Many dive sites in popular dive areas have bullet berths available for submarines. These lake balls provide quick and straightforward access to dive sites and stop damage to anchor switches in sometimes sensitive habitats like coral reefs. However, they require maintenance and are expensive to put in , so not all areas frequented by divers have a mooring system. There are several other ways to secure a submarine over a dive site, counting on the sort of dive site, the weather, and therefore the sort of dive. Traditional docking, embarkation and direct sailing are three differing types of submarines to remain on station when the diver descends.
Many new sailors underestimate the importance of getting the proper amount of 5/16" of chain between the rope and anchor and a sufficient number of ropes within the anchor box. the overall rule is that for each 1" of chain there should be one foot. overall length (LOA) of the essentially make the anchor slide less quickly on the seabed than it's lifted at an angle, greatly increasing the grip and amount of loop needed to carry it without features a certain elasticity that acts as a sort of shock in rough can act for the movement of the useful gizmo for anchored in one place is that the "Carolina Anchor Rig the strict of the sub descends to a minimum of 10 feet, then continues to the anchor line and deepens until it starts at about 20 feet red. this enables divers to dive under large waves once they enter the water. dives and provides a line to tug forward if surface currents are too rough or strong. It also allows divers to opened up and decompress as they surface, or perform safety stops. The last system to avoid problems is that the "anchor ball" return system. Basically, an outsized diameter float is mounted on a steel ring that's fixed round the anchor line. When it comes time to boost anchor, the boat will only pull about 30* from the anchor and therefore the refire the steel ring will pull the anchor perpendicular to the surface because it crosses the road until the anchor is on the surface and the worm is out of the ring. Now a crewman can easily retract the ocean anchor rather than pulling it off the bottom. this is often an excellent system when the sub doesn't have a windlass to try to to the work. the sole drawback to the present recovery system is that it shouldn't be used if it's a wreck or alto relievo reef because the lifting anchors can grind to a halt.
Submarines might need to dock directly above the dive site or anchor very on the brink of the dive site. Anchoring above the location requires the approach of a downdraft/current vessel (usually within the same direction within the Gulf of Mexico). When the boat has arrived in situ, the captain should mark the spot with a pitcher or use a GPS map grid to orientate, then pull 100' to 150' forward within the direction of the wind/current and anchor switches fall when the engine is turned off and therefore the forward thrust is stopped. because the boat floats to the buoy, the rope should be tensioned slowly and slightly to avoid soiling the anchor gear itself. Once the anchor is in situ, multiple lines are often issued to urge closer to the float if necessary. Now the diver simply jumps from the rear of the boat and descends using the lifeline. This method is right for giant, outdated websites. the most drawback of this style is that the diver doesn't have a robust rope to carry on to when coming to a secure stop and must check buoyancy when using the road as a title.
