The STG EMERGENCY HEAVING LINE consists of 75' of braided UV-inhibited floating line. The line is bright yellow, making it easy to spot and keep clear of things like moving propellers. There is a snap shackle about 3' from the end of the line and a loop on the bottom of the bag. For best distance and accuracy the HEAVING LINE should be thrown underhanded. The person in the water should bring the bag around his/her body and fasten the snap shackle to the loop on the bottom of the bag. A stainless steel bracket for mounting on stanchions or bulkheads is available.
