My son, Lasse, breaking down the washroom in the boat. It´s hard work to get to the old through-hulls, under the sink.
While Lasse was working - I had the time to take a photo of the TRU - design through-hulls.
We are changing all through-hulls in the boat - over time- with these. This year (2021) we changed two - both leading water from the sinks. As you can see, we went for the secure version - mounting load bearing collars, to prevent damage to the through-hulls themselves. It´s arond 125 Euro in total for one "set".
