Transducer in a standpipe.

    Bookmarked. Interesting strategy with compartments and pilothouse. It is interesting how different Gazelles are put together.

    The standpipe (to above WL I would guess) makes sense, "built to be sheared-off" less so. Does that mean the stand pipe can safely be sheared off? or the transducer can shear off the bottom?

    Len,

    Thanks for the question and for pointing out the ambiguity! I’ll fix that wording. The standpipe is almost definitely not going to be sheared off. There’s enough surface area that it should be capable of lifting the entire boat from that point (it is certainly not designed for lifting though). So the plastic transducer is capable of shearing…but we’d hate to have to replace it!

    Today’s project was routing the transducer cable to the chart plotter so we have electronic depth now. It might not sound like much, but it’s been a two-year project because we had to build literally everything but the hull itself to get to this point. It’s a milestone for us. The transducer is in an aluminum standpipe, is built to be sheared-off, and is designed to withstand freezing water inside. Prior to this, we used a leadline as our only depth instrument. We still like leadlines and plan to keep using them, but this add a little bit of safety.

    Hello all! My wife and I have been rebuilding a JR Colvin Gazelle schooner (for the last 3.5 years) and though we’d start sharing some of the projects. We started a website at the request of family and friends. The website is www.SailingGlacierGem.Com. Today’s project was routing the transducer cable to the chart plotter so we have electronic depth now. It might not sound like much, but it’s been a two-year project because we had to build literally everything but the hull itself to get to this point. It’s a milestone for us. The transducer is in an aluminum standpipe in case it is damaged, and the standpipe is designed to withstand freezing water inside. Prior to this, we used a leadline as our only depth instrument. We still like leadlines and plan to keep using them, but this add a little bit of safety.
