On Derwent6 we always keep the bilge clean. This is the bit at the back of the boat which collects the water from the stern gland where the propeller shaft goes through the hull. The block is where Del's tool box sits..
We did some other jobs as well. We had a window which was leaking water when it rained and Del run some sealer round the joints where he found a hair line crack.. He had some special Capt. Tolley's sealer for this.
So keeping warm was the order of the day as we can hear the ice cracking as we move around the boat.
