It is always nice when someone snaps a picture of your boat when you're out cruising and supplies it to you.
You can never get a picture of your own boat out on the water yourself. The odd time you might pull in close to shore somewhere and get a shot of your boat in the water, but it's not quite the same as having an action shot of you boat in motion.
We all like to have pictures of our boats under power out on the water and for that you have to rely on your friends.
TAKE A PICTURE OF YOUR FRIENDS BOATS AND GIVE IT TO THEM
(They'll appreciate it.)
