Well Sheila, I guess you don`t get much practice at HF in your `Bus,but a few suggestions for your trip...Are you up to date on `dinghy`drill,ever done underwater escape training,your pax.too; you can also put into practice all that ground-school stuff about Crit points, LPD`s,PNR`s ,island holding fuel,and a good `howgozit` chart; don`t forget to wear your immersion suits(not in the bag) as you won`t have time to sort it;spare ELT`s,flares,etc, if the PT6 goes sour(and I`m sure no-one would wish that !).As you are a sailor,take your tide tables,and make a note of the Atlantic sea temperatures.I`d make sure I went `feet-wet` from the nearest land point,only after checking actual consumption against the book..
Also, if you did find yourself `gliding`,put your ELT on immediately,not when you are about to ditch . Take a raincoat for when you arrive,and have a safe trip...honestly !!!
