Well, I have done this, transferring
boats from
Las Palmas to Mallorca. Although, I cooked 2 hot
meals per day, everybody
lost 2-3 Kg! A friend of mine, who sailed the other ship (50")
lost balance and crashed a door from the kitchen lockers.
I was asked to present a High Sea
license to the Spanish authorities.
My friend went directly to
Gibraltar, I went via the cost of Marocco. Going via Marocco means, be prepared for a lot of "Presents", the local habor authorities expect. In Agadir, we had an attempt to steal our life raft at 5 AM, while we were sleeping inside. I can confirm the swell along the coast; in the shallow waters before Casablanca, we were like in a "pater noster elevator".
The regular waves on the Atlantic are higher then the average sailor is used to. You are most of the time close to the
wind coming from NE. There is a high chance that unexperienced crew will thry to make too much hight and drift slowly, than sailing the optimal speed vs hight. Be aware, when you select your crew.

PS: would eventually be interested to do it again.
