Trade was a hot issue during the Obama Administration and continues to be a hot issue during the Trump Administration. Very smart and well-intentioned people have differing perspectives on free trade and the geopolitical perspectives are seemingly endless. While it is an emotionally charged issue, most economists agree that on a macro level trade is beneficial to those who participate. Sometimes the benefits are disproportionate or occur at different times, making them seem inequitable, but free trade almost always helps those who participate.

As U.S. manufacturers we, of course, want free trade agreements to be beneficial for U.S. companies, employees and the country in general. Free trade can help U.S. companies and employees by reducing protective tariffs in global markets allowing U.S. manufacturers to sell our products around the world at lower prices which generates jobs. Free trade also helps U.S. consumers by giving them access to a larger variety of products at lower prices. Additionally, free trade agreements can help level the playing field by requiring our foreign trading partners meet (or at least get closer to) U.S. labor and environmental standards. This not only levels the playing field, which makes doing business more equitable for U.S. companies (which creates U.S. jobs), it also helps both the environment and a lot of workers around the world. The potential benefits of free trade are not just financial.

The arguments against free trade include national defense concerns, which are legitimate for certain products, but are primarily focused on concerns about American jobs. Some smart people argue that if we allow free trade there will be situations where U.S. companies are challenged to be competitive with foreign businesses, which may threaten some U.S. jobs. This is a legitimate concern and can be understandably scary to people in vulnerable industries. We should do what we can to make sure trade is not only free but fair, and after that we need to help people who are negatively impacted.

However, we should also take a long-term view when trying to figure out how to create the most U.S. jobs in the decades ahead. The world is changing whether or not we participate and we need to be competitive in the global marketplace. While artificially protecting industries/companies can mitigate short-term disruption for some, it often has costs and loss of benefits for others. When the U.S. places tariffs on imported goods, they are not actually paid by the foreign importer – they are either paid by the U.S. consumer who purchases the goods or they limit U.S. consumer’s access to goods.

Globalization can be unsettling but capitalism has taken root around the world and many regions accross the globe are becoming much wealthier because of it. This is good for many people around the world and is going to continue whether or not the U.S. participates in more global trade. Ninety-five percent of the world’s consumers live outside the U.S. and the world economy will continue to expand with or without us, so we need to find the right balance and grow with the world economy.

Finally, free trade can be the difference between war and peace. Related to that, I recently read the book Economic Interdependence and War by Dale Copeland, a University of Virginia professor. Dr. Copeland researched the world economy since 1790 to determine how trade impacts the likelihood of a country going to war. As a result of his findings he developed his “Trade Expectations Theory” which states, in summary, that if countries are optimistic about future trade together they are much less likely to go to war. This is interesting to think about as we look at the current geopolitical landscape and particularly related to the U.S. relationship with China (who has stated a desire to step into any global vacuum left by U.S. protectionism).

I have traveled to over one hundred countries and know that the U.S. is respected and “Made in the USA” means something – people around the globe want our products and specifically our boats. We can still build the world’s best products at competitive pricing. History has demonstrated that protectionism does not work in the long-run, but free trade can increase wealth for everyone.

Our industry has historically supported free trade and, while we clearly need to ensure our trade agreements are equitable, I hope we will continue to embrace the global trade challenge and move forward confident that we can compete with anyone.

For the third consecutive year, Frank & Jimmie’s Propeller provided NMPA’s Design, Build & Race Your Own Propeller Program to Ft. Lauderdale High-School students.

With sponsorship from the Marine Industry Cares Foundation, students from South Broward, Dillard and Stranahan High Schools attend the Marine Industry Immersion Summer Camp.  The two-week program introduces students to opportunities in the recreational marine industry, which pays 28% higher wages than the Florida State average.

The highlight of the program is, of course, propeller racing!  As those of you who attended the 2016 NMPA Annual Convention in Las Vegas may remember (after all, “what happens in Vegas…”) we had our own Design, Build and Race Challenge poolside at the Orleans Hotel.  NMPA Members are encouraged to sponsor their own DBR Challenges in their communities to introduce and promote the propeller repair and marine industries.

Jimmie Harrison, of Frank & Jimmie’s said, “Providing high school students access to the businesses and leaders of the marine industry while showing them the opportunities in the propeller repair business is critical for the growth of our trade.  Frank & Jimmie’s is thrilled to be doing its part to help grow and secure the industry’s future.”  In addition to the Summer Camps, Frank & Jimmie’s hosts propeller racing at Ft. Lauderdale’s Annual Marine Industry Day and Plywood Regatta, now in its 21st year.

“This summer, nearly 100 students will design, build and race their own propellers in Ft. Lauderdale,” said NMPA managing director Gordon Connell.  “With the addition of an extra day of teaching and head-to-head competition, students have time to modify and adjust their designs and assess the tradeoffs between propeller diameter, blade areas and pitch on speed and performance.  Combined with a tour of Frank & Jimmie’s Repair Facility, they get a real-world feel for propeller design, build and repair.”

