Eleven Green Boating Tips


Soon after a boat passes, its wake has vanished. But as boaters we do impact the waters we love, and there are ways to keep our “wakeprints” invisible. Anglers, it seems, have a special stake. They have extra potential to have negative impacts through bait, gear and fillet knives as well as a special interest in keeping waters and their inhabitants healthy. But all boaters have both the opportunity and the responsibility to leave their waterways and world as unsullied as possible. Fortunately, it’s not as painful as it sounds. Often, going green and boating in a thoughtful way makes it more pleasant, more affordable and more fun. Start with these 11 tips:
1. Repel Invaders
Help keep invasive alien species — both plants and animals — from spreading. Clean and dry your boat and trailer between outings. Don’t move live fish from one body of water to another. Dispose of bait properly — not in the lake.
2. Keep Your Head, Properly
Whether it’s an installed, plumbed head or a portable potty, don’t shortcut the pump-out process. No head? Liners and seats are available to turn a five-gallon pail into a “throne.” It’s not fancy but it is functional and lake-friendly.
3. Clean Cleanly
Use environmentally friendly cleaners where possible — white vinegar to kill mold, for example. Tough tasks may call for tough tools, but always go as mild as the job allows.
4. Maintain Your Motor
Get regular tuneups, fix leaks and clean up spills. That all minimizes the escape of fuel and lubricants and — as with many green ideas — it saves you money too via lower operation and repair costs.
5. Replace Your Engine
Aspirated two-stroke engines not only burn oil, they let some of the oil/gas mixture escape between firings. Direct-injection two-strokes and four-stroke engines operate much cleaner. As a result, you might consider repowering a used boat.
6. Watch Your Wake
Besides irritating others, threatening damage to other boats, and maybe even creating a hazard, waves can cause erosion of fragile shorelines. When boating through delicate areas, take it easy.
7. Talk Tackle
Fishing line and other lost tackle, including soft baits that fish might eat, last virtually forever. Losses happen, but don’t add to the situation by carelessly tossing overboard stuff you’re done with.
8. Cut Commuter Carbon 

Stay an extra night! You’ll feed the boat its daily oats but drive time and cost will remain the same, yielding more boating per highway mile and carbon footprint. Check trailer tire pressure, and find the highway speed that burns the least fuel.
9. Harvest Deliberately
Nothing’s better than a mess of fresh-caught fish, but think twice before taking a hefty harvest if the fillets are only going to sulk in a freezer until defrost time. Catch and release? Do both quickly, with a snapshot in between.
10. Learn the Rules
Nearly all boating and fishing rules are written not to hassle us, but to keep us safe and protect the environment in which we pursue our boating pleasure.
11. Goodbye, Old Paint
Anti-fouling coating is serious business on a boat, but there are new water-based, environmentally friendlier ways to do it with no odor, fumes or solvents. Clean up with soap and water, and watch for similar advances in other boating supplies.

Saltwater Rods and Reels


Spinning Rod and Reel

These spinning reels feature heavy-duty gears and drag systems for battling bigger fish. Spinning rods are available in medium to heavy action and range in length from 7 to 10 feet long. Saltwater spinning tackle is popular for working topwater poppers and high-speed plugs and casting lighter lures.

Saltwater Baitcasting Rods and Reels

Baitcasting tackle is ideal for throwing swimbaits and plugs for bluefish, snook and other inshore species. Baitcast reels can handle a large capacity of line ranging from 15- to 20-pound test and gear ratios as high as 7.0:1. The best casting rods feature a fast taper and heavy backbone. Freshwater baitcasting tackle is often used in saltwater. Some are manufactured to be more corrosion resistant to salt.

Saltwater Trolling

Saltwater trolling reels use a lever drag system rather than a star drag, which allows quicker adjustment of the drag with the lever on the side of the reel. Trolling rods are short and stout with a notched butt that fits into a gimbal on a fighting belt or chair.

Saltwater Jigging Rods and Reels

Saltwater jigging tackle consists of a spinning or casting rod with a springy tip. Spinning or baitcasting reels with heavy drag and large spools are capable of holding hundreds of yards of braided line. Vertical jigging requires high-speed reels with gear ratios of 6.1:1 or faster

How to Buy a Water Ski


Whether you’re buying your first water ski or simply upgrading your current setup, finding the perfect ski for you has never been easier. More than ever before, manufacturers are tailoring their lines to suit the skiing style and ability level of every potential skier out there. As a result, when armed with the knowledge of your particular needs, you can purchase your new ski with complete confidence and no remorse.

Pick Your Pro Shop

The first step toward retail bliss is finding a pro shop with a knowledgeable staff of skiers. Discussing your ability level and your goals with a reputable pro-shop staff will ensure you’re purchasing a ski that is properly designed and sized for your particular needs, so your skiing can progress with minimal resistance.

Find Your Niche

Manufacturers are no longer attempting to stuff every skier into a box based solely on their ability level. Differing skiing styles and water conditions are now as important as the skier’s experience level.

Course Skis

This style of ski is aimed at more experienced skiers who spend the majority of their time skiing the slalom course. You don’t need to ski 100 days a year to appreciate the benefits of these carbon-fiber high-performance models, but they are designed to be ridden at higher speeds, in controlled environments, and on calmer waters. Course skis feature adjustable fins that allow you to customize their performance characteristics to your particular needs, and they’ll be paired with custom-fitted bindings for maximum control.

