Thanks fellas.   :}

You can probably guess that I didn't pick the colour.  Must admit, I rather like it now.  No sailing today as grandchildren call.   %)   I'll try some waterborne photos soon.

Cheers

I've just returned from the lake.

Wow, it was lovely now the children are back in school and the sun was out.   Glorious afternoon.  I had to put a few stones into the hull to balance her out and she went like a train.  The 900 motor was certainly overkill..  I will be changing it for something more sedate as i have plenty of spares still left in the boxes.

Here's a few pictures on the water.  I will be the rest of night making the YouTube film.

Cheers

Thanks Guys,  it certainly was a pleasant afternoon. 

I met a lone yachtsman with his sail boat on the water.  Due to the lack of wind , that was the end of his sail,  so I invited him to take my radio and have a try.  I think we have a convert.  He then held the camera whilst I motored about like a young-un trying to make a movie.   %)

Made me want to make something else now.   :-))

Cheers

I originally walked up the lake with the dog and you're right.  He was the 'Only' yachtsman there.  I wish I'd got his name now. It was so quiet and serene but I was able to shatter that when I returned by car with my noisy tug.   :}

I did a scan of the lake with the movie and it really is a nice place.  I'm still working on the YouTube film but it will be out soon.

Ken you say the 900 is overkill I say NOT ...why ....well you dont buy a ferrari and drive it flat out do you.

Have you forgotten that the throttle is variable and  not an off/on switch  {-) {-) {-)

Seriously the power you have would be ideal for tug towing  O0 O0 O0

Hi Dave,

Whilst I agree with you in theory, in actual practice it was moderately difficult to go  'very slowly'.  She is fitted with a 4 blade 60mm prop and a cr**p  Chinese speed controller, so when underway she was pulling from the off.  I managed to create a  'bow wave'  the like of which has not been seen on our lake, ever .  When I've put up the film you will see what I mean.

I recon if I had a rope to the shore and connected it to the car, I could have moved it.   :} :}

Another feature which became noticeable was then when throttling down from speed, the boat tended to pull severely to the right.  I figured this might be due to the 4 blades stopped in the water and causing a turn effect with the curvature of the blades ??

The  obvious solution is to gear down the motor.  The thrust would be still be considerable but slower.  The stability is very tender and she can rock from side to side.  The captain could go water skiing.   {-)

1st Point....get that motor aligned up properly you can hear it rattling on the video
2nd Point you NEED a lot more BALLAST as it seems there is a lot of weight topsides
3rd Point ....go and try it AGAIN......motor is spot on for that tug

Cheers Dave,

I've been talking to Stan and we conclude the Chinese speed controller is actually rubbish.  I did a bench test and gradual acceleration is not in their vocabulary.   %)    There is  NO  pull away acceleration.  It starts at half revolutions  (on the bench)  and it's stop or run half speed.   aeghhhhhhhhhhhh!

The motor is screwed to a plywood board which is acting like a drum. I will be keeping it after some mods to the balance are done.
