Yes, I admit it – I could not stop once I started researching the Bascule type of bridge. So, this is somewhat of a continuation of that post. Bridges are amazing – maybe this is a little boy thing. They are big, heavy, mechanical structures most often (these days) made out of steel. The engineering… [Read More]
Bascule Bridge
I was perusing a nautical chart the other day and noticed a bridge that did not have a raised vertical clearance listed. It was marked as a “Bascule Bridge.” The following chart snippet is what I was looking at – specifically the center bridge. For some reason, I had it in my head that a… [Read More]
Water Filtration
I made my own water filtration system that I use when filling my holding tanks. I take the approach that, no matter where it is from, the water is dangerous due to flukes, cysts, parasites, bacteria, and so forth. Many of the health problems in third-world countries are due to contaminated water. My “system” is pretty… [Read More]
Electrical System 101
There are a lot of electrical system questions on the various forums and messages boards. I certainly do not have any new information but I thought perhaps stating what I know might help some folks. I’ve certainly listened to two people say the same thing and only understood one them. Let’s limit our discussion to… [Read More]
LED Lights #4
I’ve been playing with inexpensive LED lights for the sailboat for a while now. Specifically, the Festoon style bulbs. For the history; view post #1, post #2, post #3, and post #4. I think I have made progress this time. The current batch of LED lights are 18 SMD LED’s and are very bright. I took this… [Read More]
EarthNC Android App
There is a slick app available at the Android Market titled EarthNC. It is described as “seamless charts, user waypoints, and realtime navigation. …features seamless NOAA marine charts for US waters, user waypoints, and realtime navigation.” I downloaded it and have been playing with it for a couple of weeks (on my Samsung Galaxy S… [Read More]
Power Inverter Planning
At first glance, selecting an inverter to convert 12 Volt electricity in your battery bank to 110-115 volt “house” electricity is easy, right? Well, as with most things, nothing is easy. There are a lot of options and a lot of things to consider in your decision making/product selection. I certainly do not have all… [Read More]
Shoal Fin Keel
There are a bunch of strange terms in the boating world. One used in regards to sailboats is a shoal fin keel. There are lots of different types of keels and I thought some photos of the last haul out of my sailboat might help in understand what a shoal fin keel is. This is… [Read More]
Port Light Seals
The port light seals (gasket) on my sailboat were becoming dried out and would stick when I opened the window. I do not have any leaks (that I know of) though. I had read that the best way to freshen/recondition these seals is to work some white Vaseline into them. This past week, I took… [Read More]
LED Cabin Light Testing
This is very un-scientific but is yet another data point for me. I installed the festoon LED cabin lights mentioned here and waiting til it was dark outside. The results were ok but not what I was hoping for. The cabin was not well lit. Rather, very dungeon like. From this test, it is clear… [Read More]