In addition to providing NMPA’s Design, Build & Race Your Own Propeller Program at venues throughout Ft. Lauderdale, Frank & Jimmie’s also employs two high-school summer interns from the Broward County Public Schools and sponsored a third high-school student/part-time employee in his participation in SkillsUSA, a local, state and national program for students to develop and demonstrate personal, workplace and technical skills grounded in academics. Ricardo “RJ” Perez won the local and state welding competition and is on his way to participate at the national level.

“Our #1 focus every day is on our employees – both current and future,” said Don MacRae, Frank & Jimmie’s President and COO.  “At Frank & Jimmie’s, recruiting, hiring, training and developing employees is our #1 priority.  Our local high school students are a vital component of our future employee pipeline.  It is exciting to see the interest these students have in our business when they’re given the opportunity to learn in a fun environment.  Today’s students are the repair professionals and business leaders of the future; the Marine Industry Cares Foundation does a great job providing summer camps so the students can learn about the marine industry and the tremendous opportunities that exist right here in their own backyard.  That itself is reward enough…”

Years after the space race, propeller design remained a sea-trial-and-error endeavor: haul, tweak the props, relaunch, sea-trial, repeat. Finally, the U.S. Navy paid the Massachusetts Institute of Technology to predict propeller performance using a computer.

The resulting 3-D computer models let Navy experts alter and analyze blade skew, rake, chord length and camber to maximize ship speed while minimizing noise. After the Cold War, those Navy/MIT propeller design tools became available to the private sector and, within the past 10 years, once-top-secret designs have made it to off-the-shelf production props for inboard boats as small as 35 feet.

Will a set of high-tech props increase your boat’s speed or economy, get it on plane faster, or even make it handle better? I persuaded four prop experts to share their thoughts with Boating.

The Plane Truth
“A propeller is really just a set of rotating wings,” says Greg Platzer, who headed the surface ship propeller group for the U.S. Navy through the latter part of the Cold War. Platzer’s team curved propeller blades like airplane wings. This spread the load across the entire propeller, maximizing efficiency, minimizing cavitation and producing quieter props that were harder for enemy submarines to detect. Now a civilian, Platzer designs custom propellers for large yachts. “On yachts, we’re using the same principles for different reasons,” he says, citing props that deliver 5 to 10 percent increases in fuel efficiency and/or speed while cutting vibration by up to 75 percent.

Best For Which Boats?
“A 30-knot [34.5 mph] boat that has steep shaft angles is an ideal candidate,” says Jimmie Harrison, president of Frank & Jimmie’s Propeller in Fort Lauderdale, Florida. “We’d expect to see a knot or two more speed at top end with the correct foil-shaped prop blades.”

That’s not to say new props won’t do anything for slower boats, but there are more variables. “On a boat cruising around 18 knots [20.7 mph], where it’s just on plane, the right propeller design can mean a world of difference — maybe a 5-knot [5.7 mph] gain,” says naval architect Kevin Mitchell of Michigan Wheel Marine. Mitchell says diesel-powered boats over 40 feet using at least a 2-to-1 gear reduction typically benefit most. “In gas boats, with smaller-diameter props turning close to engine rpm, the best design might be that traditional flat-faced prop with some cup on the trailing edge of the blade,” he says.

As engine horsepower increased over the past decade, ideal prop diameter for a given boat model typically increased as well. But since boatbuilders usually can’t change prop diameter on a venerable design, increased horsepower often leads to increasingly inefficient props. This holds true for boaters who have repowered as well. One solution to the conundrum comes from advanced prop design. “The optimum diameter of a five-blade propeller is always going to be smaller than a four-blade, so we gain efficiency by increasing the number of blades,” Platzer says, adding for emphasis, “With an airfoil-shaped blade, we can increase blade camber to match increased horsepower.”

Handling Benefits
Additionally, boats that benefit from lowering trim tabs considerably at cruise rpm might see big gains from foil propellers. That’s because the downward angle of propeller shafts on most inboard-powered planing powerboats helps propellers lift the stern without the added drag of lowered tabs. Airfoil-shaped blades make it easier to produce lift efficiently. Mitchell recounts an example: “A mainstream express cruiser gained 2 knots [2.3 mph] at top end, with corresponding increases in economy at cruise speed, simply by switching from our older Dyna-Quad design to our new, foil-shaped EQY propeller.”

On the other hand, “If your engines aren’t putting out enough horsepower at the rpm where the boat is coming up on plane, there probably isn’t an advantage to foil-shaped props,” Harrison says, describing the classic diesel-turbo-lag situation. “That problem is often solved with less-efficient propellers that slip more at midrange rpm.”

Plus, propeller blades raked aft increase stern lift by shifting the center of effort of that lift in relation to the fore-and-aft center of buoyancy of the boat. (Yep, inches matter at thousands of rpm.) But the reverse is also true: Blades raked forward or designed for less propeller lift might balance a boat. Often, handling problems, like a boat that tends to stuff its bow into following seas, can be mitigated.

