Ive done this and found it a bit too salty to use onky seawater. Maybe using 50/50 might be ok

Some things that come to mind that don't need a fridge

Unwashed Potatoes (never been in a cold room)
Onions
Garlic
Ginger
Rice
Pasta
Longline Milk or Soy Milk
Canes of Coconut Milk (Great for nocking up curries)
Longlife Thickened Cream (comes in small Cartons)
Mixed Fruit (Peaches & Pears) goes great with Long life Cream
"Stagg" canned food, Various types of Chilli Mixes (sold at Woolworths)
Bake Beans
Spagetti
Muesli
Oats
Process Cheese (wrapped in Foils) yes it still exists
VitaWheat, Salada and other types of
Olives
Sundries Tomatos
Fresh Farm eggs (never been in a cold room if you can get them
Apples
Lemons
Lollies

As far as using saltwater for cooking, try it before you leave shore. I'd recommend carrying an extra 20L of fresh water. As a matter of fact below is a complete list of my ship stores. Where it says dog food, this covers things like the above mentioned "Stagg'

If you find the right salt/fresh water mix and cook, say. pasta in it, can you retain the used
water and cook another pasta the next day. Or is the water now 'yuk'. ??.

Add decent quality parmesan cheese - it's good for a couple of weeks unrefrigerated if stored down where it's cool. The Coles fruitcakes also keep for a surprisingly long time out of the fridge. Mixed nuts and dried fruit (Scroggins to the oldies, or trail-mix to the Hollywood-affected) makes great high-energy snacking material that you can fuel you for ages on when it's blowing like $%& out there.

Garlic flakes are great for easy tasty pasta's etc. Canned tuna or salmon, when added to pasts with good quality oilive oil, garlic flakes and a touch of chili flakes, makes a fabulous quick & easy high carb & protein meal that you can gobble cold for lunch on the go the next day.

I found the salt/fresh water ratio to be about 25 or 30% max.
Egg-sucking time.......observe the usual caveats around using salt water in harbour, near other anchored boats, or after someone's used the heads!

I was thinking of water conservation of course for those of us that have limited
fresh water tankage and no water maker. But as you say, you can't use 'yuk' water.
Another thought re canned food. If you are in tropical climes (FNQ) for instance, do you
keep your canned food low down against the hull below waterline to keep them relatively
cool, or doesn't it really matter.??.

Doesn't really matter where you keep them. Keep them dry to prevent rust on the cans, remove all paper labels and glue from the cans as the creepy crawlies love to eat that stuff and you don't really want to encourage them. Having removed the label from one can, remember to write on it with waterproof texta, what is in it.
If any can shows signs of swelling, dump it, the same applies to glass jars with the 'magic button' on the lid if it clicks when pushed.

Don't forget the smoked meats they last and add protein to your diet, and you might like to grow some sprouts, depending on the amount of time your trip is likely to take, these will give you your vitamin C and don't take up much room and add something fresh on extended trips. (alphalfa, bean, lentil, red clover, etc.)

Excellent idea Graeme
Cheers Greg

They are pretty robust actually. We used to use them for camping and they'd last a quite a few trips. One that I still use has a slight leak that loses about 1/2 litre a day, but can be forgiven as it's over 10 years old!

Obviously you have to pad inside the locker against screws or protrusions etc. Worst case is a bit of a dribble into the bilge and you lose the odd litre, and use the leaky one first.

Keep your eye out for the specials - $20-ish.

Cheers, Graeme

Sprouts are good. Use to grow them when cruising. Brought one of these. Very simple to use

A cryovac machine aboard is a great way to make things last longer. Catch a big fish and make meal size portions, cryovac each portion and they will last 2-3 weeks in the fridge easy as opposed to 2-3 days. Also precooked meals last 2-3 weeks.
I use a 30-70ish salt/fresh mix for spuds, pasta, rice etc.

When this finally comes out it will make me pretty much water independant. 15l per days capacity. I funded the kickstarter over a year ago now, theres been some delays but still hoping to receive mine in the next few months.

So you put salt water in and get 15lts of fresh water out. It says it doesn't use filters
so where does the extruded salt go ???.
Looks like a great idea. As you say, it would make a single hander water independent. Marvellous.
