Riding the ebb, water pump woes and how thick is a Nordhavn hull?

Riding the ebb tide up Johnstone Strait the other day we saw a boat speed of up to 15.1 knots… and our normal cruise speed is 8.6 knots. That’s a hell of a push. I was too slow to get evidence of that, but this is pretty close.

The boats shown on AIS at the top right of the chart were getting ready to start the Van Isle 360 Regatta.

After arriving at Port Harvey, Gwen said that our domestic water pump wasn’t working…. AGAIN. It never completely shuts off, ticking over very slowly after all faucets are shut… as if there was a leak somewhere… but there isn’t. We turned the pump off, deciding we would deal with it in the morning.

Yesterday morning I woke up bright and early… to an impressive bout of gastroenteritis. It was not fun, and knocked me out for 24 hours. Glad that is over with.

  • This morning I went back at the water pump. I decided to install a small accumulator tank, hoping that might help. This is when I came to consider the question of how thick is a Nordhavn Hull? The answer(s)?
    1. That depends on where you measure.
      Not as thick as I thought.

    I was drilling a hole to mount the accumulator pump – and was planning to use a 3/4″ screw. In went the drill and out came a stream of water. Yes. Salt water. A short screw coated with 3M 5200 sealant went in pretty quickly and a bunch more was slathered on over it. Disaster averted. So the real answer is, at least where the water pump is mounted, no more than an inch thick.

    After all of that excitement, we still didn’t resolve the water pump issue. Accumulator tank did not fix the problem. I replaced the pump with a spare. Nope. Now we are back to wondering if there is a very small leak in some out of the way spot. We decided to leave it for now and simply turn the breaker on when we need water and off when we’re done.

    Today we are resuming our journey north,heading for Sullivan Bay in the Broughton Archipelago. Gwen did quite a nice job of getting Miss Miranda off the dock and underway.
