I agree with Harriet's comments. We are living aboard
prior to making the trip from UK to Eastern Mediterranean
over the summer months. I made a list of all the items I use regularly and am 'experimenting' with various food storage
methods eg baking bread, using the pressure cooker and if we enjoy the meal then it goes onto the next list. It makes provisioning
so much easier and it is surprising how many 'refrigerated items' can be stored elsewhere and still be edible and nutritious a long time later. I was surprised at how much toilet paper we use (mind you it has other uses than the obvious one)!
Last time we went longterm sailing (from South Africa
to the Caribbean) I made a menu plan for 2 weeks and then times it by 4 for staples. We actually stopped off at St Helena, Ascension Island and Fernando do Noronha (off Brazil) so I was able to stock up on fresh veg, eggs etc. I planned the trip on the assumption that we wouldn't be stopping off between South Africa
. Luckily we had lots of fruit juices and sodas because we unsuspectingly filled up with contaminated water
at one place. No watermaker
or ice box in those days!
However, as another contributor mentions there is no real need to stock up with loads of dry goods if you are planning to stop off on the way.
Enjoy your sailing
