Tiny Tug

The Little Tug

The first iteration of this design looked like this,

It was obvious to me that there was too little bearing aft to make this a successful little tug. Working from the original concept I redrew the lines to give the boat more bearing aft, to place the center of the deeper box keel under the steering position and give a little more room for the propulsion system.

The original lines lines looked like this,

The redrawn lines like this,

As you can see the stern is wider as is the box keel, there is more bulk in the box keel closer to the fore and aft centre of the boat giving more space for the propulsion system.

We discussed the propulsion system here  and here . The little tug with the propulsion system fitted looks like this,

The two wheels at the helm station control the direction of travel, the smaller wheel controls the forward and aft motion of the Kitchen rudder clamshells given reverse, neutral and forward and the larger wheel moves the rudder arm from port to starboard. Here is the rudder layout.

You can see from this drawing that the bulk of the box keel falls right under the helmsman, the towing point and the motor.

Here's the tug in profile and plan. I'm pretty happy with it.
