After getting drenched in a heavy downpour last week and on my way
home, I notice a fellow off to the side of the ICW *walking* his boat
up the waterway. He waves and appears to be in distress so I turn
around to see what's up.

Turns out,

His battery is dead. I hand over my battery booster which doesn't help
much. (Im wondering if I shouldn't have bought a larger one) He then
asks me to tow him to the wildlife ramp. (approx. 3-4 miles)
to which I reluctantly replied ok. He said a couple other guys had stopped
but refused to give him a tow. I have never had to tow anyone but was
willing to help the guy out.

I did irk me that he had no back up of any kind. i.e. extra battery, paddle.
battery booster.

When we got to the ramp, he offered no *thank you* but a "what do I owe
you"?
A thank you would have sufficed, I guess that's what he meant.

Afterwards, I starting thinking about what my obligations are in similar
situations.

I think Im only legally obligated to lend assistance only if it is a dire
situation or
someone is hurt. Maybe someone could clear this up.
