I presume that DM's make the group swim with the current on local drift dives for a couple reasons....
1) most divers have terrible buoyancy. If they are swimming...they tend to stay more horizontal keeping their fins off the reef.
2) It tends to make people burn through their gas much faster if they are trying to keep up with the DM.
One big issue we have run into...is when we arw poking around looking at things...and the DM is swimming the whole dive....they have surfaced 1/4-1/2 mile ahead of us. That opens up the possibility of the captain not finding you...getting a ticket for being too far from the dive flag, being run over by a boat not paying attention, etc.
Our solution is diving on smaller 6-pack boats as much as possible...where our group of 4 has much more clout to set the pace.
