  • Seven years in the water

    I looked at a 26' Shamrock that was well maintained until circumstances caused the boat to sit in a boat house in salt water since 2012. The bottom was painted with a barrier coat. There are oysters growing on the trim tabs and the bottom is completely covered with barnicle's. The bilge was so dry it had dust in it.
    What would be the best and worse scenario to fix this?
    Thanks.

    Wow...dry bilge? I would imagine have it hauled and soda blasted. The blasting should show blisters etc that may be on the bottom. Then a matter of fixing the blisters and applying a barrier coat. That would be my thinking. I might be doing a little dance with a dry bilge.

      X2 on the soda blasting, and pay someone else to deal with the mess. Sometimes the disposal of the waste can be a PITA and hardly worth investing in the tools and tarps needed to do the job for something done infrequently. Best thing we did for ours. It will give you a fresh start. For inspection purposes you may be able to pressure wash off some of it.

        Start scraping and see how easily they come off. I deal with this all the time. Hauled the boats for the storm and every bottom was clean except for one side of the 14, which was/is covered with oysters. Maybe I ran out of paint before I got to that side. A long handled ice scraper is handy. Oysters are tough, barnacles, not so bad. Powerful pressure washer may be all you need for the barnacles.

          Thanks for the replies.
          I'm looking at purchasing this boat and would like to get some sort of an idea on the possible condition of the hull once it's scraped and soda blasted.
          Is it possible that it is not repairable?

            I would highly doubt that it would be beyond repair. Given that bilge is dry it would seem that hull is not compromised. I would suspect that it would need some glasswork and barrier coat (which i am doing to mine next spring)

          I would guess, just a cleaning. Bottom paint and, if blasted, barrier coat.You would be surprised what a powerful pressure washer can do.

            Fiberglass is very porous and can soak up water. A lot of hull blistering comes from the bilge end of the hull from water sitting in what can be an untreated area. While blisters can obviously come from the displacement side, I think a dry bilge is a good sign.

              So inquiring minds want to know. What gives? Are you getting a new project? Pictures would be nice for us poor folks not shopping right now.

                Make sure to power wash as soon as it's pulled. Once the bottom dries, it is much harder to get the crud off.

                  Seven years in salt water.... My first concern would be the running gear. The zincs should be long gone, then it likely started eating at the shaft, rudder , trim tabs, and prop. Examine closely for pitting. That said, if the price is right that is easy to replace. Also, the electrolysis MAY have effected the engine if the raw water was solid in the hoses (doubt it bu possible). Not sure how much engine electrolysis would go through the shaft. If the price is right, and otherwise she appears in decent condition, I wouldn't be afraid to gamble and be prepared to change all running gear and engine. I'd haul her and try to get her running then assess what worked before wholesale component replacement.

                  Kept my boat in the water 5 years between haul outs the last time and no blisters. (Changed zincs in the water.) With the exception of haul-outs, my boat has been in the water since 1991 when purchased. I did have a few blisters in 2003 which were addressed.

                    Cecil, good point on the corrosion. How much electricity in the area? My 26 has been in the water for 13 years except for the frequent engine change. I have a couple of blisters which I choose to ignore.
