Motorcats

Sitting nicely on the hammer head on A pontoon at Wolverstone for a few days last week (next to the fuel barge diesel @ 0.59 /ltr /forums/images/graemlins/shocked.gif)

Now you have to put up with lots of boats going by including some of the ships going to Ipswich docks, which can make it a bit bumpy at times

the worst buffeting we got was from a frigging motorcat....it seemed to be travelling at or about the speed limit but the wash effect had me running for additional fenders in case he came back again /forums/images/graemlins/mad.gif
Might be Eco friendly but not other boat friendly /forums/images/graemlins/shocked.gif

What type of motorcat was it?

I saw a monohull create a tremendous wash the other day - it was an esso supertanker. As a result I think all monos should be banned from the rivers due to the damage they do to the riverbanks.

Yes I have seen some cats cause terrible wash just like many monos.(usually planing cat at low speed or inefficient commercial cats - heavy built, wide beamed, deep drafted with big engines primarily used for a stable platform)

On other hand - some efficient cat designs cause virtually no wash due to lightweight and vastly superior hull efficiency.

I've bought one of these http://www.motorcats.com motorcats and the wash is minimal. I'm sensitive to excessive wash, not just as a former raggie, but because my garden runs down to a river and the bank erodes if you look at it hard. Vast numbers of small monohulls zip up and down in breach of speed limits leaving enormous wash in their wake. The motorcat barely leaves a ripple.

Sorry cant tell you what it was
noticed it and looked inquisitevly then got the shock wave
IT WAS NOT NICE
and it was only going slowly
and....no no other traffic could have caused it

 

[hobiecat]

If it was going slowly and caused excessive wash it could have been a planing cat. Generally, planing cats are much less efficent than monos at low speed - hence excessive wash. Ask world champ Steve Curtis how they go at high speeds.

Does that mean that when people drone on about how little wake motorcats make they are comparing apples and oranges - A displacement cat against a planing mono hull?

The truth always comes out eventually.....

 

[totopalm]

Much more xciting is the wake from the HSS Cat out of
Harwich to the Hook,don't get beam on to her wash when
she is at full chat!!

 

[hobiecat]

The narrow hulls of an efficient displacement cat with small engines are able of producing far less wash than any mono - barring perhaps something like a canoe.

If you want to stick with low wash monos why not design and build a cruising canoe?
