Well I was looking around on Yahoo Answers yesterday and found someone asking the question.
"I'm going on a cruize with my friend, and we don't know what to make a vid of!"
And I answered them with the following.
one of the cool things about boating is that anything can happen at any
time. this however presents a challenge to taping video because:
1. You won't necessarily know when to have the camera on
2. You might not have enough space on your video tape.
3. Your battery might run out of power.
A few months ago I went out on my friends dads boat. And we saw a sea
turtle. I wanted to take a picture of the turtle but didn't have my camera out
to take a pic of it in time.
So a few rules to follow:
1. Action can happen at any time. Have your camera ready to tape.
2. Get extra batteries or if the boat has a power hookup. Get a power
cord.
3. Bring extra storage or video tape.
4. Tape your friends and or family when they are doing something. You never
know when you might catch a classic moment.
I guess to sum up. Just have the video cam on you. make sure you have
enough power for a few hours of taping. And bring enough video tape or video
storage for a few hours of video.You will never know when or where something
interesting will happen that's worth you taping. So just be ready.
