AWSA Water Ski Towboat Tests

I ran across some the test scores that AWSA used to share back in the good old days of AWSA Tow Boat testing.  Seems the Hydrodyne Outboards which are 15 & 16 on the list below had the best total scores.

We have not changed the hull shape although the new style Dyna-Ski 20' hull running surface is about 9" longer than the old 20' Hydrodyne. The 9" was added near the back end on the hull.  The deck's of the Dyna-Ski Boats are much different than the Hydrodynes of old.  We still use the original hull mold for the 17.6 models. I think that the 17.6 also was an approved tow boat in 1986.  The outboard motors now are more powerful as they went to measuring the horsepower at the prop instead of the crankshaft in 1991. I'm going to look thru my stuff and will share some of the interesting things in the future.  Below is an enlarged and cropped version.  The complete scanned form is on the bottom of the article.

Dyna-Ski 17.6 Open Bow Barefoooting Pictures

Here are some pictures taken a couple years ago.

Outboards, back in?

Katharine McPhail of  www.travelboater.com wrote the following article a couple years ago. She wrote it for WaterSki Magazine but they never published the article.


Are you a serious skier who can’t stomach the price of an expensive inboard boat, consider the alternative: a tournament style outboard. For less than half the price, an outboard ski boat can offer some pretty sweet advantages.

Dyna-Ski, a tournament style outboard based off the classic hull design of the popular Hydrodyne, can be equipped with motor and a trailer, starting in the low $20,000 range.  The size of the motor significantly influences the final cost of a boat, but even a fully optioned 20’ open bow Dyna-Ski will stay priced around $40,000.

This is a smart investment for the budget conscious water skier.  Outboard motors typically use less fuel than the V-8 engines in most inboard boats.  When you consider the power it takes to pull a water skier all morning, this can add up to substantial savings beyond the boat’s already lower sticker price - an advantage that gives you more ski-time for the same amount of money.

With outboard motors now just as clean and quiet as any inboard, easy maintenance is another advantage. The diagnostics and repair of a motor that hangs off your transom is much easier than a motor buried in the hull of your boat.  Plus, as outboard technology continues to develop, you can modernize your boat by simply replacing the motor rather than the whole boat.

But what about performance, how does it compare to an inboard?

The wake on a Dyna-Ski is similar to an inboard boat, only smaller.   Pete Pfankuch, the owner of Dyna-Ski noticed, “a smaller wake is often preferred by women and kids - since the bow of the boat stays down at all speeds [Dyna-Ski] is an excellent boat for pulling any size, age and level of skier at speeds up to about 50 mph.”

Outboard ski boats allow for added horsepower - an advantage that makes them a good towboat for all disciplines of water skiing. Eric Nelson, the boat driver and Vice President of the Beaverland Must Skis (a Wisconsin ski team) vows  “there is no better boat for a Water-Ski Team.”

And Nelson would know. His team owns five outboard boats - four Dyna-Skis and one older Hydrodyne. In September of 2006, a Dyna-Ski rigged with three 225hp E-Tecs, had enough umph to pull 48 skiers stacked four-tiers high - a feat that put the Must Skis and three other Wisconsin Teams in the World Record book.

Even if you’re not attempting to break world records, Dyna-Ski is a good option for the recreational user as well.  The boat will accommodate friends and family who want to tube, wakeboard, trick ski, slalom or barefoot.  And options such as pylons, booms, towers, and fat sacs can be added to suit the serious skier. In fact, Dyna-Ski is currently working with mechanical engineers to designs a device that will further improve the wake for wakeboarders and barefooters.

In this economy, value is a principal concern, but a smaller budget doesn’t mean you have to compromise on quality.  If you’re pinching your pennies, but still want a high performing tournament style ski boat, take a second look at outboards, especially Dyna-Ski.  See how newer motor technology on the back of a classic hull design can benefit your wallet and your skiing experience.
