Plugged Through Hull Solution

After a grounding blocked a through-hull with seaweed, the author was asked to find a solution for a difficult-to-clear 90 degree elbow leading to the raw water strainer. Turns out replacing the hard elbow with a longer length of hardwall hose was just the ticket.

The captain made a navigational miscalculation so this 2005 Sabre 386 rested on a shelf just outside Cameleon Harbour in British Columbia for the tide to return. As a result of this temporary grounding, seagrass entered and blocked a through-hull. Identifying details have been omitted at the request of the captain. (Photo/ Bert Vermeer)

My summer cruise took me up to the Discovery Islands just north of Desolation Sound off the coast of British Columbia with sailing buddy Paul aboard Natasha, my 1978 Islander Bahama 30. We met up with Chris sailing solo aboard his 2005 Sabre 386 in Cameleon Harbour, a remote, forested anchorage far from the busy life ashore. A pleasant evening was shared over dinner and drinks as the sun set over nearby mountain tops.

  1. The usual problem is getting the hose to release from its fitting. Heat applied gently has worked for me. Thankfully, I have only had to work at the dock where electricity to power a heat gun was available.

    Reassembly using silicon (brake) grease will ease the process the next time. Petroleum grease will damage hose. Syl-Glide is my go to. Also works as a lubricant and rejuvenator for any rubber gasket (hatches, fridge, etc.)

    Using the dinghy pump to apply reverse pressure to clear the debris is very clever. So is the using a length of hose to eliminate the elbow. Thanks!

  2. I had a similar problem in my A/C cooling circuit. I replaced the sharp 90 degree elbow with a Groco FFC Series Full-Flow Pipe To Hose Adapter – 90 deg. which is a sweeping elbow. End of problem.
