Mailport & PS Advisor

Got a really fast boat? Zipping along at over 10 knots there are any number of ways air can suck down the leeward side of the blade, spoiling the coanda effect. When planing there are often some air bubbles under boat. If the boat assumes a bow-down attitude under the pressure of the spinnaker or as waves pass, the transom can come a few inches out of the water. Above 15 knots theres enough suction…

Regarding your report on props, (Folding and Feathering Props,February 2018), I installed a Gori propeller on my Beneteau 393 before setting sail from the Great Lakes to the Caribbean for a year.

Most times when I need a third hand, I can secure whatever I'm working on by jamming it in the groove between dock boards, or against a piling and placing a knee on it, or some combination. Work surfaces can incorporate cleats or holes for this purpose, but sometimes more specific clamping measures are required.

Like Tom Taylor and Joseph DiMatteo (see Mailport PS August 2019), Ive stopped using inflatable PFDs and instead wear inherently buoyant foam versions. I found that ones designed for dinghy sailing are often very comfortable and have convenient pockets for knives, whistles, flashlights, and even handheld VHFs (I keep one with GPS and DSC on myself, especially when single-handing).

If you can't position the jib clew exactly where you want it on all courses and in all weather, a barber hauler should be in your future, for even the most laid-back sailor. Here are some options.

With regards to your recent marine oil filter tests (see PS July 2019, Marine Oil Filter Comparison Test), having spent my career in the aeronautical engine technical field specializing in maintenance I must state my allegiance to non-encapsulated filters and independent housings. This trend towards spin-on filter assemblies prevents in my opinion the most important aspect of filter maintenance which is particle inspection. Filters are not removed so you can inspect or replace them, they are removed so you can ascertain your engines condition. This practice seems to have been set aside to make way to quick and easy maintenance using spin-on filters. Oil analysis is fine but it should start with a simple sediment inspection after a low cost electro- sonic cleaning in a 60 Hz bath (jewelry cleaner bath).

Mast steps are a great help when going aloft, but they add weight where it hurts most (aloft), and halyards love to get stuck behind them. One alternative is the Mast Mate webbing ladder, which hoists on your mainsail track.

I really appreciated the article Anchoring in Crowded Harbors (see Practical Sailor, June 2019). The difficult and critical part is always estimating distances, and the guides you gave (two-to-three mast heights, using fractions of a nautical mile, etc.) can be difficult to do accurately in a crowded harbor with the sun setting, with some of that information available only at the helm, and multiple boats moving to anchor. As a bow hunter, I am…

Simple tank fill advice from an old fuel oil delivery guy - when filling your boat diesel tank listen to the sound coming from the tank vent, it is attached directly to your tank. The fueling sound will change when the tank fills and fuel enters the vent line. Stop then. Dont leave fuel sitting in your fill hose in the off-season.

As an avid climber I pay attention to my aches and pains. To blindly ignore them puts myself and others at risk. The same is true for sailing.
