I am a coward so avoid long water crossings.
When unavoidable try to take belts and braces as I dont like the scenario: 'I wish I had taken a dinghy/lifevest/ELT'
Statistics are interesting to ponder over while in your armchair but less than useless when bobbing in the salty stuff. So you have to make up your own mind and live with the consequences.
It does not happen very often but if it happens to you it does.
If you don't buy a lottery ticket as the odds are too small you should not contemplate flying in a SEP over water as the odds are a lot better (worse really) that it will happen to you!
Have fun.
