Tugboat towline

It's electric 2, 12 volt motors driving 4" dia. 4 blade bronze props. The tug is still listed on the Dumas boats website but I think it may be out of production now.

Sounds like a good way to spend a hot day.
I am not familiar with that particulat model ... it is steam or electric?

In most of these cases the actual wire would end in an eye splice around a thimble, which would be frapped with more wire.

Thanks that's what I thought, I have lots of tugs and they never say how to terminate the towline. I am building a Dumas Mr. Darby that I am going to pull myself around the lake in a raft. The Mr.D is massive 47" LOA and around 80 pounds sitting at the waterline.

Well, it turns out I'm starting a tugboat project and have been doing some research, so here goes ...

It depended on what the tow was.

Towlines were often wire cables with a rope section in the center to act as a spring. They were held together with swivels, clevises, bowlines, or a combination depending on the boat and the tow. Sometimes the spring was not used.

At the towed end the wire went over the casualties' bow or stern as appropriate with chain and/or bridles to prevent chafing the wire. If the wire went aboard the casualty then it was tied to the ship's bitts and a sharp eye and a lot of grease were applied where the wire left the ship. Often the casualties' anchor chain was fed out for this purpose, in which case the towing wire was shackled to the chain with a swivel.

In most of these cases the actual wire would end in an eye splice around a thimble, which would be frapped with more wire.

Hope this helps,
Bruce
