Ever since I read the story by Richard Woods and friends sailing his 24 foot Strider catamarans across the Baltic to Russia, I've had a soft spot for these types of small cruising cats. Or perhaps racing cats that could be cruised.
Google didn't turn up anything about Bi Chance so no idea what she is, but assume that she sails fast and has at least some accommodation judging by those side ports.
The reality is you can probably cruise or at least weekend on one of these, but it's more suited to an early 20 something backpacker rather than someone fast approaching retirement. Not that I'm especially included to luxury when it come to boats, but probably wanting something closer to a camper van than a tent these days.
