Our fried stopped by to air up his kayak trailer tires and I noticed the ingenious use of pool noodles to add extra cushion to the frame cushions. The setup provides a nice soft ride.

Unfortunately he did not taper the strakes enough so some of the planks came up to the deck at gunnel level. He was convinced to donate the hull and sails to me as a project. I think he got the length and beam exactly right.
I found a broken Dragon mast which I used. I repaired/ replaced some planks (Teredo Navalis damage), fitted new transom, new timbers to support a new keel. I re-cast the lead in a barrel over an open fire to the shape I wanted. She sailed quite nicely.
Exploring woods foreign to me, I ended up with Guango (Saman Rain Tree) for the transom and Mahoe for the timbers, Caribbean Pine for planking. Wood shavings have distinct odours, in this case Guango--strawberry jam, Mahoe --dog poop, Pine-- pine.

PS I got very close to buying "Tin Lizzie". I heard later that she had sunk in Kingston Harbour, Ja.

A gentle reader had questions for our friend Murray about stern shapes...boat sterns... Very good questions. We'll listen in on the conversation...
"Hi Murray,
I’m completely confused. Some of these boats (and ships) look they have two bows, but others seem to have two sterns. So I’ve looked up both “bow” and “stern” in Wikipedia, and my head is spinning with the dozen different kinds of each. The “bow” article explains that the shape has a purpose, namely, to enable the vessel to glide forward efficiently (hydrodynamically, I should say) in the water. The stern doesn’t seem to have a particular purpose that dictates its shape. It has to be designed in conjunction with the rudder, but, in general, it just has to end the boat. In that case, why not make it pointed like a bow? Or a flat transom, like a “regular” stern? Or shaped like a C? It can be anything. In fact, it’s amazing that its shape is so (relatively) consistent given that it could be anything. So I must be wrong. Does the shape of the stern figure into backing or docking? Maneuverability to avoid obstacles or enemy fire? The ship that amazes me in your pictures is the big old sailing ship with two flat ends, two sterns. How did such a vessel make any headway? Why would anyone build such a thing? But underneath the waterline (and just above it), the ship seems to have a pointed bow peeking out, so maybe it’s only the upper part of the ship that is a “rectangular building” sitting on a canoe shape or a rowboat shape. Do you have a favorite shape for sailing? (Is this a silly question? Are sailboats all the same shape?) Very interesting stuff! Teach me about sterns, please."
Murray responds...
I will make my comments, which may or may not be valid. A sharp bow will ride waves better than a flat splashy bow. A transom stern is easier to build than a sharp pointy stern and also allows more stowage room and shorter length of vessel. So a transom stern is more common. A shorter boat costs less to dock. When the builders went to the extreme in the 60's, I started calling them "Sawn-off 50 footers". I thought them ugly with reverse sloping sterns. By "shaped like a C" do you mean a rounded counter stern?
It must be easier to maneuver and dock without long overhangs fore and aft.
The whale sailing ship picture shows the blunt stern but the bow is obstructed from view. The bow though bluff, would be sharper than the stern. I am amazed that those old ships could sail to windward by tacking. But Admiral Lord Nelson apparently said HMS Victory was a good sailer. She is still preserved and looks an awful blunt ended floating fortress. She was sailed there and back to Cape Trafalgar so must have been capable.
How she sailed, I do not know but being long (186 ft), deep in the water (29 ft) and relatively narrow (52ft) must be the explanation. and the rudder is so small, I expect the sails were used to alter course. Her transom is clear of the water. Modern sailboats usually have width 1/3 of length.
As you say, it is the under water shape that matters. Waterline length is a determining factor for speed. Too much stuff above the waterline{ top-hamper} makes for difficulty going against the wind (windage). Victory was a battleship built to carry heavy canons to defeat invading fleets.
As for favourite shape, Usually a pretty boat sails better than an ugly one. I feel I can tell if a boat will sail well just by looking at it. And considering the heritage. However, that may be just my vanity.
I knew these would sail before I set foot in them
This one fooled me. Turned out to be... (edited: porcine in nature)
Shapes and fashions are constantly evolving. Now we are foiling and multihulls and reaching amazing speeds. Many years ago there was a notion that yachts should follow the form of a fish. They called it" Cod's head and Mackerell tail" I built a model C and M which sailed badly. Like others, I found that a sharp bow and an ample beam further aft sailed much better. Another fad was "Plank on edge", being narrow and deep.

As for sterns, I like them clear of the waterline as they have less turbulence and drag. They can be vertical or slopeing transom stern, canoe stern, counter stern, elliptical stern. I think I know a pretty stern when I see one. ( and an ugly one, too)
Doug checks into the conversation with information on the Drascombe Lugger stern design:
"Hi Murray
"Hi Doug,
Having never sailed on a Drascombe, I am curious to know how the rudder, motor well and counter stern all fit together and work. Keeping feet dry is a great accomplishment. Tall wellies also help. How much was the design influenced by the Yorkshire Coble?"
The Uffa Fox Airborne Lifeboats were canoe stern with rudder in a trunk. In 1960's there were a few ABLs on the Tamar. Lovely boats!
Thanks and best wishes, Murray"
I wander by the conversation.

From Bilge Rat:
"Pat was in a small clinker dinghy in the middle of the River Yealm attempting to start the Seagull outboard motor mounted on the transom, it was the old model that ran on 3/4 pint of oil to gallon of petrol, (the reason they last forever) the spark plug had oiled up, so there was no chance of it starting unless the spark plug was removed, cleaned and replaced. Pat Hall didn't have much patience with mechanical devices, especially motors that don't start right away. He became frustrated very quickly, ripped the motor from the transom, threw it into the bilge of the dinghy and gave it a severe kick for good measure. Unfortunately, he was wearing Wellington boots, which offered little protection, resulting in him a breaking his toe. The resulting pain angered him further, so he grabbed the outboard motor and heaved it over the side into 80 feet of salt water, this was the moment he realised there were no oars in the dinghy, meaning he faced a cold swim, or have to hail the ferryman, both options embarrassing for him. Additional to that, the outboard motor now residing in Davy Jones Locker, belonged to someone else."
...to be continued...
...continued...
The Seagull was recovered by a diver a few days later, cleaned, service, tuned and put back into service. Pat got a ribbing or two from the Ferry Captain at the local pub, friendly and measured though, as Pat was a mountain of a man.
Signed,
Doug "Bilge Rat"
Editor's Note: Take the same story, swap out Pat with Cap'. Replace kick with salty pirate language. And instead of Davy Jones locker, trade motor to friend for a Christmas tree.
