[PSUBS-MAILIST] Surface Transit and power requirements

[Alan James]

Hi Joe,
if you are meaning that your generator is removed for the dive & left
floating on the surface, then wouldn't it be easier & more economical
to have a small inflatable with an outboard motor ( which is designed for 
the environment), to tow the sub.
Or a straight outboard motor instead of a generator on the sub.
Could be hard going removing a generator or motor & attaching again
in poor conditions.
Alan

I have a
question on my mind that I’d like to pose for ideas. It concerns primary
propulsion and the potential use of an electric golf cart motor for long
distance surface transit say in the order of 4 to 5 miles one way.
 
What I am
thinking is the use of a motor pod ahead of a moveable rudder Delta style. If
one were to use say a 5hp motor where 2-3 hp is required, wouldn’t the larger
motor be less taxed and run cooler, turn a larger prop,  be more reliable long term, etc?
As for power
drain, what if a portable Honda generator could ride temporarily on deck behind
the sail in a purpose built ventilated enclosure that is quick release removable.
Could this not be connected to a purpose built electrical thru hull feeding the
main bus?
My goals
here are simple.
1)      The ability to travel to relative distant
dive sites with relative ease
2)      Reducing a surface support
requirement to a small semi-rigid inflatable.
3)      The ability to satisfy power drain
and on site recharge capability without rafting at sea.
4)      Eliminating the complexity and costs
associated with inboard diesel propulsion.
Ideas /
thoughts?
Joe
