Thank you for pointing me in a direction. Im really quite unfamiliar with most boat terms. Further to your help I did some research on "skeg" & found this which is also a keel extension but projecting downwards from the hull, faired a bit more than just a bearing at the base of the rudder
Due to the new gaffer where I used to work frowning on homers , I purchased the wood pack from Sarik which arrived this afternoon its really nice wood and well cut , it consists of the keel, frames and deck (photos to follow)this is a Chine hulled tug and was fortunate when clearing out my late mothers house up the loft (attic) were a few old plywood tea chests in the need of some t.l.c .
Cheers Marky👍

sorry its been a while, I didn't realise just how long it had been until I saw the last blog post ,due to circumstances I at this moment have a very low immune system so cant leave the house , so nows the chance to get on with the build .
I now have the decision to make whether to bite the bullet and build her as a rc ship or plump for the old worn road of static .
If I decide the rc route iI may be on quite a lot with questions .
Question 1- how do you determine the length/diameter of the prop shaft .
Question 2-the build guide says the motor. is a Como 500 with a 6:1 reduction gear ,is this the only motor I can use or are there any alternatives ?
That's all for now
all the best .
cheers Marky

If your looking for a good motor then I would say look at the Torpedo 500 6.1 geared motor . best place to fit motor depends on what your building, tugs etc need there propshaft as straight as possible along the hull whereas fast types need propshaft at around a 10 degree angle
My brother has just given me a couple of motors (working condition) that he got out of old battery powered drills , he said one of these motors should suffice ? we hooked them up to a 6volt m/c battery and they both ran at a steady rate
any thoughts 👍

using a motor of unknown specification may have its problems so I would be wary of it. By all means give it a try (I would) but also, be prepared for the unexpected. Don't be disappointed if it doesn't work out 😉
In North America circa 2002 use of cordless drill power train was common in larger RC aircraft as the belt reduction cud swing a large prop. The nicad drill's battery gave a 3 to 5min flight with those brushed mtrs
I've decided to make a start so tonight I'm going to start taking the keel and frames out , I got the wood pack and its good quality ply only strange thing is some frames are 6mm and other frames are 3mm and have to be doubled up ,its the same for the keel 2x forward ends and 2x aft ends obviously there's method in this madness. will post some photos later or tomorrow

Cut the pieces out ,well nicked the wee tabs and popped them out ,the frames cut in the 6mm ply were a bit scorched so Black fingerprints everywhere 😀one of the 3mm ply sheets is numbered so its just a case of pairing them up.
Will give them a light sand some time tomorrow and then make a pattern from the cut parts and that will give me a template if I want to make another tug .

Frames and keel doubled up and glued so leaving them clamped up overnight to fully cure .
Question - if you look at the picture of the keel you will notice I've marked the position of the prop shaft on and it's quite near the top edge of the keel ,can I cut a section out the keel to accommodate the motor probably between frames 7and 6 .

I popped into a wee model shop today (before hospital) alas no one knew anything about RC for boats the dealt primarily with RC Cars but the nice young man said they had a motor -esc combo that should work ,the motor was a 550 brushed motor with a 320A water proof ESC .
My question is would this motor combo do me for the tug?I
And it's pretty reasonable at £18.

Good evening Marky, I have a a large tug running on a 540 motor using a 12v 7ah sla battery with no issues, gives about 90 minutes running on full power while towing or up to 2.5 hours running solo.
As the 550 is much more efficient motor it should be fine.( it's the larger tug)
Cheers Colin.
Thanks Colin, I'll get the good lady to pop into the shop tomorrow and purchase the motor, that's me isolating again for 30 days after today's treatment .

That's me got my motor I now need the help of you kind ladies and gentlemen as to determine the length of the prop shaft I've taken a few photos for you to peruse ,on the drawing the centre line of the shaft is 6mm above the top of the keel, I'm proposing to cut a piece 1/2 the diameter of the motor out the keel to keep the shaft and motor as straight as possible strengthening either side , I'm just not sure whether to do this at frame 7 or 6 , in the photos There is a ruler on the drawing ,any idea what length the prop shaft should be?
There is also a picture of the drawing of the prop with a ruler next to it, what diameter should the prop be? If you take the measurement from the centre line to the top it's 30mm ,is this a 60mm prop? Last question as its a single prop should it be left or right handed ?.
Thanks in advance Marky

Very useful on boats that sit on the bottom at low tide in shallow harbours.
Cheers Colin.
