I have had similar experiences attepting to dive a shallower reef (130ft) in California. After several trips to the site, we noted the times when the current was minimal, and the times when it was ripping. We compared these to local tide tables, and were able to predict when the currents would be divable. To keep your anchor from dragging, you can of course use more (and heavier) chain, and put out more scope. This may allow your anchor to hold, but you'll waste bottom time descending an excessively long anchor line. Good luck! -Tim Bakken > anscott@ma*.ns*.co*.au* wrote: > I'm interested in any ideas as to the best way to anchor or dive this wreck. > It is in 80msw, small, surrounded by reef and prone to huge currents and big > seas.