Freeride Skis

This is a relatively new genre of ski that has replaced the traditional shaped/beginner skis. Freeride skis, while easy to get up and learn on, are focused on performance. Reactive materials and new bevel designs allow these skis to turn and hold angle with ease, catering to the widest range of ability levels. Skis in this class are designed to be ridden at slower speeds and in varied water conditions. Freeride skis will typically feature a standard or shaped fin that will perform in conjunction with the design of the ski.

Youth Skis

This class of ski encompasses both course and freeride designs, and youth skis will feature many of the construction materials and design ideals of their more mature predecessors. Not simply shorter, today’s youth skis sport softer flex patterns that let your young, lightweight skier turn the ski as its shape was designed. Manufacturers are also focusing on expanding their high- and mid-performance boot lines into youth-specific sizing.

Combo Skis

Let’s make learning to water ski easier than ever before: This seems to be an industrywide mantra in recent years, and this goal is clearly illustrated in entry-level combo skis. This is the easiest category in which to select your skis, because nearly every manufacturer makes a quality set of skis to learn on. Additionally, entry-level-shaped and anatomically correct bindings help hasten a new skier’s learning curve like never before.

How to Lasso a Piling


With practice, you should be able to lasso a piling with a mooring line from, say, 8 or 10 feet off. There are, of course, times when even the most talented skipper will thank you for saving his boathandling bacon with this skill

How to Lasso a Piling

Following are the step to do it. Start by
  1. by forming a large loop in the end of your mooring line (either with a bowline or by pushing the standing part through the eye at the business end of the line) and then holding one side of the loop and the standing part in both hands
  2. sort of like a boathook. Now swing back and to your right with both hands and throw the loop while imparting a bit of a spin
  3. thereby giving it a circular shape.
  4. The trick? Keep your eyes on the target all the time.

New 370hp Mercury diesel engine: pros and cons


Mercury Diesel's new twin turbo 370hp TDI 4.2 is the first production marine engine to boast a better power-to-weight ratio than its petrol-powered equivalent.
Mercury Diesel’s new twin turbo 370hp TDI 4.2 is the first production marine engine to boast a better power-to-weight ratio than its petrol-powered equivalent. Based on the all-aluminium V8 block designed by German car manufacturer Audi for its A8 and Q8 models, this marinised 370hp powerplant is claimed to set new benchmarks for size, weight and refinement.
Tipping the scales at a mere 379kg it is over 200kg lighter than Volvo Penta’s equivalent 370hp D6 diesel engine and even undercuts Volvo’s 8.1-litre petrol V8 by 10kg. It also has a smaller footprint than any big-block petrol or diesel engine. Petrol heads will argue that the petrol engine’s higher maximum power output of 420hp evens the score but with marine engines torque is the more siginificant figure and by this yardstick the 572ft/lbs (775Nm) of torque produced by the TDI 4.2 at 2,500rpm is unmatchable.
More significantly this engine produces a punchy spread of power from 2,000rpm all the way up to 4,200rpm. Such wide power bands are unheard of for marine diesel engines with most of the good work happening between 2,000-3,000rpm. Petrol engines meanwhile suffer the opposite problem with maximum torque not kicking in until 3,000rpm.
Whatever measurement you choose, the new Mercury TDI 4.2 stacks up well against its closest diesel rivals, the Yanmar 8LV-370 and the Volvo D6 370. The Yanmar weighs in at 450kg, hits a peak torque of 590ft/lbs at 2,200rpm and is red lined at 3,800rpm. The Volvo weighs in at 580kg, reaches a higher maximum torque of 650ft/lbs at 2,000rpm but runs out of steam earlier with a red line of 3,500rpm. However, the real crunch figure for smaller sportscruisers is the 400kg weight saving which a pair of TDI 4.2s would give you over twin D6s.

New 370hp Mercury Diesel Engine 

Mercury Diesel attributes the TDI 4.2’s wide power delivery to the use of twin variable-vane turbochargers. As the name suggests they work by adjusting the angle of the vanes within the turbocharger to maximise boost pressure at low revs and reduce turbo lag. At low rpm the vanes close up, meaning the exhaust gas has to force its way through the small gaps at speed, causing the turbine to spin rapidly even with low exhaust gas pressure. As the revs increase, the vanes open up to maintain the same level of boost without fear of overloading. Variable-vane turbochargers have proved very effective in cars but have been problematic in some marine installations due to relative lack of use.
The long stroke construction of the engine is another torque booster. A long stroke means a long conrod increasing the amount of energy transmitted to the crankshaft. The TDI 4.2 has a stroke-to-bore ratio of 1:15 meaning the stroke is 15% longer than the bore is wide. In comparison the 370hp V8 Yanmar 8LV-370 has a stroke-to-bore ratio of 1:11. The downside of a long stroke is greater piston speed resulting in increased friction. However this problem only comes into force at engine speeds well above 5,000rpm so this will not inhibit the TDI 4.2.
The new Mercury Diesel TDI 370 is available with either a MerCruiser sterndrive or a ZF gearbox for shaftdrive applications. The sterndrive options are Bravo 1, 2 or 3 in either X or XR formats. All feature the SeaCore corrosion protection system. SmartCraft comes as standard enabling the TDI 4.2 to be interfaced with all digital Mercury instruments. DTS (digital throttle and shift) and the Axius joystick system can also be specified. Scorpion is already offering it as an engine option on its range of performance RIBs but expect many other power boatbuilders to list the TDI 4.2 as a factory-fit option soon. A 335hp version will also be available. All engines are Tier 3 compliant and available for light duty commercial as well as leisure use. Prices start at £41,000 including VAT with the Bravo 1 XR sterndrive.
