    Names for Thing Anchoring

    There were several long threads on a UK forum the other day about a few things we couldn't decide what were called. The weight you place on a rode to hold it down. Chum is an old trade name. Angel, kellet (my favorite, because it can't refer to anything else), and Rider (also trade name) are...

    Ship-to-Shore Transport for <25-Foot Boats?

    Putting anything on the fore deck seems impractical. I'm not a fan of towing, because it slows you down and eventually the weather will require you to bring it in, probably at an inconvenient time. You can blow something up, to they are still big below decks and I'm not sure it's worth the...

    A Locking Safety Tether Hook That Can Rotate Off a U-Bolt?

    This only took about 25 pounds (measured) of pressure and came as quite a surprise. In this video, we see what could happen if the clip came across an obstruction, like a cleat: The full story is here: http://sail-delmarva.blogspot.com/2018/02/a-locking-carabiner-that-isnt.html and here...

    Singlehanded MOB Procedure--Outside Box Idea

    Ideally, you stay on the boat. Agreed, let's not flog that topic. I've written much about tethers, jacklines, and hardpoints. The problem with a trailing line is that the sailor cannot hold it. So let's just stop the boat. If we put the helm over the boat may tack off in a different direction...

    Water filtration/purification for non-pressure systems

    For those with pressurized systems, there are a wide variety of home and RV systems that can remove chlorine and cysts, and even bacteria. However, they generally used carbon block filters and require significant pressure drop to work. What do people with hand or foot pumps do, other than a...

    Wag bag vs. portable toilet for daysailing emergencies

    Most daysailors carry a portable, hoping not to use it, but it's good to have. Because it may not be used again for a month or more, it gets dumped and cleaned every time. In the winter, water must be exchanged for glycol. On the other hand, what if you simply line the bowl with a wag bag? They...

    Do magazines (and forums) focus too much on larger boats...

    ... at the expense of smaller boats and beginning sailors? I can see why Sail would do this; the advertisers need you to buy up. But what about the rest? Part of the dynamic is that writers have often moved up to bigger boats. We're old guys now. People that have sailed far tend to have larger...

    The Other Chesapeake--New Blog/Guide

    A Guide to Off-the Beaten Track--The Other Chesapeake This started as a book idea--primarily to make the work feel more worthwhile, I think--but by and by and with changes in policies at Amazon and other on-line sellers, I decided to simply give it away instead. If you have an interest in...

    What causes joker valve failure?

    I've been testing a bunch of chemicals on a fleet of donated joker valves from Groco, Jabsco, and Raritan. We're measuring changes in stiffness, resilience and size. We have a test rig (flanges and a standpipe) where we can test for leakage (back flow). We have installed all 3 types in test...

    Winterizing heads with ethylene glycol

    Pre-2000 the bellow was the Jabsco recomendation. Any reason why this is not still so? (from a 2000 forum post) "The manufacturer is, I believe, ITT Jabsco. Another name on the first page of the manual is PAR. The direct quote comes under the Maintenance/Service Instructions and is as follows...

    Are Joker Valves Interchangable?

    First, it sure seems that the joker valves one the Jabso twist-n-lock, Raritan PHII and Groco manual head are functionally interchangeable. Yes, there are minor differences in the molding and the flange on the Groco is about 1/16-inch thicker, but I betting all will fit and all will work...

    Using the head treatment as a bowl cleaner

    Note: if you're using one of those stinky blue treatments that contain formaldehyde or other disinfectants, this post isn't about you. But you would be better served by different treatment, practically anything. Raritan Engineering markets CP as a no-scrub bowl cleaner that is compatible with...

    Mast Hieght, Starwind 223

    Mounting solar panels on adustible feet

    Although using studs to make an adjustable mount is hardly a new idea (engines, street lights), I admit using threads in prelaminated FRP is an idea I stole from your seacock mounting procedure. It worked out very well in this application too...

    Sealing wire with butyl and heat shrink

    I read of this on another forum. I've sealed underground cable junctions up too 100 amps / 480V with butyl kits before; there are huge bulk things and I never associated them with marine application. Ordinarily, we seal wire junctions in damp locations using either a junction box or adhesive...
