Wow! Great stuff. Keep 'em coming!

On tunes - We bring an RF modulator for our iPhone so we can get signals into the boat's music system. Most systems these days have a 3mm or 1/8" aux input jack, but every system we've seen has a FM tuner.

Picking up a mooring - Don't hook the loop! If you do, and the boat starts drifting back and the line gets taught you can be forced into the choice of getting pulled overboard or letting the boat hook go overboard. Hook the mooring pennant behind the loop. We went swimming for the boat hook a time or two before learning this lesson.
