You get a choice! In Gib, I think at New Harbours, is George Underay. Across the border in Estepona port is a Brit company, SOS that deals with all safety equipment. Don't have the numbers with me unfortunately but they are in the Straits Sailing Handbook. If you are in Marina Bay, see Debs in Albour bookshop and she will sort you out Hope this helps.
SOS Spain (British run, no language problem!) 0034 952 795246
My personal preference is the Estepona contact. They use an English chap, Fred, just a bit more hassle getting it there. George will pick up from any Gib Marina.
Looking forward to our next visit to Gib, got an invite to a birthday party in July!!! /forums/images/graemlins/smile.gif
I used Extinval who were based in Valencia but the local chandlery in Almerimar did the pick up and drop off. I understand that Extinval will do the transport bit if required. Didn't seem costly. PM me if you need more info,
