[Shelter, water, food.Tent, knife, pot, matches.So Tent, as it's instant shelter. Good rest without wasting needed time on figuring out food/water.Spend initial time straight away to use Pot and matches, to distill water from sea. Guaranteed versus maybe finding fresh water.Matches, as I'm not good at making fire from scratch.First day, you are good.Now you have a day or two to figure out the food with the knife and anything else you may find.That first aid kit looks pretty good though, but dropping anything else make it a lot harder
