no wind, with our 90 hp iron genny pushing 18k lbs.
