I did have a very pleasant conversation with PDG, that cleared things up a bit. Seems a twin engine helicopter will be required which, in return, will make the project prohibitively expensive.
Fuel is available at the destination, its the distance overwater that blocks the use of a (for this project) reasonably priced helicopter.
Looks like I will be rambling my way across in a C182 sweating in survival suit and carrying a raft.
Helicopter would have been perfect, but is not an option.
I thank you for your kind input, it is truly appreciated, though it has been potentially expensive - now I REALLY want a PPL(H)
Best regards,
