Re: Which boat next?
if you read my first line I want to expand all dimensions in proportion stopping when the headroom reached 6 feet,
nowhere did I say that I wanted to keep the 20' loa.
As to the headroom requirement,having lived in a sailboat 4" shy of full headroom for 6 years fulltime caused back problems.

Well, you change the headroom to 6 feet, but it then would be a much
different boat, with perhaps unforeseen repercussions. (For instance,
with the higher cabin, could you still have vision lines looking
forward from the cockpit while sailing?)
If you need a 'full size liveaboard' 6ft headrom in a 20 foot overall
length, that gets into the 'pushing the envelope' realm. Not that it
isn't inconceivable. The PB&F designs 'Col. HG Hassler', and
Superbrick both do this already. And, believe it or not, the 15'4"
Micro Navigator has about two square feet of standing space tall
enough that my 6ft-0in body can stand up straight enough to pull up my
pants with the cabin hatch closed.
Another way to achieve this standing headroom desire is to use a
tent/awning above the slot top cabin. I don't see any problem with
rigging a simple tarp strung on a rope stretched between the main mast
and mizzen mast of this Chebacco RD to give full length walking
headroom from stem to stern with this design as is.
And, plenty of 'old salts' have argued persuasively that standing
headroom in a boat is much over rated. In all honesty, +99% of the
time while a boat is being used you are voluntarily by choice either
seated or lying down. For the other 1% of the time, the cost of the
necessary compromises is questionable value.

the galley is located outside in the cockpit. The boat is only a 20
ft. They do have a built-in "don't look down" head inside the cuddy
(up against the board trunk), but it achieves headroom through the
cuddy hatch.
reason headroom is a really big deal to a lot of people. I typically
spend several weeks at a time on my Triton in the summer and the only
time I am standing up and walking around is going forward on deck or
after rowing ashore. The time spent moving around in the boat with my
head bent is so small that it is statistically insignificant. If the
boat is rigged so you can sit comfortably at the stove galley area and
reach every thing then the standing head room in the galley becomes less
important.

The Chebacco RD has some other well thought out features that are not immediately apparent.
The cut-out in the keel you noticed is not for a propeller, it is designed to allow the use of a balanced rudder at the end of a full keel. When you turn the balanced rudder the leading edge sticks out into the water flow creating an angled slot between the end of the keel and the rudder blade. Presumably, if this slot is too small, water won't be able to get to the high pressure side of the rudder blade and stalling will result.

Are the oval port-lites a standard chandlery item? EstherMae has two on each side of her cabin and they could stand replacement. My wife insists on keeping the ovals as it certainly lends a lot of character. Unfortunately any production ovals I have seen do not have the same style. The current port-lites on EstherMae are wood, (picture frames perhaps?) the screens and glass that goes in them are flat pieces that slide behind the port-line from the inside with pieces of pie shaped wood to hold then against the interior cabin side. Very seldom do I bother to put in the glass and even at that it almost never rains inside enough to matter, and that is here in south west Florida where we get our share of down-pours.
Bruce, as always I enjoy your rendering of any boat power, sail, or row. Have you had one run through a 3-d plotter?

Deck, and it is another PB&F gem. The writeup is in MAIB Vol.22
No.17. Essentially a cruising upgrade to the older Chebacco design.
Lots of thoughtful detailing, some highlights: 1) Slot top, (with hard
hatches) making the process of stepping the mast more sure. 2) More
headroom in the cabin (raised deck), with well thought out port-lites.
3) Ballasted centerboard, 100lbs of steel sandwiched in plywood. 4)
Mainmast moved forward to improve the helm balance problems of the
earlier Chebacco's 5) Serious built-in
tankage/storage/icebox/batteries-PVpanel(s)/ & toilet appropriate for
a cruiser.

JEWELBOX, BEACHBOAT, 19' X 6', 800 POUNDS EMPTY
Here is a boat that is supposed to be self righting to a great degree without ballast! Jewelbox has the combination proven by Bolger's Birdwatcher of high sides with a thick bottom and low down crew weight to act as ballast. Karl James told me his boat has righted from having its windows totally submerged.... His Jewelbox has been all over the country, including the Mexican trip...
