: An Assurance class conversion to Diesel power.
: model tugman December 08, 2017, 01:34:39
I have managed to purchase a new kit for the Assurance class tug, but as I already have one built as per the kit I looked around and found something a bit different, she was built as HMRT. Tenacity, then renamed Adherent, after being sold out of Admiralty service she ended up in Sweden where she was converted to Diesel power with 2x Fairbanks Morse Ex Submarine engines geared to to one shaft.
She also had alterations to her superstructure ,funnel and after deck but still her earlier looks were there.
So the first job was to cut out the anchor ports because as built they had external anchors, then I fitted the stern frame and rudder.

Should have put these on first, pictures as Adherent, Hermes and Canadian Viking.

Looks like an interesting build - like the lines of the Canadian Viking there.

What kit did you acquire?

Thanks for posting,
Mike

Model slipways Assurance class tug kit from E bay, it was completely untouched so a bargain for £200.
I think only the two were actually converted in later life and both went to BC ,strange really.

Next job tackled were the deck beams and installing the prop shaft, I have increased the number of deck supports and used laminated wooden ones ,but have faced the top surfaces with plastic strips as I am going to use the kit supplied decks and wanted a bit more support under them.
As I am building her as she was when diesel powered the tow hook table and engine room top have to. Be modified and moved further forward.

The Slipway is now back in buisiness after the Xmas break, and I have done a little more to Hermes.

I have realised that the engine room top is wrong so this is the re made article.

That's a good start to the year George. Looking good.
Where did you find that tow hook?

Hi Steve, itís the one that came with the Assurance class tug kit from Model Slipways.

The end is in sight now just a few more bits to add , and paintwork to touch up.

A couple of comparison pictures, of the Assurance class as built and the conversion to Diesel power.

All done now , test tank trials done ready for sea trials now.

What a cracker! That turned out excellently, as usual, George. Your work is always very impressive Ė and inspiring, and your regular input is keeping the forum alive.
Must just about be a record build too, considering you stopped for a refreshment break. Would be a shame to have a breather between projects when you're in such good form Ė he he.

Great subject too. So different from an Assurance, a real transition from '40s to early '60s design. How do you go about picking a project?

Steve

Looks great George!  Did those pix I sent do you any good?    Get it in the water and on a nice windy day!!  Look forward to pix!

George I just noticed you named your other one RESTIVE, which is the real tug used in the movie, THE KEY, which my W39 is based upon!

Hi Steve, as for picking a subject, I am now at the stage of looking for tugs from the 1900 to 1975 era that catch my eye, modern tugs do nothing for me I am afraid,  my brother John is the modern tug builder ( tugnut) on the forum.

Ant yes thanks Tug the pictures were very handy being an ex civilian tuggie I canít bring myself to paint a lovely tug grey,so chose the yard craft (RFA) colours instead,  Although a good few years ago I did build an Assurance class at 1/32nd scale completely plank on frame, as Assiduose because when she was managed by Watkins during the war my Dad was Chief Engineer on her.
The model was fitted with a cheddar proteus steam plant as well.

Her sea trials went well this morning, no really rough water I am Afraid.

Looks great!  Another beautiful job. I forget what motor you used in this one.  Was it the kit supplied motor or did you go another route with it?  Seems to scoot right along, looks faster than mine with its supplied motor.

Hi tug, she has got an MFA 800 motor theybare not very expensive about £29 and it is driving the kit Prop, I didnít know that the kit came with a motor , the two that I have had didnít.
I think though that I will take some pitch off of the prop asshe is a bit fierce.
: Re: An Assurance class conversion to Diesel power.
: tug-arlyn-nelson January 27, 2018, 11:15:28
Mine came with a MFA 500 which might explain the "fierceness" of your system, lol. Not sure it was actually part of the kit, but was the recommended motor.

And another superb tug slides down the slipway built by George. It's good to see how they were converted after naval service to carry on working for many years in private companies. That knowledge is being passed on everytime one of these is built. The quality of building gives us all somthing to aim for, Wonderful job George.  Brian

Yes thatís right, but we have a 16ft Tanker in the club to tow around so having a bit of power helps, plus after conversion they had 4,200 hp ,2x 9 cyl cooper Bessemer. Engines, and compared to the 1300 they were built with ,quite a step up.
Well thatís my excuse anyway He He 😂😂😂😂😂😂
All the best mate. George.