Noise, Vibration and Cavitation
“Propeller noise, and often vibration, is primarily from cavitation,” Platzer says. “We want to unload the tips of propeller blades by changing their shape to control where on the radius of the propeller we produce thrust.” Simply adding blades alleviates noise and vibration too.

“Cavitation typically occurs as each propeller blade passes through the wake of the running gear and close to the hull,” Platzer says. With only three blades, one-third of the prop is passing through that disturbed water at any given time. Increase to five blades and only one-fifth of the prop is subjected to that added cavitation. Adding blades decreases ideal prop diameter, which increases distance between blade tips and the bottom of the boat. “The gains are linear,” Platzer says. “Doubling the tip clearance cuts noise and vibration in half.”

Skewing propeller blades — curving the edges a bit like a banana instead of leaving them symmetrical like a cloverleaf — was one of the Navy’s closest-held secrets for reducing prop noise. “That curved leading edge of the blade passes through the wake of the strut and hull over a longer arc of propeller rotation,” which spreads the effects of cavitation, Platzer says.

On boats with propeller pockets, blade tips are close to the hull over a longer arc, so new props are particularly helpful.

Trimmable Thrust
“An outboard is a blank slate,” says Steve Powers, president of PowerTech Propellers. “One engine model might be used on anything from 20 feet to 40 feet, running at different shaft angles and different depths.” Because of this variety, PowerTech manufactures more than 100 different propeller variations for V-6 outboards.

The driving force behind outboard prop technology wasn’t top-secret Navy data, but tighter emissions requirements that spawned more four-stroke outboards. Heavier engines made boats harder to keep on plane. Four-strokes distributed horsepower differently across rpm and were geared to turn propellers slower. Quieter motors demanded quieter propellers.

“Now with smaller-displacement engines producing more horsepower, it’s even more important to match the prop, motor and boat,” Powers says. The right props best utilize specific engine technology, like variable valve timing or superchargers.

Powers says boats with handling issues are often simple cases of improper propping. Porpoising, for example, is usually mitigated by adding blade surface area and reducing rake. Falling off plane on hard turns, caused when props ventilate (draw in air) is often resolved by changing the blade shape. Less propeller pitch, more blade surface and less rake usually help boats stay on plane at slower speeds. Adjusting blade diameter, number of blades, surface area and rake can also increase fuel economy.

With the exception of pure racing machines, sterndrive boats tend to all be similar, and so are their props. Sometimes a bit of cruise economy can come at the expense of top-end speed, but unless a boat exhibits a specific problem, Powers doesn’t typically see enough gain to justify new props for sterndrives.

Availability and Cost
“At first, we were designing completely custom props for a series of production boats,” Mitchell says of monthslong projects to aid builders in hitting performance targets. Based on those experiences, Michigan Wheel Marine developed automated tools to design semicustom propellers quickly and inexpensively, as well as advanced CNC machining to produce those complex shapes. “This makes sophisticated propellers much more affordable, and performance is much more consistent,” Mitchell says. Where propellers previously might require one or two sea trials with tweaks to find perfection, even on production boats, CNC-machined props typically reach rated rpm and match port and starboard engine load at every rpm the first time a boat is launched.

New propeller technology is available off the shelf too. For around 30 percent more than venerable flat-pitch ­Dyna-Quads, new EQY props with airfoil-shaped blades work particularly well on diesel-powered boats over 40 feet that cruise between 30 and 35 knots [34.5 and 40.2 mph], Mitchell says. Going a little lower tech, many express cruisers in the 30-foot range have three-blade Dyna-Jet or four-blade Dyna-Quad props. For about 10 percent more money than those props cost today, the company’s new DQX series is not a foil shape, but it’s optimized for higher horsepower and newer propeller materials and manufacturing. “Switching from three-blade to four-blade might trade a little top-end speed, but you gain significant efficiency at cruise and smoother operation,” he says.

Maybe Your Current Props Are Wrong
“Sometimes props have been reconditioned so many times, they’re not even the right size anymore, or the boat had the wrong prop design to begin with,” Mitchell says. Boats gain weight as equipment is added, and props are altered with the sole goal of hitting proper full-throttle engine rpm. “Getting the right design and size for the boat can create a huge difference,” he says. Propeller manufacturers can often provide exact parameters to shops with new electronic scanners, like Prop Scan or Hale MRI, so they can reproduce the original prop shape.

And increasing accuracy of repairs might solve propeller problems. “MRI ensures tighter tolerances,” Harrison says. “It also ensures the geometry is the same on each blade,” which is particularly important to reduce vibration. Improving Class 1 or Class 2 repair tolerance propellers to the highest Class S, while tweaking pitch and cup at the same time to better match a boat’s needs, costs about $550 for a 21-inch, four-blade, cupped prop — versus $400 per prop for an ordinary Class 1 or Class 2 repair. This alone can wring more efficiency and reduce vibration from existing propellers.

So how did the Navy’s top-secret propeller design technology land on production-boat prop shafts? “The Navy moved to different technology,” Platzer says, but he won’t elaborate.
