WX man,
Me again!
Dont forget your lifejacket!
...and the dinghy.
...oh yeah, and the flares (no, not the troosers)
...full immersion suit, ELT, GPS, K rations, water etc.
...and a good waterproof novel. You could be there a looooong time WHEN (not if) the engine decides to play silly buggers with you. (may I suggest Tolstoy's War and Peace with the extended introduction?)
You've got a twin rating mate! That's what they're for!
Take care and all the best!
