The Kadey-Krogen 58 at 8 knots gets about 1.64 nautical miles per gallon (6.3 liters per nm) powered by twin 158-hp John Deere diesel engines. In her length and weight category, no recreational boat on earth gets more miles per gallon. How does she do it? The answer is somewhat complex, but basically it is because she is a well-designed displacement cruiser. Displacement cruisers are the boats that most people who want to do serious long distance or transoceanic travel choose. If adventuresome folks are looking for a production displacement fiberglass boat, they only have a few choices, and Kadey-Krogen is one of the most formidable. It has been building motoryachts since it introduced the famous 42-footer in 1977. The company’s boats are designed to be live-aboards as well as LRCs, and that adds another degree of complexity to their design.

Kadey-Krogen 58 (2009-) Captain's Report

Kadey-Krogen

The Kadey-Krogen 58 displaces 96,830 lbs. (44,014 kgs.) at half load. Her best cruising speed is about 8 knots. Get used to it friends, because as Baby Boomers start hitting 65 you’re going to see a lot more displacement boats on the water.

Believe it or not, the average Kadey-Krogen buyer spends two to three years doing research before actually making a decision and opening the checkbook. Then, after buying the boat, an owner holds on to it for seven years, rather than four years or so, which is more typical. So it is a long process on both ends of the sale.

This is the kind of modus operandi is more typical of sail boaters, but most Krogen buyers these days come from the hallowed ranks of power. We were told that the previous boats owned by Krogen buyers were Vikings, Sea Rays, Grand Banks, catamarans, sailboats, runabouts of all brands, and even megayachts. One owner has two Krogens – one on each coast. Clearly, what all these owners have in mind is a different life-style and a different way of boating.

Kadey-Krogen

This is the Kadey-Krogen 58. Most Krogen owners are couples who do most of their cruising alone, with another couple dropping in just now and then. Therefore they prefer just two staterooms with the guest cabin used as an office/library/lounge most of the time.

Gentlemen, Start Your Generators...

“Our owners aren’t show-offs,” says John Gear, President and one of the three working owners of Kadey-Krogen. “They don’t seek notoriety, they eschew glitz. They just want go wondering along enjoying themselves.”

Most Kadey-Krogen owners live on their boats six months a year, using them very much like a summer home or a winter ski chalet. Some live on their boats full time and even work from their boats. Their owners are not the type of people that park their boats behind the house as a status symbol or only use their boats a few times a year on sunset cruises or weekend jaunts. And Krogen owners prefer to anchor out, we’re told.

Displacement Speed, Scotty

We can well understand how long it takes the average powerboat owner to get his head wrapped around going 7 to 8 knots. Note that we did not say 13 knots, or even 10 or 11 knots. When it comes to Kadey-Krogen there is no sugar-coating the speed subject, or hemming and hawing, or “if we put the big twins in…” The number, folks, is 7 to 8 knots. And for most people we know, that takes some getting used to. It’s called displacement speed, and to some people it is a dirty word.

If you thought displacement speed was 1.34 x the square root of the LWL, we’ve got bad news: it is not even that fast. At that speed you are running up against the stiff resistance of your own bow wave and to attain that speed in a displacement vessel is only to squat your stern and burn a lot of fuel for an extra tenth or two of a knot. A more realistic ratio is between 1.1 and 1.2 x the square root of the LWL. Robert Beebe in his groundbreaking book “Voyaging Under Power” had that ratio right, and a lot of other things right, as well.

We like the Freeman, dogged down, hatch to the chain locker to port of the anchor windlass and the two ventilation hatches to the master. We’d put a larger tender aboard and make the vents in the swim platform bigger or go with a teak grate.

Displace What?

What is a “displacement boat,” anyway? Of course all boats displace water, so why is a displacement boat any different? It is different because it cannot plane, nor can it even rise up and become a semi-displacement boat. A displacement boat just moves along in the water pushing aside a volume of water equal to its own weight and as long as you don’t ask it to go faster than 1.1 or 1.2 times the square root of its LWL, it can do that with a low exertion of horsepower and a relatively small amount of fuel.

Slow Down, You Move Too Fast...

Now, why would anyone – except a sailor – want to go so slow? The answer is, in a word: lifestyle. Many people, it seems, come to a point in their life when they gotta let the morning last, so to speak. And the real dream is not racing across the sound to tie up at the Crab Shack before the crowd arrives to get the Happy Hour Special. It is not even to go cruising from one marina to the next in the company of 20 or 30 other boats from the yacht club. It is to live one’s real dream which might be… just kickin' down the cobblestones, lookin' for fun, and feelin' groovy.

For Kadey-Krogen owners, that dream involves living on a boat for six months or more a year. In most cases it also involves long cruises; not necessarily trans-oceanic cruises, going around Cape Horn, or powering to Tahiti, but cruising to Alaska, the Sea of Cortez, Nova Scotia or the Caribbean – cruises of 1500 miles or so, one way. Let us say many of the Krogen owners cruise 3,000 or 4,000 miles a year.

According to Larry Polster, V.P. and one of the three men who own the company, Kadey-Krogen owners actually do with their boats pretty much what they had dreamed about doing in the first place. That is to say, there is no pile-up of Krogens in San Diego or Key West as there were double-ended sailboats 20 years ago when all the chest-thumping sailors who planned round-the-world voyages got cold feet when it came time to actually taking the plunge.

Cruising Speed...

Now in a 60’ planing something you can cover those 4,000 miles going 25 knots, burning, say, 80 gallons an hour. You could do it at the same speed in an 85’ motoryacht burning 150 gph. With fuel at $3.50 per gallon ($8 per gallon for Europeans) that means you’ll be spending plenty on fuel in the U.S. (let’s see, at $8 per gallon in Europe...we don't want to know.)

