1. Yes
2. At least one variation of all but the latest rigid hull (but looking).
3. My favorites are:
a. 101S-Chesapeake (toured in Baltimore)
b. 110S-44' Motor Lifeboat (looks like replica in Maritime Museum in Astoria)
c. 104S-Skipjack Nancy (just like the design)
d. All the others because they are well done.

I started out with the intention of only collecting AB lightships as a nice supplement to my lighthouses. I purchased the "nonlightships" working boats when they came on the market at big discounts when they were discontinued. Then came the Coast Guard boats, and by then I was hooked on AB boats.
