    Anchoring systems

    The only failures of rope rode I am aware of (please post examples!) were either chafe (bottom or roller area), or because less than 15 feet of rope were deployed (the balance was chain) in an open roadstead situation and the rope was forced to endure chain-like impacts without enough length to...

    Anchoring systems

    The 8:1 safety factor for nylon rope is common and well founded in experience. That is not a mistake. The problem is that the details of the testing basis for H40 has been lost to the sands of time when the developers passed. The understanding is that a series of experiments were conducted...

    I am the Boat Battery Executioner.

    That is a reason to limit installation but not to prevent installation. For example, I had 200W on the hard top of my PDQ catamaran, with room for more, but I have 50W on the companionway slider turtle of my F-24 (see post#4). Completely out of the way (non-trafic area) and enough to maintain...

    I am the Boat Battery Executioner.

    Why. Just curious, not critical.

    I am the Boat Battery Executioner.

    Unless I'm missing something, I think it is obvious to you and all, that your charging resources are inadequate (sounds like you keep the boat on a mooring?). LA batteries really like to be fully recharged after each discharge and not discharged below 40-50%. I think a small (50W should do)...

    Keep fuel tank full?

    This is probably the most common source of water in the fuel. I've seen some fills in some really stupid places.

    Keep fuel tank full?

    Perhaps that was a joke. No, in this math it does not, really. I have also inspected a few marine tanks, same problem. I've see condensation inside downward sloping fuel hoses. That fact that it is in the bilge of a boat does help. The fact that boats are within a foot of the water all the time...

    Double braid rope eye splice woes

    The core slipped out. You need to lock stitch the bury or whip the throat, same as splicing hollow core. I've see this before, on boats and on lines that were put in the washing machine.

    Keep fuel tank full?

    The problem with this link is that he does not actually understand the math or the phenomenon. Some is correct, a few things he misses. Example. One of the first things a large diesel tank inspector is trained to do, before entering a tank, is to check the roof for serious internal corrosion...

    Tricks to prevent topping lift snags

    Personally, I like having a topping lift available as a spare halyard. It has come in handy a number of times on several boats. Snags have been rare, but I think multihull roach helps. I just have to watch it on the hoist.

    Marking anchor rode

    Then you would never sail the mid-Atlantic, or rather, you would miss a lot. Remember, there's not much swing when you only have 50' of rode out. Different boats, different long splices, and even with my cruising cat, I would have felt those soundings looked just fine.

    Sail Track Lubricant

    Yup, like this: Either home made or purchased. You can make your own with some luff tape and some grommets. Shooting the hose at the track also helps. You can soak the cleaner with anything from soap and water to mineral spirits, depending on the problem. The makers of the cleaners I show in...

    A windlass near accident that happened to another sailor

    I would also hint that securing the rode to the windlass only (which sounds like the case) is also iffy. They've been known to run out also. The switches are known to fail, and they can fail "on." Not the first time I've heard this one, nor the second.

    Marking anchor rode

    Most of the time I sail with the electronics turned off. The cell phone stays in the pack. Just not interested in more digital data that I don't need. Sailing is about the senses.

    Marking anchor rode

    And from the times I have seen them used, measuring by hand is faster, easier, and accurate enough.

    Marking anchor rode

    I never marked the rode on my first (27') boat. I'd do the math in my head and then pull the rope out of the locker in fathoms (arm span). Marking the rope did not occur to me, since fathoms was so simple. Typically I needed 5-10 before attaching the bridle, so it took only seconds, and I...

    methyl hydrate

    Same heat. More soot BECAUSE of the isopropyl. That is what they add to make the flame more visible. Methanol. No soot. Oriogo does not recomend methanol, but I'm not clear on why (the company that owns the tech now does not have this prohibition). Ethanol. No soot unless the denaturants cause...

    Marking anchor rode

    I sort of agree, but just so you know... I anchored in 4' of water last night. That has never been unusual for me. Locally, tide is about 1'. Allowing for 5:1 scope and 3 feel of freeboard, that's 40 feet. I use a snubber (bridle) that extends about 15' forward, so if I attach at the 25'...

    Last straw

    I don't know the specifics, and don't really want to, but... It's just a forum. A watercooler conversation. I try to help and I'm sure I've said things I should not have. I am sorry for that. But we really should all just try to enjoy the conversation. If I have something I want to say, the way...
