What this video covers

Paul, host of the Isle of Dogs Sea Cadets unit, reports that he, Jack, and Olivia completed a keelboat instructor qualification weekend at the Sea Cadets base at Welsh Harp Lake in West London.0:06 The training was run by Ian and focused on the RS21, a self-righting keelboat that carries four cadets per boat.0:06 The RS21 features an asymmetric spinnaker that accelerates the boat quickly in moderate wind, and an electric engine for maneuvers in calm conditions.0:43 Welsh Harp Lake is compact enough that the spinnaker must come down almost immediately after it goes up to allow room for the next maneuver.0:47 The unit plans to use the boats on booked Monday evenings for seamanship instruction covering sailing, anchoring, and alongside maneuvers, as well as match racing.1:19 Welsh Harp is reachable from Canary Wharf via the Jubilee line and a bus in just over an hour.1:03 The unit also runs dinghy sailing, windsurfing, and kayaking, and is actively recruiting adult volunteers.1:50
