To this I suggest adding a marine emergency strobe light and a stout lockback folding knife.

The strobe is small "D" cell size that can be seen for miles and the knife can be used for
a huge range of tasks that are lifesaving and is all to often overlooked.

Many will poo-poo the knife but ,in truth, nothing can replace a knife as a tool when
you need one. Strong lockbacks, (linerlocks are to unstable in knife newbie hands) from
Camillus, Schrade, or Buck due to their dependable quality. The Camillus & Schrade will
have to be found used ,or on E-bay, as these companies are victims of Chinese imports and
no longer in business.
