6) Do people have any recomendations of watermakers or drinkingwater solutions that they may have? What about a solar
1) fine, multiply your water needs per head
by factor 2.5 (esp. so if the other head
is a long blonde hair head), alternative: military cut,
2) avoid big watersacks, if your 200 ltr sack goes (as they do) then you are left with 140 ltrs only (or nothing, if you used the hard tank up first ...)
3) 340 ltrs / 3.4 ltr per day per couple = 100 days at sea, no showers, no laundry
, doing dishes in salt water
4) what about the third one? and how do you get from RSA to Europe
?, add 2 more oceans (AS, and doubling AN, on way back home)
5) get one, use it as your daily water source, keep water in the tanks as your back up, plan energy sources accordingly,
6) people catch rainwater when there is any rain, if they are forced to catch it, it tastes like (censored) and it turns your clothes mouldy, but it will not kill you.
If you are going to use your present boat for this adventure then our experience may give or take match. We sailed in a 26' boat. Similar size, similar challenges. Maybe.
PS If I could afford, I would have had a watermaker. I think I may end up using the small Spectra, e.g. (150/200). Or something alike.
Have fun planning and dreaming. Then sailing.
