Noonsite users may be familiar with Yellowbricks from offshore rallies they have participated in, but you might not be aware you can buy a Yellowbrick for your own personal use.
Yellowbrick is not an EPIRB or a PLB; it does not just transmit your position in an emergency, it transmits your position on a regular basis, all the time. Friends and family can see where you are, and where you have been, on your personal web-based map. It is waterproof, rugged, and trusted by virtually all the world's major offshore yachting events.
Yellowbrick is battery powered, and will run for up to 3 months, transmitting hourly. In standby mode it will last for up to a year between charges. It can send and receive short messages via e-mail and SMS, and has an alert button. Running costs are just £8 (US$12) per month plus transmissions, and you only pay when it is being used – you pay nothing when it is not!
Why wait for an emergency to let people know where you are?
