Hi Two Stroke Mick
Its an easy question to answer ..so .. In order of priority
Something to quench your thirst .. I find salt sea air makes my throat very dry ..
Some reserve alcohol .. (always carry around a third more than you anticipate.. things can get messy if you donít) and Firewood. ..The fire is the heat and heart of the evening...it helps generate small talk from those sitting around it.
If there are any wummin in the group..carry a wee flask of water..its not everyone that likes roughing it the way I do
Midge nets are essential ..especially if you intend robbing the nearest Off Licence because you misjudged the drinks reserve you carried in for a carry oot.
Food is handy if you are hungry ..but I can survive a number of days on Guinness alone..it is a solid drink..full of vitamins. Make good gravy to help hard horse flavoured burgers slip down easy. A wee stove is handy if you are too hungry to wait for the fire to catch light.
A spade is a must if you like your food..use it to bury the food when your body has finished with..or .. if there is no one watching..to catapult the log out to sea. Personally..I find a carrier bag best when I stick to the Guinness.. as things can get messy for a spade.
If the worst comes to the worst...and it has happened to me ..storm bound for a week .. on a remote island .. some fishing gear can catch a meal.. but if they are not biting..I sometimes have to scoff the bait.
In those situations .. I have found that even a carrier bag is useless the following morning..so stand below high water mark..and just let things go .. but make sure the wind is blowing away from you..or again..things can get messy.. which is not really a problem.. because.. when the tide comes in..it flushes everything clean.
A tent is handy but not mandatory..unless it is raining..or you have plenty to drink. I find a nice Jura Superstition waterproofs my skin against most storms.
In my younger days..I used to find a wummin was quite comfortable to lie on at night..but now Im an old git.. I find I can stay on a lilo a bit longer .. it doesnít squirm around as much so I get a better night sleep.
As for the boat bits .. I seem to get by with what I take...which varies every time..as I tend to forget things.
That should give you some idea though .. as long as you donít forget the most important thing ...which is ..
Where you are and what direction you take to get home again.
