To be perfectly honest I have learned more on sailing forums and found far better answers to questions than I have in my very large library of marine related books.
Same here, and aside from having a VariProp and a Honda 2000 on order, we are largely in complete agreement. (You'd like our Lavac head!) I also have a couple of VHF handhelds, one in the "crash box" with the old GPS and flares and heaving line, etc., and I thought I was the only guy using those Swedish (?) hose clamps...
I like Casey, the Pardeys, Beth Leonard, etc., but they are just larger drops in the pool of knowledge. Generally, I find that if I can get five thought processes out of these type of books, they are worth the price of acquiring them (Jimmy Cornell's latest was interesting that way, because he's had three very different boats on circs., and yet has the same general mindset I've already started to develop). Logging in here, however, I generally learn at least one new thing each day...a better average!
