<div>Re: HP per ton – We are now running the big ‘Newt-screws’
(unofficial name) on both the dual and single DeepWorkers.
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?? </div>

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.</font>
