I am a RAW feeder as well. Currently our cruising is limited to a week or less. A week before we go I freeze ice in plastic jugs (I use odwalla containers usually) and I get the chicken etc for the week and freeze it in daily packs, either ziplocked or vacusealed. I take a cooler and pack it as tight as I am able, leaving as few air spaces as possible.
Often I have OUR meat packed in as well ;-)
Over the course of the week I pull the meat I need each day, and towards the end the water
jugs make cool drinking water
, so it all gets put to use.
A more sophisticated way to pack meat for voyages is to get access to a walk in freezer
and freeze a layer of water
with a plastic grid in it, then freeze a layer of meat packed tight and covered with water, then another layer of water with grid, and another layer of meat, up to the top. River rafters use this method and keep meats for over 2 weeks in this way.
For passages longer than 2 weeks I am not sure what you could do. It would depend on the climate, how much refrigerator/freezer space you had aboard, how much meat you needed.
My girl eats between 1 and 2 lbs a day. On a passage
where she is not as active prolly at the lower end. She tends to fast is she is not working out.
One of the advantages of being a raw feeder is that their digestive systems are so much more robust than a kibble fed dog they really have very little trouble with changes to the diet. So if you have to finish a passage
with canned it shouldn't be a problem. The stools wont be quite so tidy and dry but hey you will have a whole ocean to sluice off the deck
I find that when I am on board and out of raw she is very happy with a can of costco chicken or beef. In a pinch she will chow down a bowl of rice cooked in stock (not the liquid kind; what ever dry boullion you prefer). I will be stowing an abundant quantity of both for her and us.
When I lived in Panama
chicken was readily available, as was fish
and beef. Except for VERY remote
areas I suspect that you will be able to find supplies, although what the cost will be will depend on the location.
Just remember to bump up the innards and bones when you get to harbor to make up for the days with mostly muscle!
Good luck and good sailing!
