The bow thruster
The bow thruster was weaker during the season.
Eventually so weak that the bow barely moved when the propeller was activated.
I figured it was overgrown with broods and hoped to be able to clean it from the dinghy I found from the shed.
I carried it into the car, drove down to the harbor, carried it out onto the bridge, where I pumped it up. When it was full of air, I threw it into the water, pulled it aft and got into it from the bathing platform.
Standing, I pulled it to the liner, where I found the tunnel to the bow thruster.
The tunnel was close to the waterline, but even if I stuck my arm all the way into the cold water, I couldn't get a good grip on the propeller.
From what little I could feel, it didn't seem like it was very strongly greeted. I pulled the dinghy back aft, got into the boat, went down into the forward cabin, removed all gear, duvets, pillows and mattresses so I could examine the engine.
There was 12,5V voltage on the motor. I started it by shorting the relay. The engine hummed fine, but I could hear that the propeller was hardly turning.
Out in the dinghy again, pull me to the lining and feel more thoroughly after.
Now I thought I could feel the fuss of roughers.
Probably enough that the propeller was almost stuck when the engine tried to turn it. Concluded that I would have to wait to clean the propeller until Heron came ashore.
Pulled the dinghy onto the bridge, deflated it, packed it up and carried it back to the car.
At the end of spring, we got Heron ashore. And yes, the bow thruster was completely greeted with rowers. I cleaned it. When Heron came back into the water it had regained its strength.
