The single two thousand footer comes in at just over two tons and has 20 HP (4 X 5HP combined vertical and horizontal) These units can be dialled back to any rating up to a max of 5 HP  -if you want to conserve batteries and don’t need the extra oomph – we’ve also switched to LiOH battery packs. 3 times the duration at half the weight – what’s not to like??

>>> Better a question for Phil, I think. Gamma has 2 hp and weighs 2 tons. PC-12 had a combined 13 hp for 8 tons (10 main plus two horizontal and one vertical maneuvering thruster). The Pisces boats used a pair of 5 hp thrusters for 12-12 tons. So it is beginning to look like about 1 to 1.5 per ton, now that I think about it.
