I fear I am new to this forum, but I hope the following thoughts may be helpful.
So far as usage/battery capacity is concerned, I suspect your usage will be dominated by the use of the autopilot
and the fridge. Nothing else uses significant power, apart from the windlass
, when you will always be running the engines. So far as the fridge is concerned, I can tell you that a L380 I chartered in the Leeward Isles in Jan of this year had a pumped watercooled condenser which was really good. and hardly seemed to use any power. I have since bought my own L380 - don't worry, it really is a great boat - which has the standard aircooled condenser, which in my view is near useless in a hot climate - I cruise
in the Mediterranean
. I would go for a keelcooled or a pumped watercooled condenser. Look at the Frigoboat website. You will find hand steering
the boat to be very tedious. Not for nothing is it referred to as "the tyranny of the wheel"! Calculate the power usage of the autopilot
for the hours you will be sailing - pretty substantial if you are in the trades - So think about the power demands of the autopilot.
You won't need a fitted inverter for the laptop
, phones, and other chargers etc. You can get portable 200w inverters which will do the job perfectly well which will plug
into the 12v socket on the electric
panel. We have fitted a huge 2000w inverter at huge expense mainly so that the ladies can run their hairdryers and straighteners! It has proved itself time and time again!! Keep the ladies happy and you have a totally happy ship on your hands! At a guess, I would wait and see what happens. Boats are unpredictable things. I agree that a couple of 120w(ish) solar panels
on the davits
and a couple of panels on the bimini
roof would be good and may do the job without fiddling about with high power alternators, which may interfere with the warranty on the engines. Wind generator? I'd suggest wait and see if you really need it. They are irritating noisy things. With all those Solar panels, I doubt you will find you need it.
? Just go and get one. You'll need it with all those batteries on board! I would avoid the standard sails
by Incidences. I'd suggest your friendly local sailmaker
. You get what you pay for in sails
. Maybe a good cruising sailmaker
like Doyles. There are still some good sailmakers in the UK.
Do a lot of research
on the watermaker
part of the project
, particularly on the power demands. I'd suggest a 60l/hr setup, either a Shencker if you want a modern low power
system or a Desolater for an agricultural but arguably more robust but high power usage system. Look at the agent system in the area you will be going. You'll need it for spares. You pays your money
and takes your choice!
Hope some of this is helpful
