that being that the purpose of this design concept was "a cruiser" and
that staying dry is key towards comfortable cruising, that enclosing
the front wall would serve as an effective spray screen. Certainly,
the sponsons would be raising splashes and wind spray while sailing
this boat.

I agree, the only thing I find strange about this design is the flat
front of the superstructure. She's practically a 3/4 size aukland cat
with a different rig and wood floor.
Hats off to Bruce who has built more Bolger boats than anyone.

To me, it combines the best of Bolger's ideas ... ugly when the objective is functional at low cost, and beautiful when esthetics are important. The superstructure is functional, if you don't mind crawling to windward while fighting that godawful windbrake. The rest of the design is gorgeous. Substitute a tent for the box, and you have a beautiful catamaran with a functional dance floor, as Bruce implies.

top priority with this concept cartoon was "cheap home-built cruising

from if you want racing and windward performance. I can think of none
for "cheap home-built cruising", at least where you get this patio
boat with aluminum lawn furniture, plus where you are sheltered and
dry like this. Good cruising definitely requires dry and comfortable
in my book. Sprawling space also is a plus.
Also, while the walls and windows seem huge, putting it in
perspective, I count about 50 sf of windage at a height of 4'3" off
the water versus 280 sf of sail on a 32 foot mast. I place my bet on
the tall sail being stronger than the low deckwall.
