Names of Boat Lines

[Stone]

(Related to Safety Stop Bar thread.)

Below is a picture with some common (dive) boat lines labeled. I'm sure there are regional differences; for example, we tend to call the orange "Float Ball" an "Anchor Ball" because its primary function is to pull the anchor. I don't use a "Descent Line" as shown; I tie the "Granny Line" directly to my stern dive platform.

Labeled names are accurate for Florida. Most don't rig a stern descent line like that though. Generally the weights are skipped with the granny line attached to the anchor/mooring line at the front (generally left floating on surface). Some folks attach the granny to the tag line and let it swing wide, others attach granny to stern corner of the boat, independant of tagline.

Here's a method called the "Carolina rig" that works well but is a hassle to set up: http://www.sportdiverhq.com/uwlinesys.htm . It's much like your picture but designed for larger boats.

My granny line is not much of a hassle (35 ft of nylon rope with a suicide clip for the anchor line and a loop for a stern cleat).

Here's a Catch-22 for using a granny line on a small boat: If the current is strong enough to need one, i.e., swimming 30 feet from the stern to the anchor line wears you out, maybe you shouldn't be diving in those conditions.

Stone,cool.I use hard weights and clip them to anchor and down lines anchor is 20'deep,stern is 10' deep.
