Cash,
They are somewhat, still a plaining hull is affected by propeller torque. It is a function of ascending and descending blade caused by pitch attitude, and direction of blade rotation. This is why runaway boats veer off to the left when the helm is unattended (eventually causes helm hard-over).
Are you running a 2 or 3 bladed screw?

Oh by the way, that is with rudder amidships.....if you have very much freeboard, windage may affect the accuracy of your test.

Cash,
Is your PT a single screw? If so, then your turning problem is related to propeller torque. Common on all displacement hull single screw vessels. You can test this at slow (idle) speed by putting it in forward and noting the direction of turn...then put it in reverse and noting direction of backing turn....if it is opposite = torque. I teach new skippers how to u-turn a sailboat in close quarters utilizing this torque (walking the boat).

I am reading the series by Patrick O’Brian that centers around the Royal Navy about Nelson’s time. If you are not up to speed on square rigger terminology, and 1800’s sailor lingo it could be a difficult read. You might recall a movie “Master and Commander” following Capt. Jack Aubrey and Dr. Maturin.

Just a note: I have had good luck using the disposable foam brushes with epoxy and denatured alcohol, thereby eliminating having to pick out stray brush hairs. Foam holds up really good.

I have been doing the same thing....experimenting with airbrushing the final coat with a colored epoxy mix. Too thin, and it tends to run on a vertical surface.....soooo, viscosity and air pressure is the balance to seek. I have to work in my garage, so I suspended operations till the temperature stabilizes above 20C.....cooler than that and it just does not want to adhere and set properly. My test pieces came out beautiful....good durable finish! As it warms I would like to try 5 min. Epoxy.
Good luck!
Good luck!

A simple blade keel with long fishing weights attached to the foot might work. A 90° bend at the hull attachment point, and through mounted to the hull. Fill edges with epoxy. Not scale looking, but functional.

If it is a “loose footed” jib, I don’t think you need the bowsprit....the jib is supposed to overlap the main just a little to create a “slot” that accelerates the air past the leading edge of the mainsail. This produces more “lift” for greater power. Otherwise, rig the jib boom “clew” as close to the mainmast as you can.

This is a ketch rig....the jib (foresail) is self tending, and the “tack” is pivoted to the forestay which appears to be missing. If it is a “full”rig the forestay will will go to the top of the mast...a 3/4 rig will go to just above the spreaders.

The temperature has warmed up, so I have started glassing the hull. I have been experimenting, and have found a way to apply a colored finish much like gelcoat.....but more durable. I will post the procedures in a later post.

I did not like the sails that came with this kit, so I made some new ones with room for hems and a bolt rope while keeping the full size of the sail area. The ladies at the fabric store were very helpful with their terrific ideas, materials, and construction hints. Consult the experts for success!

Cash,
The flux will clean a little as you solder, but it causes the solder to run where ever the flux flows to. A dry surface cleaned with Isopro will help you keep the solder where you want it.....experiment with it, and you will see that it takes less heat and solder for your application.
Another thing that helps is to “shock” your iron tip each time before your next solder application. When it comes up to temperature, wipe the tip on a wet/damp sponge...this removes old flux residue and tired solder...gives you a fresh iron tip for a cleaner joint, and new solder flows smoother. Again, less heat and less solder.

Cash,
I was looking closely at your brass solder joints. Are you cleaning your brass tubing, and solder with isopropyl alcohol before you solder it together? It gets rid of oxidation, and makes a smoother solder joint.
Just a hint...
OW....PT lookin’ good! 👍

Things are moving slow....I am at the fiberglass stage, and without a heated garage it is too cold (-8) to work outside. So I am content to piddling with small stuff. I don’t like the sails that came with the kit, as there is no room for a bolt rope or sail hem. I think I found a fabric store that carries the Dacron I need.

I have the same hearing loss situation (Aviation) you all have, and the mask aggravates trying to communicate. There was a person at the Post Office wearing a clear plastic mask that resolved this problem quite well (ability to lip read). I looked it up, not cheap....but it did work..

I found a way to keep my brass from tarnishing without lacquer.....I just wax it with a polymer auto wax....It seals the surface from oxidation. This works well on gel coats, and polished aluminum.

There is a you-tube posting called “Project Farm”....one of his post is comparing different epoxy types and brands. He is quite subjective in his test, and not sponsored by any manufacturer. Have a look....he is open to test most anything you suggest.

The build on the sloop is going slow. The kit is basically a POS, incomplete instructions, and poor materials. Certainly, what I would NOT expect from Dumas. If this was designed as a beginner kit, forget it! The die cutting is incomplete, and inaccurate. The so-called quality materials are a true extension of the truth, the balsa supplied crumbles when you handle it. Sooooooo……
I have substituted the balsa with basswood, remade several frames from hobby ply, put bolt ropes in the leading edge of the sails so they will rig correctly, and will glass the hull with 3/4oz. fiberglass cloth. It is a good thing I know how to sail, because this helps to understand the vague rigging instructions.
This might make a good beginner boat, but built under the supervision of an experienced modeler.

I found this neat little pond free sail, “Racing Sloop” by Dumas. Decided to build it for my Grandchildren’s enjoyment. Boat specs= LOA- 43cm, Beam- 12.5cm, Depth (waterline to keel bottom)- 7.5cm. The main and jib are boomed for self-tethering. I plan to glass the hull for durability, and probably expanding foam between bulkheads/ frames for flotation.

What temperature setting did you find works best without discoloring the brass? Did you use a silver solder, or just general purpose plumbers solder?
