boats and planes

Posted on by

At 1230hrs PDT a vessel (13K 116013) was observed entering the Reserve under high speed from the west. Within 100 metres of Great Race, the vessel slowed, passed near Rosedale Reef, then turned around and sped back out to the west under high power.

Mid-afternoon, a vessel was spotted drifting into the NW side of the Reserve while fishing. The vessel departed after about 10 minutes.

At ~1515hrs PDT a red eco-tour zodiac (company name not visible) transited the main channel from E to W at a speed greater than 7 knots and fast enough to keep the vessel up on a plane.

At 1533hrs PDT a floatplane passed from E to W over the north side of the Reserve.

At ~1600hrs PDT a whale watching vessel approached closer than 100 metres to a California sea lion hauled out near the derrick. The vessel was actually within the kelp bed off the rocks. Upon sighting me [Adam] the vessel backed off and sped through the main channel to the west. After passing between West Race and Middle Race, the vessel throttled up well within the limits of the Reserve.

Orcas again

Mid-morning (exact time n/r) a small aluminum vessel with 4 persons on board entered the main channel and transited W to E to the NE corner of Great Race at which point they proceeded to throttle up, maneuver around the kelp beds and out of the Reserve.
At 1350hrs PDT an aluminum vessel with 4 persons on board was spotted fishing in a line drawn directly westward from North Race. A license number was not recorded.
At 1357hrs PDT a vessel was spotted transiting the west side of the Reserve at high speed (14K 27490).
At 1357hrs PDT a fibreglass vessel (WN 0516 NH) was spotted fishing on the W side of Great Race within the limits of the RCA. This incident was reported to the DFO Fisheries Violation Reporting Hotline.
Ecotour infractionAt 1425hrs PDT a pod of orcas passed over Rosedale Reef from E to W. A whale watching boat(red/orange RHIB, name not visible)previously outside the Reserve and following the whales, approached within 100 metres of the pod and followed the whales into the Reserve. As the whales passed through the Reserve, the vessel headed south towards the green buoy but ultimately passed on the Reserve side of the buoy. This action is in violation of the PWWA guidelines stating that eco-tour vessel operators must not follow whales into the Reserve. Photos of the incident were taken.
At 1430hrs PDT, Chris, Garry, Andrew and son, two photographers and an employee from the Development Office arrived at RR for a tour/meeting.


There were 7 visitors to the island today.

At 1000hrs PDT the United States Coast Guard Cutter Swordfish entered the E side of the Reserve and approached Great Race. A launch boat with three persons on board was deployed and began to maneuver carelessly and at excessive speed along the E and SE side of Great Race and over Rosedale Reef. VHF contact with the captain of the USCG Cutter Swordfish was made and the vessel left shortly thereafter.
