SYC Boat Directory

Logged-in SYC members can search the club's boat directory in Members/Boat Directory. Note: this page requires a valid login username and password and is for members only.

Vessel Name Search

In the USA, many vessels are documented with the US Coast Guard and in Canada by Transport Canada. In both cases, the registered vessels tend to be the larger ones. For the USA, go to the NOAA Fisheries Vessel Name Search   For a Canadian flagged vessel, try the Transport Canada Vessel Registration Query System


Radio Call Sign

The APRS (Automatic Position Reporting System) uses the amateur radio call sign of the vessel's operation to locate boats. Enter the vessel's call sign or the ham call sign of the operator.

AIS Location

The functions of the Automatic Identification System (AIS) provide an excellent way to see the underway characteristics of vessels equipped with AIS hardware. Nearly all commercial vessels in the USA have AIS and more and more recreational boat owners are installing consumer-grade AIS systems. More details can be found in Wikipedia and in marine publications.
The two commercial AIS location sites listed below contain advertising and you will be directed off of the SYC website to view them. The SiiTech site appears to have more vessels in it, but coverage for both can be a bit spotty. Also, not AIS-equiped vessels show up in both sites at the same time. But it kind of fun to watch the boats move around. is a company in Vancouver, BC, selling AIS products and services. Their public demo site has more receivers in the Pacific Northwest, although coverage for the eastern end of Johnstone Strait and the upper part of Desolation Sound is lacking. is hosted by the University of the Agean in Greece and has some good features. You can enter your boat's characteristics and photo into the system and send a link to your friends which points their web browsers to your current location. Click on the "Frequently Asked Questions" and the "Services" tabs for more information. A subset of Marine Traffic shows below if you don't want to use the web link at the head of this paragraph. Move your cursor over the map to display the controls. You can scroll the map by pulling the view box in the lower right corner.
