Is it possible to swim off this island

[Homocommando]

Gaps between islands were small when the ice was there... But it wasn't possible to swim (unrealistic I could swim in ice cold water)... Now you can swim but the gaps are larger...

Apparently you can only swim 7 wilderness tiles with 100 swimming skill... But I am not sure how diagonal movement works? Technically I would only have to swim across 3 tiles diagonally NE, and then 2 tiles straight to the north...

Also to me it seems that the fatigue is random... Once I swim 1 tile, get 1% fatigue, once I have to swim many tiles to get 1 fatigue... Weird...

It's not exactly 7 tiles with 100 swimming, it depends on your encumbrance and on your endurance. It will vary from character to character how far you can safely go at 100 swimming.

Yes you can probably make it, if you endurance is good and you're unencumered -- you want to be naked for the attempt, you can come back for your stuff later once you have a raft.. To be sure, Try swimming diagonally from the bottom right of the tile with your shelter, to the tile northeast of it, and then back again. Count how many laps you can do diagonally.

The fatigue increase is not very random - you always get 1% for the first step, but after that it shoud be fairly consistent to 2%, then to 3%, and you will always get the message "you feel moderately fatigued" right at the halfway point -- if you go in a straight line and get to "moderately fatigued", you can turn back and reach the shore safely. 5 tiles is 320 steps, so see if you can do 160 steps before you get to "moderately fatigued" before making the attempt.

[PALU]

You can carry a very small amount of stuff with you.
- You can wear a small amount of clothing for no encumbrance.
- If I remember correctly, you can have an encumbrance of 1 with no penalty compared to 0. I've used that to bring a small amount of stuff with me.

There's only a small window where the water is warm enough not to cool you down, and you can't really afford any cooling when going for a long distance swim. You can do shorter distances when cooled down (assuming you can warm up at the destination), and you can start your swim training (from 0) when the water is quite cold, as you can't stay in for long anyway before getting tired.

The exact point at which you get your tiring percentages is indeed random, but for long distances this averages out. Also note that your range is more random at lower skill levels, as you get swim attempts that won't propel you forward.
