Another one of those threads. And you all are hysterical.
Rick. Look at a map. Yes, the east coast is obviously full of bay and inlets. No, I have never paid more for a slip or mooring. No, I have never been on a waiting list and never found a town without transient slips. I have anchored in 3-5 feet of water many times, when the center of the anchorage was full of monos and most boats had to go elsewhere; there is lots of shallows in the Chesapeake. at least in my area, finger piers are rare; boats are between 4 pilings, and wide slips are reasonably common (I pay $100/mo. for 45 x 20 slip).
Centerline. I sail all winter. Dock queens are about the owner, not the boat. There are both monohulls and cats that are designed to be dock queens!... though I'll admit there are more cats like that. On the other hand, I have cat friends that left home years ago.
Recess. I seriously doubt you could stay with me to windward. 8 knots at 45 degrees (over ground) true is common for me, on autopilot kicking back. I don't pound... ever. While there are cats that don't go to windward, that is a design choice, not a characteristic. Remember, charter cats are built for poor monohull sailors that don't know how to gauge wind (I'm not implying you don't, I'm implying they spec moron-proof boats); many are under canvassed and over-dodgered.
Yes, they are priced high, in some cases too high. On the other hand, they have more room and often more speed, and are best compared to a mono ~ 3-5 feet longer. Some are very high quality, some are not, and the market does not always know the difference. If my PDQ 32/34 was compared to a high quality 36-37, they would be very similar in many regards. I generally find I go to windward with 38- to 40-foot monos.
Yes, there are compromises. The east cost abounds with shallow water. Cats excel at anchor; one deck, open living, no up-and-down the ladder (bad with poor knees). The rig is smaller for the same speed and accommodation, making them physically easier to sail. They have a nasty quick motion in chop. There are 2 engines to maintain (but one is always working!). Although they can handle a blow, seamanship is different and not as well understood (it helps a lot if you learned on a beach cat). You are more likely to be on a bulkhead than between pilings. Capsize is possible, but generally requires multiple blunders. I cruised a 27'/1200 pound performance cat thousands of miles with a 10 year old for crew; we kept her on her feet through prudence, made speed no mono could touch, and went places no keel would dare.
And yet I have no prejudice against monos and would cruise one in a heartbeat. Just different rules and different seamanship.
