Ocean River Sports had two Marine kayaks on hand at the MEC Paddlefest at Gyro Beach in Victoria. The Tahe Marine was purchased by Mike Jackson. I got to paddle the boat first at the MEC show then again after Mike had bought it. Click on the title to link to ORS.
There was a second slightly different version the Tahe at the MEC show, but I know nothing about it. The good news is the dealer for western Canada and the USA lives right here in Victoria. He's a semi retired gentleman from Oak Bay.
The other bit of good news is that a slightly larger version of the Tahe Marine is being designed and should be available in the fall. I believe it'll have the same hull but an enlarged deck to accommodate the longer legs and bigger feet of larger paddlers.
Check with Brian Henry about what kayaks he has in stock. As this is such a specialty boat I cannot see him or any retailer bringing in a large number of them.
