Some Propane Dos and Don’ts

Theres nothing more satisfying than capping a pleasant day on the water with a good meal, be it burgers and dogs on the grill or some fancy, culinary extravaganza whipped up by the galley wizard. Most marine stoves and grills use liquefied petroleum gas (LPG). Its efficient, relatively cheap, and widely available. Its also highly explosive-particularly with regards to boat installations-which makes proper installation and regular inspection so critical in onboard systems.

Holding Tank Vent Fittings

As I plumb the archives for holding tank replacement info, I find excellent related articles (PS, February 2012, March 2012, and April 2012); all remind me to build in good ventilation. However, I am unable to find guidance on the merits of ventilation fittings. These stand at the interface of tank gasses and other contents trying to get out, and the marine environment trying to get in. Issues such as shape, location, mounting, and materials concern me. Can you bring some fresh air to vent fitting merits?

Testers Check Growth in the Lab and on the Boat

When testing a chemicals toxicity and its ability to biodegrade, a common procedure is to dilute each target chemical at various ratios of interest, and then to inoculate each with an acclimated microbiological seed. For our test, the seed was developed by filling a five-gallon bucket with several gallons of water and a weak mixture (two percent total glycol content) of all of the winterizing agents to be tested.

Heart Replacement

Sixteen years ago, contributing writers Joe and Lee Minick equipped their Mason 43, Southern Cross, with a Heart Interface Freedom 20 charger/inverter and a Link 2000R from Cruising Equipment, both made by companies based in Valley Forge, Penn. When both of these units were ruined during a knockdown (see PS, April 2013 online), they were forced to look for a replacement.

Marine Wiring: Are the Pricey Options Worth the Cost?

This article launches Practical Sailors long-term test of electrical wires, electrical connections, and corrosion inhibitors for electrical applications onboard sailboats. Ultimately, the goal of this ongoing project is to examine corrosion in wires and connectors in a marine environment. More concisely, it could be presented as a closer look at three common elements in marine wiring to answer some basic questions: What is the best wire to use on a sailboat? Is it tinned wire, automotive wire, or stranded machine tool wire? What are the best corrosion preventatives? Do you apply the anti-corrosion treatment to every connection and every crimp, or just certain types of connections? What are the longest-lasting connections? Which were most prone to electrolysis? We made observations during the six-month test period without disturbing the samples. At the end of the full one-year test period, we will unbolt all of the fittings from the terminal strips and look for corrosion under the fittings.

Which is the Best Marine Inverter-charger for Your Boat?

To decide which marine inverter-charger best meets your onboard power demands, first consider how it will used, how and where it will be mounted and what is required to fit with your electrical system. After testing multiple marine inverter-chargers, Practical Sailor offers this report on the units’ inverter capabilities and a follow-up review will report on the units’ charger functions. There are two classes of marine DC inverters: true sine wave (TSW) and modified sine wave (MSW). Each uses a different method to produce AC voltage. Practical Sailor evaluated modified sine wave units from Charles Industries, Magnum Energy, ProMariner, and Tripp Lite, and true sine wave units from Magnum, Mastervolt, ProMariner, and Xantrex.

When Choosing Pilots, Err on Side of Caution

In a nutshell, autopilots have one main function: to assume control of a vessels steering and control its heading, be it a specific course or on a selected route or to a waypoint. As with any crucial piece of gear (anchors being a great example), cost should not be the primary consideration in the selection process. Its crucial to select a unit that has both the power and ability to steer your boat effectively in all sea conditions youre likely to encounter.

Overheating in Docklines and Rodes

With hurricane season hitting full stride, many of us are going over our rope inventory, making sure we have more than enough lines to secure the boat. Chafe gear fights external friction on our lines, but how do we combat internal heat build-up? Dock lines are particularly susceptible to overheating. If the boat is exposed to short-period chop from the side, the frequency can be high and the force can exceed the 10:1 safe working limit, and even with rain or spray to cool the rope there may be significant weakening due to internal friction.
