Amused
I get a kick out of the speculative comments in this thread.
The boat sunk because the owner failed to maintain her and was out in weather for which he was ill prepared. As noted above, an 8d battery was not properly tied down and broke loose in heavy seas, hitting the stuffing box and allowing the engine room to fill with water.
I know of very few boars that will not founder once filled with water. The fact that this boat sunk rests with the owner, not the designer not the builder.
The CG is about 5 feet above the waterline - not as low as a ballasted sail boat but at a similar relative height as a container ship.
Computer studies show that she is self righting from a 100 degree knockdown - this assumes the windows are not stove in (not a realistic assumption).
The Moment of Enertia is closer to that of a catamaran than a typical displacement trawler - this means she rolls less and it takes more energy to make her roll.
Regarding windage: with her widely spaced props, she can rotate in her own length. With a displacement exceeding 100,000 #, she is not easily affected by wind. She will heel about 1 degree while motoring in a 20 knot cross wind. Maneuvering in 20 knots takes some planning and skill - no thruster is necessary for the experienced skipper.
I find the story of a helm chair falling out of the pilot house and over a 42" high rail hard to believe.
The Florida Bay Coasters handle typical cruising conditions with aplomb, both in the ICW, Great Lakes, coastal U.S., and the Bahamas. Yes, they are coastal cruisers meant to be used intelligently inland and coastwise. No claim has ever been made that they are all-weather, go any where yachts.
Yesterday I had the opportunity to drive a sister Coaster, Irish Rover, from Kent Island to Edgewater, MD. With gale warnings flying, I chose to stay ashore.
I built the Florida Bay Coasters 25 years ago - most have given their owners the experiences they expected - delightful living aboard with cruises up and down the sea board.
