I remember some pretty good current getting from the dive boat to the wreck. Was not an issue once we were at/in the wreck. Stay close to bottom when heading into the current to cut down on current affect. We were practically crawling along the bottom. Only see one tide listed for entire BVI. BVI Tide Chart

Sorry I just got a kick out of imagining the skipper approaching the mooring buoy (which has it's own foamy wake) in forward gear at 1800 rpm or so, then dropping a regulator to see if there's too much current to dive. :-)

Approaching a mooring at 1800 rpms ?? Hello Well, yeah, if you want to keep up with the buoy in 6 to 9 knots of current. Did you read the whole thread?

Currents and tides are not the same things, although marine and estuarine underwater topography may marry the 2 in a difficult matrimony.
In northern New England, our diurnal tidal difference is 11-18 feet of water. Each tide, in total , roughly 12 hrs. That is from fully high, through low, back to full high. Slack tide is roughly 20 minutes ( more or less depending on where you actually are). Scallop and urchin divers seem to get their quotas every day they are allowed, and their quotas take a heckuva lot longer than 40-60 minutes out of 12 hours.
BVI tide table ( one tide daily) for today indicates that low tide was at 8:23 this morning, High tide will be at 11pm this evening, and the tidal difference is about .14 m, which is less than 6 inches over @15.5 hours.
I think my idea of slack tide is far far different than when referring to the BVI tides.

We dove the Rhône, wreck alley, angelfish reef, playgrounds, WillyT, Blonde Rock and the Fearless. Blonde Rock usually has the worst current.
