Thanks for the information, it's very helpful.
I think I'll be drinking even more tea than I anticipated (at under £0.02p a cup - I'm taking 1,000+ teabags with me when I go for the boat to get me started, lol), less coffee, and a lot less alcohol (I don't drink much anyway, but had planned to optimise the health
benefits better by drinking a fair bit more), and my plan to mainly anchor
out (involving more investment in ground tackle) at every opportunity, that sort of thing, along with going for a smaller boat (32ft), plus single
handing, should help a lot.
If CopperCoat does what it should, and helps prevent haulouts for 10 years, I'll be really happy.
The nice surprise was how reasonable (to me anyway) the boat maintenance
and upgrade costs were, and for a 40ft at that!
