nice! I like this a lot!! Here's some food for thought (literally), BTW: I'm a (1 year) "beginner" kayaker who regularly puts on 16-25 mile trips (day/night) multiple days per week on an estuary (Northeast year around).
"Know the nautical rules of the road. The most important rule: Get out of the way. "
Personally I think the rules of the road should be placed in their own section, detailed including knowing port/starboard colors, how to cross the channel, night rules etc.
OR, you could say what you said and include something like get your States/Country's Boating safety guide (usually free) and learn the navigation rules. I would also stress that Kayakers are not really the highest on the pecking order, it's almost a dis-service to think so.
Also, I didn't like the picture of the kayaker who was in my opinion too close to the barge. You may want to talk about the different types of boaters as well, the type of vessel can tell you a lot about the person driving it.
"A bow line, or "painter", can be an important piece of safety equipment in rough water. "
My thoughts on this would be the following (and it's probably overkill): marine people should know some basic knots and carry rope with them, it's easier to tow someone with some distance between you and them then with a short bow line. Also I would recommend a type of rope that floats (polypropylene).http://www.2020site.org/knots/bowlines.htmlhttp://www.animatedknots.com/indexboating.php
Square knot, Bowline (is probably the best), Figure 8 knot (great to keep a line from slipping through a hole), monkey chain (looks cool and can shorten rope and help with tie down to car). This one can be found at animatedknots.com.
'Complacency' should be mentioned
I think this is the most dangerous thing not talked about. That one time you decide not to use the dry suit, or bring your night lights etc. etc. is the time you end up really needing it! I know!
'Log / Diary' should be mentioned
IMO, you should log when you went out and so forth. Also maybe a good time to mention letting others know of your trip plans (float plan").
'Food intake' should be mentioned
I go out with a group sometimes and they pride themselves on making fancy meals and eating it out on a beautiful Island stopping point. It was particularly nice when they had beef stew on a cold wintery day. However, it was not to nice to my stomach (I usually have an iron tummy) but it has reminded me to be safe with what I'm eating. I bring lots of the right types of sports drinks and granola bars; things i've tested and know work well with me. More serious Kayakers may want to know and try to plan bowel movements to some degree.
