Andrew have never seen a single engine noosa cat but would be interested in seeing one if you have a photo, still trying to work out how to send photo to you.

no it doesn't have counter rotating props I heard that you can't have counter rotating on any thing less than 120 hp

Gday mate, we are into cats having had 5 in the family in the last 6 years. Dad has bought a 5.2 noosa cat lately and has had the same problems you are having. He has put foils on it which has helped and fitted hydraulic steering. They are most defiently not a fast hull and recommend a max speed of 20 odd knots if the seas are up a bit. Do you ever fish the sunshine coast. I would be willing to have a run in it with you and offer some suggestions. There is an art to driving a cat but once you suss them out there is no going back.

I agree with perko, some foils and some fine trimming will sort out the porpoising.

When I first got my small cat I took it out in the mool bay and stuffed around with it for yonks. flat chat, trim both motors up, then trim one up only, just to get used to its charactoristics. Turn the thing hard ( not too fast first up) then use the trim to rebalance the boat. It become second nature after a while, then I still stuff up. They seem to be very sensitive with the trim settings

Then tryed the backing down, not the best thing to do in a little cat, but again found the limits.

On a quiet day I then stuffed around trying to park the thing against the wharf, that was fun for all who watched. Even spent some time driving on and off the trailer.

They are a lot different to handle (used to a bigger monohull). I believe they have the handling characteristics of two besser bricks, but still love the challenge.

Dont know about the side to side stuff, uless you are talking about one side digging into the swell. If thats the case dont try and get into the situation, either back off beforehand or turn into the hull digging in. Oh and change nappy.

here is the web address www.noosacat.com.au

the 18 foot centre console can be optioned either in single or dual engine configuration. but the single engine boat with a 90hp two stroke can do over 31knots flat stick and cruise comfortably at 23knots. reasonable retail price as well

g'day tony thanks for the input it does have hydraulic steering it did have the foils on but i removed them and it seems to perform better with out them ,next time out i'll play around with the trim ,i'm convinced that it's an exelent boat and i think you are right about there being an art to driving one so i will keep trying . by the way i'm up at hervey bay but thanks for the offer stokey
