Thanks Steve!
Just want to make sure we have easy access in/out. My experiance at Kaanapali Beach club is that the "channel" others have refered to was very easy going out. The intro guide we used had us swim back the same way and the current was really tough to swim against. We were all totally exhausted trying to get back to shore and that really sucked. Have no idea why we were forced to swim back against the rip tide??? I hope to avaid this next time.

Let's talk terminology.
Rip Tide is not a common phenomenon in Hawaii; our position in the deep mid Pacific gives us a very small tidal change so a rip
due to tide usually requires a shallow fringe reef as well as other specific shore and bottom topography.
There are
rip currents in Hawaii, mostly due wave action at the shore. A typical shore rip happens at the postcard crescent shaped beach, where the wide rocky points embrace a long piece of the incoming swell. As it moves into the shallows the swell is compressed lengthwise, causing the wave pushing up on the beach to be thicker out at the ends of the crescent. As the wave pushes up onto the beach most of this water is funneled into the center of the beach, where it all turns due gravity and heads back to sea.
A competitive swimmer or surfer is not able to make headway
against a rip current, even an accomplished free diver is not likely to return to shore
against a rip current. A scuba diver in full dress is like a sail boat in a gale storm, you would just be swept away. The procedure when you are caught in a rip is to swim perpendicular to the current until you are out of the rip,
then head for shore.
The conditions at North Ka'anapali beach are typically a surface current due to wind combined with the in and out surge of waves sliding up and down the non crescent shaped beach. The fact that intro divers managed to swim to shore, on the surface I'm assuming, indicates that no rip was happening. The best procedure in these conditions (surface current) is to come back from the dive with enough air in the tanks to stay submerged until you are in water shallow enough to stand up in.
There is an occasional rip at Black Rock, at the point just past where the kids jump off the rock (South Ka'anapali beach). I believe it is a combination of wind, wave and tide, and it is a very small and confined current, but out of shape tourist snorkelers die there every year. The County of Maui and the Sheraton both know about this danger but neither want the liability from even a strong warning; the sign at the end of the beach access path, over 200 yards from Black Rock, has the typically ignored small warning images of possible dangerous ocean conditions.
Even when obese snow birds are suffering heart failure on the surface, Black Rock intro divers are surviving the minor current 25 feet below.
