I come from a background of generations of electrical
and electronic engineers.
that, regarding electronics.
We have a beautiful 24 foot lightweight tapered steel keel trailer
sailor. Every year we'd disappear to sea. Just cruising. Every 3 months we'd disappear for 2-4 weeks. Every month we'd cross the gulf here in Adelaide every fortnight or similar.
Gorgeous flat plane, every morning and every half hour we'd routinely obey the weather forecast
. Simply plotting single
tack legs mostly or double the time allowance if wanting to beat uphill to make Kangaroo Island. KI to Outer Harbour was a day due to the running reach. Easy day, simply cruise
Although from bunk, outside silhouette could be seen, we never risked damage yet flooded he'd float.
When laws changed regarding safety equipment
, we halted use and he's sat on a trailer
30 years now, undercover, hard as rock.
Our electronics were basic and adequate. A car stereo connected to mast
stay enabling ABC weather
to be heard loud and clear at Kangaroo Island. Plus lights. LoL. Battery charger
was via outboard
yet wed typically use approximately 10 litres per 2-4 week voyage. Batteries
were gel Cells from the local oil
refinery. 4 had been used to power
entire refinery between Black out and emergency
Genset periods of 15 seconds. Being gelcel they failed high current
dumps but were perfect for just lights and a stereo and at $2 each (recycling price), they gave us some ballast low. Vessel was a 4 man race boat
, 3 men
and a battery
set that sat on keels leading edge balanced.
With lights only use (and every half hour weather reports), we'd engine
every 7-14 days but well before they were down.
Block of ice in a sealed box would last 7-14 days too.
I'll be buying
a 35-45 foot boat
soonish. Although I may not get away without electronics, common sense keeps a plot and believe that some solar panels
and a windmill should be ample. Probability is solo sometimes of multiple days, weeks. Thinking autopilot
looks nice and lots of the used vessels have such. That's about 2kW. Seems expensive to me but I like to sleep too.
Following your query too. I'm lost
How to recharge that during night voyage?
Best I can think of is to sleep during day and utilise windmill, solar
