Lots of new things! You're working really hard on this and I want you to know that I notice it.
The sextant is too complex. It's also a very old type of device. Less than 1% of boaters even know what it is for. We want to be much more modern than that.
The prop is a problem symbol because of sailors and sailboats. I hunted around for different symbols and tried to find someone who handled that type of thing (sailboats vs motorboats). Most logos stay away from the issue (or lean toward sailing and the wind). Here's one that tried to balance it:
http://www.yachthavens.com/We had a long discussion here this morning about the logo, etc. We're thinking that I gave some bad direction with the whole "guidebook" thing. It's making logos that are getting too complex and not very nautical looking.
Of your designs, #30 is the one we still like best - we keep coming back to it. Perhaps that should be developed a little more. Maybe a little more abstract - font changes, etc.
I also hate that all I seem to do is show what I don't like. So in searching around, we came across some logos that we like a lot. They all involved waves and the ocean (like your #30). Here are some icons that we absolutely love:

I'm not sure if giving examples like that is a good thing or not. I'm new at this! Please let me know what types of feedback you need and I'll try to be responsive.
