Sorry...but relatives die, move, get angry with all the crap they have to manage for you. St. Bredan's Isle has been doing this nearly 20 years and as they say:
" We have been providing mail forwarding services
since 1988. As the largest mail forwarding company serving Cruisers, our mail service has been recognized by the Seven Seas Cruising Association with their prestigious "Highly Rated" Designation. "
Anything the SSCA rates highly is a PROVEN service in the WORLD-wide cruising community. Lots more reliable than relatives!
