The saga of the leaking Clive Puffer Several friends had mention to me that the prop needed to be above the water line so out came stuffing box mounted motor higher so prop shaft above water line & replace shaft & prop shaft . While doing all this It donned on me like a light going off that the rubber shaft was lower than the water line & I think water was entering up rudder shaft . Photo shows area where water was when it was in water & the tube for the rudder shaft was below that so added more stern depth .Made up another rudder shaft that is higher & tube is also now higher.
Chum444, is your "stuffing box" the size of the large diameter tube under the large filler and the rest of the shaft slips into the shaft tube? If so, the sealing area seems kind of small.
My preference is to have a fairly large sealing area. For example, using the attached drawing, the two ends where the shaft slip fits into are each about 5/8 inch long leaving a long void between the shaft OD and the tube's ID. [EDITED: this area is filled with the sealant lube.] Thus I have no problem with leakage when the entire shaft is below the waterline.
Also... as you can see in the photo, the prop shaft is horizontal and sits about 2 inches (50mm) below the waterline. No leaks if you make the stuffing box long enough and use the right sealant lube.

Was asked for more info . So here are a few photos . This mini humidifier uses water only to generate fake smoke no smelly baby oil & varsol odor 50%-50% mix for Graupner smokers .I get the power to run unit from the receiver battery port as the unit uses a USD port to make it work so I got a old servo & cut the wire off it removed the signal white wire & used the black & red wires to power up unit . I have to turn model on then power up the Humidifier to start fake smoke put the cabin on model & away we go. Make sure Positive & Negative are put in proper receiver slots Please don't damage receiver if it's plugged in wrong.
Having done a bit more trimming the lee helm is reduced but a bit like squeezing a balloon it has given me other issues. Anyhow, Andy a proper sailor took her for a spin and after sort of getting to grips with the controls he then went racing with the df65's. Camera battery died before the end of the race but got loads of good advice for the next outing.😎
Built from Hampton fishing boat plans in 2018
Converted to hybrid in 2021 - Sails replaced with dericks and 5 blade prop gets fitted.
Becomes a Lobster boat.
As far as I know, there is not a model boat club at Madrid. However, modellers gather Sundays at 10:30 to sail at a pond -actually a set of four connected ponds-, located in a municipal park, in the south of the city. Access is free.
The boat in the video is a sidewheeler, scratch built by my good friend Eduardo Yraola, who is a far more accomplished modeller than I am. She has steam propulsion, and sails at a majestuous pace.
Tomorrow the Confederation Marine modeler's will have our first meeting & the theme is bring one of your oldest model boats . So here is my Billing's Cutty Sark Built in 1977 for my sister she took it to her in-laws Manor in Milford Bay Ontario their it stayed above the fireplace for 20 years .Property was sold & it then went Amestburg Ontario for another 20 years Then it was returned to me.
Ian Potts built his model from the David Metcalf kit and sailed the model at Boundary Park on our Wednesday 30th August meeting. Unfortunately there was a problem with one of the props and rudder (all now fixed) so the sail was short. Sails realistically and is really well built and detailed.
I Must say i love RNLI Model boats
2 built watsonclass and Trent and the 3 one shouldbe on his way. The Tamar scale 1/12
That will be the next project After Finishing the Harro Koebke
Today, as the temperature rose to nearly 90F/31C the St.Pierre Dory was launched at Balsam Lake Provincial Park. Water was pleasantly calm. My grandson handled the controls while myself and Grandma took pictures to document the event.
Very pleased with how well it performed. It is very sea worthy even riding the swells left by passing full-size runabouts.
The only issue was the motor was extremely hot to the touch. This could be caused from the wrong prop.
Ronald, the prop is actually 1-3/4" ... in the photo you hav indexed the left blade to the end of your ruler, not the "0" point on the ruler. My 33" PT109 calls for a single 1" plastic prop to reach scale speed. I think you need a smaller diameter & much less pitch to alleviate your motor heating issue. Heatsinking, & watercooling or a fan will not fix your issue.
She certainly handles well in the water. That would be a nice one to enjoy cruising around with. From the video it looks like the velocity is more of a speed boat rather than a dory.
Nice job!

CreweMBC live Steam TID Tug by Brian Clewes sailing at Boundary Park
Managed to capture some video of Brian Clewes' live steam TID tug on the lake this Wednesday 19 October. First chance for a proper sail and a bit more ballast needed.
The Juliana II - a Hampden plank-on-frame Schooner
This was my very first RC project. In fact, it was only to be a static model, but then things changed.
Currently she's a shelf-queen as the rigging takes a while.
She can be converted to a fishing boat and fitted with a 5 blade 42mm prop and brushed 540 motor.
The sail rudder is larger and requires the prop to be removed.
Had a little trouble getting my sound to work properly but with a little fiddling got it working a lot better had to reverse motor leads & switch transmitter forward -reverse switch so it would work in forward direction .
On Halloween morning Sunday Oct. 31 2021 ran the Sequin with several other club members at Spencer's pool may be last run this year with weather getting cooler . The lake freighter was her first run & just needed a little ballast weight at the stern prop wasn't deep enough Boat belongs to a fellow club member .
