Hey Marj, got prob 50+ Dives in on the point. Even dove with ol Chris London there a few times. When I do the drift there, I usually go in at the point 15 minutes after slack or so, sometimes 20, just kinda watch the water and judge it. Usually for me its a 35 min-drift, maybe a bit more, and then usually finish off the dive on the wall at Customs House (Cancat Beach). I've never done it, but I've met a few people who have drifted all the way around from the ferry to Cancat...they drifted over to the lighthouse, got out and switched bottles and then back in. Long dive though, ... I'd think well over an hour, but I've never drifted from the Ferry to the lighthouse.
If you think the point is nice, go out to Black Rock or some of those places if you ever get access to a boat. Even more amazing.
... hope you had a good trip on the Bell Island wrecks too!
Chris
