I'm building a 39" model of this tug, there are no plans available, so I'm working from photo's taken on a visit.

I am stuck for one piece of info, how many blades are on the prop??

I have tried contacting the museum in Liverpool, but a more intractable bunch of people, I've never met.

They will not answer emails, in fact, email them & it tells you it's incorrect.

If they want support for this vessel, they better get their arse into gear, cos I won't support anyone who
displays this sort of "can't be bothered to answer a question", bugger the donations.

I agree totally kev,  they wont even let me take my little dog in which fits under me arm, and yet the café attached to it will allow you to sit with your dog under the table...…….had an argument with them about such intransigence only a month ago....their face to face contact with the general public is s*** as well.

but to answer your question I would stake my reputation on the prop, if it is an old diesel or steam tug, it will almost 100% definite be a 4 blade prop, and of a deep pitch to give greater towing purchase than for speed. if a modern tug with kortz nozzle, it could be 3 or 4 blade with softer pitch.

just seen the tug you are building, which is the tug in the docks as a visitor attraction, i'm almost certain its a 4 blade but am down on the albert docks tomorrow lunch time picking up a friend of my daughters, and having lunch at the Pump House, so will go ask the guys how many blades the prop has fir you.

BIG thank you if you could do that, this is my first 'ground up' build, I don't care how long it takes me, but I want it to be as accurate as my
minimal skills can make it (seen some builds on line & they look nothing like the real one).

Please feel free to send me a pm if you get the info.

Kev.

hi kev. got the answer today. 

I did so ask the engineer of the tug. the reply was that she was originally from new, fitted with a 3 blade 9' 0" diameter prop, but it was soon found that she was somewhat underpowered with that, 


and so it was changed to a 4 blade 10' 6" diameter across the boss propeller which made an enormous difference to the positive and efficiency if the tug..........so there it is.

the choice is yours.

I would have taken photos for you of the vessel, but had forgotten my camera, but if you do want some I. take some next time i'm down...………...down pretty regularly, at least once a month.
