Tow length..
« on: August 05, 2014, 07:54:11 PM »

Quick question for all you tug towing experts...


My little Atlantic tug is now ready to go, I've swapped the radio for a Planet 5, and swapped the battery pack to a 7.2v 4200a/h pack. Apart from some added detailing, she's basically stock.


Question is...how long would the tow rope need to be to tow a loaded barge around twice the size of the tug?

Rich,
It depends where the barge is being towed.
In almost anything but a sea crossing the tug would be strapped alongside the barge.
It then depends on the availability of sea room to the length of the tow rope as when towed astern you have no "braking" on the barge.

Hi, Sea tow, long. Confined waters, short, IMHO. Nemesis

For a model - the length of a piece of string.

Now I need something to tow!

I'm not towing a thing that size! A barge type vesel, around 40"-48" ish will be ideal.


My poor little tug...towing that monster... <:(

I am trying to persuade my Dover club to build something like the Chantry Oiler,  did you have a hand in making it? and are there any plans, sketches of the hull etc,etc.

Thanks,

Len.

It would actually be pretty awesome. You'd get a glimpse at how real tugs operate. I've had the opportunity to play with xtian29's toy for tug, a 300kg/4m (13ft) tow. You can feel the inertia. And even my springer was probably too powerful. I should have restricted myself to only half throttle to make it really challenging.

A 48" tow is not going to give you much of a challenge. But of course there's the logistics. I'm actually building a 48" barge for my springer. But with a mere 20kg of ballast (4 lead ingots I'm going to get as far from the pivot point as possible) I suspect it won't be that much of a challenge. But at least it'll fit in my car without too much hassle.

Would it be possible to have a copy of your sketches? I will pay any costs incurred.

A little off topic.  If you are towing astern, on a very short line, how do you stop the tow?

Turn the tow quickly through 90, stops dead.
