Phi, I'd either find another site, or I'd sit this one out. This is an all too common problem with dive planning. You are forced into a screwed up situation because the original plan is blown out. So rather than do the smart thing and abort, diver's try to put a square peg into a round hole. Procedures are there for a reason, they shouldn't be ignored for the sake adjusting a dive site. For example: > > 2. Drift deco not possible (for whatever reason: shipping lane, no chase > boat, etc.). What happens if someone get's blown off??? What was the back up plan??? > > 3. Boat anchor sways so much that a 10-ft Jon line still wouldn't work. > Use your spool and you won't have to worry about this. BTW, I've been in some pretty serious swells and 10' is never been a problem for me. > I am curious as what others would do. And to force a choice between A and B, > let's say you can't deco on deep deco mix (50%) or bottom mix. Are you saying you planned a 70m dive and your only deco gas was 02 in some screwed up fashion??? If you can't deco properly, don't do the dive. Please provide a set of facts so compelling that any diver ( with a half of brain ) would dive to 70m, allowing for this aberation of a deco plan, and not have the proper deco gases. Unless my mother was sitting at the bottom of the ocean there's no way you should allow yourself to be in this position let alone figuring out how to deco at 20' Later -- Send mail for the `techdiver' mailing list to `techdiver@aquanaut.com'.
