I purchased a wireless lanyard system for my 215 Chaos. It was very simple to install and worked great. Simply clip one of the transmitters (small clip on device and you can have as many on the boat as you want for people or pets) and if someone falls in the water the engine shuts off. There is a "Rescue" mode switch to quickly restart the engine for rescue. I liked the product so much that I added it to our online store.

A product like this makes great sense to me. Especially for someone that fishes alone or likes the freedom to move about the boat working lines.
