Fishtigua,
Google the M/Y Marlena. Word is she was set to be 124' until the owner found out there was another 124 so he paid about 200K to extend the bow pulpit 2 feet so he could have the world's largest SF. Practical? BTW she mostly fishes for flounder and stripers. Local fishermen use her as a landmark as in : "where you at Joe"--"200 yrds S/E of Marlena" I took a tour of her a few years ago. Behind the main helm (one of 5) there's a 32' TV set used as a chart plotter so the guests can follow.
