Thank you for your interest in exactEarth. At this time our services are geared more toward Class A tracking of a larger number of vessels as oppose to individual tracking. We do however, have a partner Vesseltracker, that may be able to assist in the tracking of your sailboat. You can visit their website
http://www.vesseltracker.com/en/Home.html to see what they have available
Osea que me remiten a la empresa vesseltracker.
