Kathryn is a Thames Bawley fishing boat completed by me in 2020. It has detachable keels of different lengths and weights, plus several suits of sails which can be readily changed.
She certainly looks good on the water with all the sail yardage up.
I am going to keep your changeable keel method in mind. That is great for changing wind conditions.

Here are some pictures showing how I arranged the removable keels.
Pic 1 shows the upturned hull with slot ready to accept the keel box.
Pic 2 shows the keel box, wrapped with fibreglass.
Pic 3 shows the keel box in place and
Pic 4 shows it after fibreglassing it into the bottom
Pic 5 shows two keels, the longer one with lead bulb attached, filled and ready for painting. The shorter one shows how the lead bulb can be balanced using the slotted hole. Also you can just see the small bolt used to secure the keel into place. The bottom of the keel box protrudes from the hull to the same depth as the wooden keel and is drilled and tapped to accept this bolt. It has a simple thumb turn on it enabling easy removal or insertion without tools. The keels and bulbs are painted black, but not that portion which goes into the keel box. With the keel removed the boat can be displayed without evidence of a keel.
Pic 6 shows the keel box in situ, braced with struts. The long wooden item is the RC loop 'rack' onto which the winch servo and pulley are mounted. This can be removed from the boat by removing just one screw.
This was an interesting project that required quite a lot of advance planning to get things working OK. I'd be happy to show any other details you might be interested in. 😉
I would like to see how you have arranged to have detachable keels please. Looking for ideas before starting the build of a Mantua Bruma which it is hoped we can convert to also be a sailing version of the motor sailor. Thanks in advance. Cheers Duncan

It's very interesting, as well as beautiful. Are there any videos to see it sailing?
