Life Cell is a self-contained ditch kit that the owner fills with safety and survival equipment.

It provides flotation for as many as eight adults in the water, depending on the model. It uses built-in flotation, so it won’t sink if it fills with water after it’s opened. The Trailer Boat model, designed for small to midsize boats and one to four people, has a grab handle and webbing lanyards to help survivors hold on. An optional rail-mount bracket is ideal for sailboats. $299 (Trailer Boat). Life Cell Marine Safety, Sunrise, Florida, (954)845-0411. lifecellmarine.com
