First Steps and (a few) Questions

Hey all,

I got ASA 101 textbook, and while I'm waiting on that to come in I've just got a few questions. I have some experience in navigation, ROR, and such from the USN, but no experience with sailing. I have some interest for sailing Puget Sound, with anything involving distance being multi-day events of sailing only during the day and stopping to camp at night, but I really don't want something that'll necessitate a car of any scale. So, the question I'm having is...

Are there any rowing dinghies that are light enough to be trailered by hand, but are stable enough for the Puget Sound? I've briefly considered a Scamp, with some form of power dolly to get it from storage near the harbor ramp and off the ramp, but considering the amount of weight for that, the trailer, and the ramp slope (to my understanding, it's the standard angle of 15-20%), I'm less certain on that angle.

Also, as another question, is renaming a boat considered bad luck in this community? The USN has beaten into me that renaming a ship is bad luck, but the rules seem a tad more flexible the smaller you go.

Thanks all in advance.
