After reading the thread about modular kits, I decided to take a similar approach with this project. As part of the larger emerg kit, I made an SOS kit for the boat. It is designed to be small, inconspicuous, float and ALWAYS be on board and accessible, even if the larger kit is removed or inaccessible during an accident.

In a Nalgalene, I included: Fox 40 on lanyard, signal mirror, bic lighter, fire steel and striker, waterproof matches, vaseline cotton balls, fatwood, 2 tealights, microPUR tabs, lrg ziplock bag, bandana, steel fishing leader, fishing line, small pack of hooks and weights, paracord, compass, mini first aid kit (bandaids, prep pads, polysporin and a few OTC meds), lip balm, 3AAA flashlight, chem light, small sierra saw, tea bags and jerky. I put that in an aluminium can and duct taped them together. "SOS" is written in large letters on the duct tape in permanent marker.

This kit will hopefully stay onboard now that our trip is over and will hopefully never be needed. Great ideas all. Thank you!
