A coastal/offshore powerboat safety kit: flotation, signaling, communications, dewatering, and repair for when things go wrong miles from shore — organized so the critical items are grab-and-go.
Scenario: Ten miles out, the engine dies in a building chop and water is coming aboard faster than you like. Cell bars are gone. You need to hail help, stay afloat and visible, and keep the boat dry enough to stay with it until the Coast Guard or a good Samaritan arrives.
The safety and self-rescue essentials for a day of flatwater or coastal kayaking: flotation, dewatering, signaling, navigation, and the dry-stored basics that turn a capsize into an inconvenience.
Scenario: A calm morning paddle turns into an afternoon of wind and whitecaps a mile from the launch. You take a wave wrong and go over. Getting back in the boat, pumping it out, and reorienting toward shore all depend on what you clipped to the deck before you left.
