Currents can be a concern. Boats should tie off to the buoys, which are secured to the bow and the stern of the wreck. Divers should always descend and ascend along the anchor line to avoid being swept away by the current. A 15' safety stop is mandatory. Due to the variable depths, this should be considered a multi-level dive.
Dive computers are a great aid.
Don't forget your divelight either. Diving the Eagle is an awesome experience. Visibility is often over 100 feet. A large ship originally, the Eagle is an encrusted garden of sealife. Divers should wear protective suits and gloves.
