Interceptors can sharpen up a boat’s performance and efficiency.
For decades trim tabs have been the popular way to adjust a boat’s running angle. They work well on boats up to about 45 feet but on larger boats, you need some seriously big plates, which can create drag and don’t always deploy quickly. That’s why lately many manufacturers are turning to interceptors, such as those manufactured by Humphree and Naiad Dynamics. These blades mount to the transom and drop down vertically into the flow of water coming from beneath the hull to create lift without producing the drag of conventional tabs.
Should we do end-of-season oil changes or can we stretch the old oil into the next season?
Carry frequently used maintenance part numbers, to-do lists, and shopping lists with you on your smartphone. Use any number of available free apps (try TurboList for the Droid and Easy Note for the iPhone) that will allow you to keep everything in either simple or categorized form. Or go a step further and use your smartphone calendar
Finally retired, you’re on a weeklong cruise aboard your trawler, just you and your wife. Suddenly your only engine quits, and you can’t restart it. Your peaceful cruise is over, and your wife is asking, “Are we stuck in the middle of nowhere?”
Question: I have a 39-foot Bertram with twin Volvo Penta TAMD74P-A diesel inboards. The starboard engine, if left idling for a couple of minutes—say, while I’m fishing over a wreck—will not rev up afterwards. Instead, it takes 30 to 40 seconds to respond. The fuel filters are new, and the fuel onboard is clean. Do you have any
If you’re on an extended cruise, you can never have enough of two things: privacy and hot water. Both problems can be solved, but the solutions are different in scope. You can take care of the former by purchasing a bigger boat. The hot-water issue is easier and less costly to...
When you’re winterizing your freshwater system and want to prevent messy spurts and sprays that occur when you’ve finished running antifreeze through the lines to the sinks, and the tank and pump are almost dry, cut the bottom out of a few
I plan on being away from my boat for two to three months and during that time, I plan on having someone periodically run my diesels dockside...
Question: I have a 1989 38-foot Bayliner with twin 175-hp Hino diesels that have been retrofitted with turbochargers, thus raising each engine to 210 horsepower. As I go from cruise to wide-open throttle (approximately 23 mph at 2800 rpm), turbo exhaust temperatures increase from 700F to 950F on the port engine and 850F on the starboard. When
Last month we showed you how to determine your boat’s cooling needs as a first step in an air-conditioning installation or refit (see article here).Now that you know how much space you’re going to be cooling and the size of the unit you’ll need to cool it, it’s time to select the
The owner of Honey Fitz made the right call—twice. First, after the former presidential yacht had paid many visits to various repair yards since the mid-1970s, he decided to undertake a full refit. Second, he hired Jim Moores of Moores Marine to do the job.
A real-world test of this bottom paint produces some definitive results.
Toward the middle of this past July, I had my Grand Banks 32 Sedan Betty Jane hauled at a local boatyard for two completely different reasons. First, I wanted to facilitate a first-rate wax job. Using a big electric buffer on a comparatively small, faux-planked hull
An extensive refit, complete with two Seakeeper gyros, put
These days it seems like nearly everyone is talking about going green. Some people are going all out, living in solar-powered homes and driving hybrid cars, while others require a bit more convincing before they hop aboard the tree-hugger
Question: The boys at the Ko Olina harbor are having a heated discussion concerning motor oil. Since Costco hit town, we’ve all been able to buy Chevron 15W-40 Delo 400 heavy-duty motor oil at ridiculously low prices. But what about the older engines we’ve been using straight 40W Delo 400 and other single-viscosity products in for years? Can we
Even well-made splices in wiring can wick up moisture, especially if they are in a boat’s bilge. Wicking, of course, can cause corrosion, prematurely ruin a splice, and cause electrical issues. To prevent this sort of thing, I suggest adding a drop or two of oil to a splice before you crimp, heat-shrink, or otherwise seal it. The
In this less-than-perfect economy, many people are keeping their current boats and upgrading them in various ways. One smart investment to improve your comfort and your boat’s future resale value is adding or upgrading air conditioning. This
When working in tight spaces with a cordless drill and stainless steel fasteners, here’s a helpful trick. If you can’t hold the fastener with one hand and the drill with the other, use masking tape to secure the fastener’s head to the driver bit so you can proceed single-handedly. Pull the tape off before sinking
The owner of a Bertram 700 wanted to relax while at anchor in cool, quiet comfort. The cool part was easily covered thanks to a Marine Air chiller system comprised of four modular
Question: I own a 1996 43-foot Hatteras with twin six-cylinder Detroit Diesel engines. I change the oil approximately every 100 hours of operation. At this point, I have 1,200 hours on each diesel and so far have only used non-synthetic oil. Is a synthetic or a blend of synthetic and regular oil contraindicated for this aged engine for any
Seeing a yacht in a shipyard is like seeing a dolphin at Sea World—it’s not an entirely accurate representation of behavior in the wild. So when I heard that the 208-foot Polar Star had been released back into the wild after five
Virtually everything can be improved—that’s the point Capt. Matt Condon was making just before the big brainstorm hit him. Condon’s the head guy at Signature Yacht Shares, a Destin, Florida-based outfit that’s into a variety of marine
I’ve got a great tool for topping off batteries. Attach a length of clear plastic hose to each end of a gas-line squeeze bulb. Next time you’ve got low distilled water levels, simply insert one end in the jug and squeeze. You’ll be able to control the amount of water going into each cell and keep from spilling and/or over-filling while pouring directly from the jug.
Question: I have a 29 Phoenix with twin, 1984-vintage, 170-hp Yanmar diesels with 1,000 hours on them. While the boat seems to run fine, I have one issue. During operation, the temperature of each engine rises normally at first but then keeps on going, not to the point of setting off alarms, but close. Pegging the engines (i.e., throttling them
