Hi Jon,
The insufficient apparent wind when sailing downwind
is already mentioned. In addition to that my first
cruising-motto is "be as independent as you can get".
This of course also effects the way I want to generate
power. My primary aim is solar cause a) it is
independent of diesel-fuel, b) it's silent and clean
in use and c) I happen to have the room for it.
The investment is costly but I'll have my amps for
free. And what will fuel prices be in the future?
My second motto is "always have another option" so
I'll install an X-Air Marine and a High-Output
alternator. The X-Air Marine is second choice cause I
would choose the DuoGen if I didn't have my gantry.
The former owner already installed a 6 kva
diesel-generator but I hope that will just be a last
resort I'll only use now and then.
In addition to improving my power-generating I'm
looking for ways to lessen the power consumption.
Led-lights (in- and exterior) and extra isolation for
the fridge can provide a big improvement.
And last but not least I want to own batteries that
will last even without attention or maintenance. These
2-volts gel-cells allow depletion to 100% and last for
20 years (this is the suppliers claim). Again
indecently expensive but hey I want to live to be 100
and as a liveabord....
Talking of indepent cruising. I'm always looking for
upgrade on that. I do all maintenance myself,
including the engines, the heater and the electrical
systems. Just started a Ham-course so I hope I'll
understand electronics on a more than my present very
basic level.
I have this Pfaff industrial sewing machine so I can
(emergency-)repair my own sails.
At present I'm taking 2 welding courses (with
certification) and am looking for a tig welding
machine on 220 volts (ok, I admit the diesel generator
is needed for this) so I can make my own (alu-)repairs
and alterations and maybe help a fellow cruiser out or
even earn a buck in a harbour with no professional
welder in sight.
I'm looking for a dive-compressor so I can fill my
bottle myself for underwater maintenance and propellor
clearing.
What do all of you do to get more independent or
self-sufficient?
Greetings,
Len
