A useful sheet says who is in the boat, where you put in, what time you leave, when you expect to be off the water, and who to call if you are not. Phone numbers stay off the free preview so a shared link does not publish them.
The checklist always includes a PFD, a whistle, a paddle, a dry bag, and water. Longer trips add food and a repair kit. Water under 60 F adds a warm layer. Water under 50 F adds a drysuit, gloves, and a tow. Coastal water or a stiff headwind or crosswind adds a VHF and a dry phone. A plan that reaches the edge of daylight adds a headlamp.
The total time is free. $5 prints the sheet and downloads the CSV.
