After recent water trials, it was determined that the boat needed the Center board lowered. Added the design from drawings and the photo from actual boat, plus some lead added in a hollowed out area of the new I will do another water test soon.
Any suggestions for creating a water tight seal? I am using clear hockey tape around the cabin roof which seems to keep water out, but over the open cockpit is where I am placing a cover which is suppose to keep water out of this area. I also poured polyurethane on the floorboards of the cockpit to provide a good seal and caulked the seams too.
[Score: 9/10] 25" Catharine - Comments: Uses 4 AA batteries to power the Spektrum Receiver and two servos. Mast is 22” Boom 20” Sail material is from Doyle Sailmakers Inc. 2.2oz Fibrermax nylon from Challenge Sailcloth Draft is 3” Bean 8”
12 degrees according to this PDF but I may need to go a bit less say between 8 & 10. These photos give an idea of where I am going with these modifications. The prop shaft is too steep in this photo...
This is a Norstar Kingfisher design. I want to place the motor beneath the rear hatch where the batteries sat. The CG was far to forward and this is a heavy model so it never ran very well. the motors ran hot even with a water jacket. I am moving the motor back, using a shortened prop shaft ,but what shaft angle will produce the optimum performance? Ron
So you say, “What is new?” Doyle Sailmakers sent me sail material to make the main and jib. They also sent me sail dimensions and the main sail pattern. Sam Lawrence of Bass River, Massachusetts, owns an older Wianno Senior. He has provided photos and building advice, plus and invitation to come down from Canada and go sailing on his boat to witness how these sailboats perform on the water. All the RC elements are now installed and working.
Time to show the progress of this building project. Thanks to the kind folks at Doyle Sailmakers Inc who sent me main sail data, I was able to make a 1”=1’ sail pattern. I showed in an earlier post the rudder servo instalment, now here is the main servo installation that will control the Jib and Main. (A work in progress) I have the lengths for the mast, boom, gaff but I am not sure if I will try turning them on the lathe or use a cut down mast from a Soling.

The Dumas kit (Carol Moran) mine is named Michael after my grandson. It sailed at a scale speed today. The Bunker and Ellis "Lobster Yacht" a Midwest kit, seen here towing a harbour tender. Harbour tender and Tugboat built by me. Dannieboy built the Lobster Yacht with added touches by Ron.

So, the hull has been fibreglassed, and several coats of primer applied. What next? Mark the water line as seen on the PDF and photographs? OR Place model in water, load up with approximately the weight of servos, batteries, and other building materials? Paint exterior hull or wait till interior servos are mounted? Scratch building questions...
All done and ready to sail. I took it to an outdoor swimming pool at a neighbours and did a Sytems check; Stability; All was fine and I suspect this is going Go like a greyhound on the lake! Put in a new sail winch robbe #8336; rudder servo is HiTec HS-322HD
The Winch paper work makes various suggestions, but I chose to run a single sheet line, aft through the single block. The main is the first ring, then the jib attached forward followed by a thin elastic which provides constant tension. Use a Bowsie if needed in your set-up to get the adjustment just right. My winch is currently being replaced as it was installed in the early 1990’s. Hope this is helpful.
