I think, in this example, you would LEARN that if you're fishing 60ft of water, you might want to try a dropshot. Its not the boaters responability to make sure you know what you're doing. Your job is to oberserve your surroundings, conditions and make a decision on what technique you're going to employ based on that. If 60ft of water screams Lipless crank, you might want to do more research.
As for your question about the two crankbait rods, it depends. Some guys will share; others wont. But I have to say that it takes some BALLS to ask to borrow another angler's rod. That, to me, is showing up unprepared, which I consider a pain. You can always ask, though.
As for your age, I started fishing tournaments when I was 13. You might be sterotyped by some guys, sure. But others will look at your youthfulness as an opportunity to teach you something. We fish tournaments because we want to advance, we want to feel accomplished. DOnt be afraid to ask your boater for tips. They probably rarely get asked and would LOVE the chance to flex some muscle. Makes them feel good and can teach you something.
Side note: DONT UNDERESTIMATE YOURSELF! I've put on some clinics from the back of the boat. Its not uncommon for a coangler to outfish the boater. I've given tips, I've lent tackle. Shoot, a few years ago, after boating my 15th keeper, I cut off my bait and lent it to the boater, who then caught his limit :-)
Positive attitude is KEY!
