Anyone know what this boat is and why it has such a big fat boom?

Got an email today from someone trying to identify this boat and why it's boom was so fat. Anyone seen a boom like before? It's featured in the ad below. Anyone know, please add a comment below. There is some blurb in the subtitles that I can't read.

I could find these:

Showing the subtext not to be about the boat but about the watch.

Is it as simple as mainsail storage? No sail cover...and reefing is a bit less messy?

[Adam Turinas]

That was my first thought but as it's a loose-footed main, it looks like it would be very messy.

I have seen boom-furlers before but the main rolls up around the boom as it comes down. This looks like it would roll-up into the boom. With a loose-footed main it would foul-up a lot.

You would need a very tight clange-grommit and fast whirling break.

I know the J-Boats of the thirties had ridiculously wide booms called "Park Avenue Booms". They got that nickname because of a famous photo of a man and woman dressed up walking side by side, holding hands on the boom. They did this I believe so they could put a series of tracks perpendicularly along teh boom allowing them to dial in the airfoil shape at the foot of the sail. Even though this is loose-footed sail in the photo, original sails may not have been set up that way. That is my guess!

I think you might have nailed it.

Thanks

The Americas Cup Boats which raced between 1893 and 1895 were described by some as "The Great Sloops" and others as "rules cheaters" or "freaks" because they had the capabilty to extent their booms well beyond the stern of their boat when the situation warranted it. "The Defender" was a Herresoff designed boat which defended the Cup in this manner. You can see it in a photo with it's boom fully extended in a picture in the book, "Americas Cup 1851 to 1992" by Graphic Arts Center Publishing, Portland Oregon, page 22.ISBN 1-55868-105-1

It appears to me on close examination the boom may be between 2 boom length mahogany boxes that may open to receive the flaked main then are closed around it. Could this be a rich man's early version of lazy jacks?

The theory I heard years ago was that the forces required a strong structure, hence the "beam" type construction. It's light, strong and was designed to create a shelf along the base of the main'sl to direct the airflow-similiar to a deck sweeping genoa.

It is mightily convenient, if you deprive your citizens of political liberties, to portray these as a bourgeois luxury.
