I ran accross this today, and I don't remember ever seeing it posted here before, so I thought I'd throw it out for anyone who wanted/needed it. I thought it was nice that it includes instructions for those who are left with the plan and might be a little worried if they ever have to implement it.
Well, I can't get it to link directly, so if you want to see it, you'll have to click on the link below, then click on "Safe Boating Information" on the left side menu, then on "Float Plan Central"
USCG Auxiliary Float Plan Sorry I couldn't make it more convenient,
