Aaron makes a good point: You need a concrete reason to spend the time and money getting any kind of certification. I have been thinking about getting an OUPV, mainly as something to do, but cannot really think of a legitimate reason to jump through all those ridiculous hoops. What you need to know is how to apply the readily available information, such as lights
, shapes, signals, nav. etc, to actual use. With the flood of internet sources nowadays, if you can't find this info. you probably shouldn't be operating a boat. Most of it is rote memorization, much of it important for ALL boaters to know. You can only internalize what's actually important by sailing. A paper test is great for getting people to cram down facts, many to be forgotten next week unless used, but has limited correlation to overall proficiency on a boat.
