Just discoverd a new way to take pics for sailing.
Buy a set of digital binoculars with a memory stick.
You can take photos and shoot movies with them.

Check them out on ebay.. Be aware though the cheap models tend to be binoculars and camera in one unit but they dont use the binocular lens to take the photo they use a wide angle lens in the middle without the fantastic zoom. The more expensive models take pics of exactly what you see throught the eye peice.
