First or last - not the most important. Important is on WHAT kind of craft. In Poland, many sailors are talking, that Atlantic crossing on a RIB is nothing special! Many of them sailed across Atlantic and don't make any fuss about that
The only difference was the craft - BIG or small, but a yacht designed to sail on the ocean, with food, water, and cosy bed
As to electronics - don't trust too much for them!
During my whole voyage I didn't received any weather forecast , not from BBC, not from Deutsche Welle... The EPIRB - one of the best brands, KANNAD, didn't set off, when my boat capsized. On the other hand, becouse of that, I HAD to put the RIB back to the right position and I HAD to sail across Atlantic
VHF, ICOM m15, one of the best hanheld VHF's - broken from the first days! I didn't make single contact with any ship. But I sent a couple of letters in plastic water cans! They are drifting yet, I think, somewhere on the Atlantic
Only the GPS had been working without problems!
Don't trust to eletronic's...
I wish all the best for guys from "Bear Grylls"
I think, that every one, who is trying to do similar thing desrves support all of Us.