The Kadey-Krogen 58 at 8 knots can cover the same ground for $2k in fuel. And engines that go fast that are used hard tend to have more problems than engines that are smaller and that run slower. So the cost of operation may play a big part in a buyer’s decision.



(Ironically, displacement yachts are not popular in Europe. After all, that is where Azimut, Sunseeker, et al come from. Go to the big yacht marinas along the French Riviera and you can count the trawlers in each marina on one hand. But now you know why most rarely leave the dock.)

Kadey-Krogen

The galley aboard the Kadey-Krogen 58 and the other models as well are the one place on where most of the customization takes place. Note the Viking-type propane gas stove/oven and dual sinks. The company also puts in the full size Jenn-Air French door refer/freezer which we recommend. We’d make the counter fiddles higher.

Displacement by Any Other Name...

Are all displacement boats the same? No. The bottom shapes vary to a great degree. The Kadey-Krogens, for example, have a sharp entry which makes it easier for their boats to part the water for that displacement hole they are going to make. At the other end of the Krogens, the buttocks have a slight V-shape that the company says makes them better in a following sea as well as reducing stern wake drag. Its bilges are rounded to make the boats sea-kindly, but not too round, because they need form stability. And because they are displacement boats they are not terribly sensitive to wetted surface as a planing hull would be. The Krogens have a keel infront of the prop, or in the case of twin-screw vessels, in front of both props.

The issue of propellers is another place where displacement boats have a distinct advantages over boats with running gear hanging under the boat unprotected. Damaged or fouled props are among the biggest problems of inboard-powered boats, but not so with props protected by a keel, skeg and shoe. While most displacement motoryachts have this protection, few builders let you pick a single engine or twins, as does Krogen.

Relevant Distinctions...

Do all displacement boats which have the same speed/length ratio and horsepower also have the same actual speed and fuel consumption? No. Heavier boats of an equal footprint in the water will obviously sink deeper, and for every inch deeper a hull sinks it has just that much more water to push aside to make way for its displacement hole. So the old saw about weight not making any difference in a displacement boat is not entirely true. A large difference in weight does make a difference in speed and in fuel efficiency among displacement boats.

Kadey-Krogen

The main saloon of a Kadey-Krogen 58. Krogen allows a surprising amount of customization without an extra charge. No two Krogens are exactly alike – but all Krogens have plenty of bookshelves. (Yeah!) The galley is behind the half bulkhead.

Shape Matters...

Another way that displacement hulls are different involves the shape of their bow and forefoot. A hull with a blunt bow has to push the water away very quickly to pass through, and this high acceleration requires large amounts of energy. By using a fine bow, with a sharper angle that pushes the water out of the way more gradually, the amount of energy required to displace the water will be less, even though the same total amount of water will be displaced.

A third way to get more efficiency out of a displacement hull is to add a bulbous bow. These are used nearly universally on large commercial ships to reduce wave making drag. The bulb alters the waves generated by the bow. On the 147’ megayacht Marco Polo, the owner reports that after over 40,000 miles of operation he could conclude that the bulbous bow added 10% to the efficiency of his single-engine vessel. Papers on the Internet on the subject say they give from 12% to 15% more efficiency to large commercial vessels. Wikipedia says bulbous bows are effective on boats over 50’, but Tom Button, Kadey-Krogen’s VP of operations and the third working owner, says they he has studied bulbous bows and finds that they only begin to become effective on boats over 75’.

How to Cruise Fast in a Krogen...

There are other ways that displacement boats can even up the score on long passages. For example, large convertibles and some motoryachts boats going from Florida to New England can cover the 1,000 mile distance in six days. Each evening they must stop in at a marina with a fuel dock and tank up (700 to 1200 gallons – 2660 to 4560 liters -- typically), wash the boat down, have a big dinner, then go to bed early to be ready for the next day of pounding along offshore at 20 to 25 knots. On deliveries these boats usually carry two or three people aboard.

On the other hand, a displacement vessel with three crew aboard, can run offshore 24 hours a day, and make the whole 1,000 nautical miles easily on about a half a tank of fuel in five days – one day faster than the hot shots! Not only will the displacement boat owner save money on fuel and oil, but also on marina dockage, tips, and big crew dinners. And, they only have to wash down the boat once!

Kadey-Krogen

All Kadey-Krogens have large double-doors that are metal and dog down, are water tight and are leading to the aft deck. This is something that you rarely see on any motoryacht of any size or price. Note overhead grab rail (all motoryachts should have them). Note details that were customized per this owner's wishes such as the valances and A/C grate.

Watch Your Flowers Growin’...

More likely, the owner of a Kadey-Krogen would put in every night simply because their owners are not in a hurry. They would probably decide that while they can make the Miami to New York run in 12 days, stopping each night, they would rather make the passage in 30 days, staying in fun places like Savannah, Charleston, and the Eastern Shore of Maryland for more than an overnight. Then there are the great creeks and bays of the sea islands down in Georgia and South Carolina...

People who buy displacement vessels in general, and certainly Kadey-Krogens, have a different tune playing in their heads...and they are feelin’ groovy.




Fifty Ninth Street Bridge Song (Feelin' Groovy)

By Simon & Garfunkel




Slow down, you move too fast

You gotta make the morning last

Just kickin' down the cobblestones

Lookin' for fun and

Feelin' groovy




Hello lampost

Whatcha knowin?

I've come to watch your flowers growin'

Ain'tcha got no rhymes for me?

Doo Bee Doo Doo,

Feelin' groovy




Got no deeds to do

No promises to keep

I'm dappled and drowsy and ready to sleep

Let the morningtime drop all its petals on me...

Life, I love you,

All is groovy
