Having personal experience now, I agree with Pensacolaracer on this. When you drop anchor the closer to the wreck the better. Have a very heavy anchor, with at least 20 ft of heavy chain. And PLENTY of scope. If you have a windlass, and its not a free drop model, you need to pull off lots of line and open the spool on the windlass to simulate a free drop. The faster you can get that anchor to the bottom the better. The other day, our GPS showed our position 200' away from the wreck we were diving. When we descended down the anchor line, the anchor was resting on the top deck of the wreck. This is why I say you need plenty of scope. First diver down the line's priority at this point is move the anchor into the sand and bury it. We have yet to land squarely on the target, or get lost going to any wreck. Its also MOST important that you know how to use your GPS and depth finder. You need to REALLY know how to use them, otherwise you will have very disappointed divers, and frustrating times. I just graduated from several weeks at Pensacola Racer's Dive Boat School, and I can tell you these were my primary take-aways. Almost forgot one last one, ALWAYS ascend and descend on the line. Even if you have a scooter.
