Scat Info

I put this page together to help prospective Scat Hovercraft owners... 

I hope this information helps! It seems that there are a lot of inferior craft flooding the used market lately, and some not so scrupulous people trying to sell them to unsuspecting newcomers to the sport. 

     The deck portion of a Scat is fiberglass with a "Gel- Coat" finish... In other words if it's in "good shape" it should look like the finish on a speedboat! Paint is NOT a good thing! It was painted for a reason, and most of the "reasons" aren't good.

    The Hull of a Scat (Who on Earth knows why!!) is ABS plastic... Easy to mold I guess, but as far as being an impact bearing surface there are much better! The stuff will actually take a pretty good hit, but then it cracks. As it get colder ABS gets more brittle. Prime areas of damage are the transition areas from the planning (sloped) surfaces to the flat bottom- Remember this is not a car! It can fly just as fast sideways or backwards and wack into something as it can going forward! There are no brakes and this does happen- especially to beginning pilots. Another bottom feature on the Scat to really check out are the 3 aluminum "skids". Hit these babies going sideways with any kind of speed over a hard surface and they will sometimes catch and stop.... either you go tumbling out onto the ground, or something breaks, or both. Check on the condition of the skids, and the area around them.

    It's MUCH easier to buy a good specimen to begin with than it is to spend all kinds of time, money and effort fixing up your new toy before using it! The cracks can be repaired by plastic welding, ABS cement, and some people have had luck laminating the whole mess with fiberglass- like I alluded to.... it's more fun to fly than it is to fix!

    Skirts? Scats use "finger" skirts.. not some bodged hoop of fabric resembling a "bag" skirt. There is one finger skirt for each air hole in the hull... we're talking in the neighborhood of 60 some odd skirts depending on the model. The Skirts are available from either Saint Louis Hovercraft or From GPL.

    Bigger motors are better!!! Horsepower is your friend!

   

This is how the skirts should look on a "proper" Scat... In this case it's a Scat 12HP which is 12' long and powered by a 64 horsepower Rotax 532... Yes it did fly all 3 of us... The Scat 12HP is rated for 700 lbs.. these things ARE Coast Guard rated and do have a certification plate (just like a boat!) up near the steering area.  In the picture above  I'm about 190, my son is about 200 and his friend goes about 160. We flew about 40 miles that day.

  

Back side.. the white "P" clips at the bottom edge are where you would attach the bottom sides of the segmented skirts with 50#(breaking strength) nylon wire ties.... one skirt per air hole! The top of the skirts is folded over the top of  the aluminum strip that you see between the deck and the hull where it is attached with 3 clips per skirt . There is a "U" shaped trim piece that goes all the way around the craft that covers the top edge of the aluminum and the clips. Notice no hull cracks! Also notice the landing skids... which are made of aluminum channel.

This is a front view... watch the area around the skids, and the edge were it transitions to the flat bottom.

This is the back side again... a closer look at the rear transition area... Hovercraft fly backwards and sideways too so all transition areas to the flat bottom need to be looked at!

Side view... no cracks, skids in good shape, no cracks around the skid supports, no cracks at the "P" clips, "P" clips are all in good shape, Aluminum skids are in good shape

Side view... farther out...

Good Luck!!!

Any more questions let me know....
