First what is this BOB suppose to do? I see a lot of shelter equipment. Holland is a very densely populated country. So it's unlikely you can find a private spot somewhere. Not much point in sleeping in front of a goverment shelter, if you can sleep on a matrass with blankets inside.

If you plan on digging (you got gloves) take a FFP2 mask, safety glasses, etc.

- opinel is bad knife for survival, they lock up when wet. A Mora is cheaper and more reliable.

- "50 wind-waterproof matches" no striker mentioned...

- a pink-lady candle... ?

-"lexan fork, spoon, knife". Most hikers and bushcraft people think thats very luxury. Most just carry a spoon or a spork.

-"folding stove and 6 Esbit-tabs" this isn't enough to do serious cooking with your mess kit.

-Beach shelter appears to me, like the kind you have to set up with tent poles and stuff. A tarp will give quicker shelter (if you practised). Since you already have tarp, you could consider ditching the beach shelter.
