Scary Cat

[insideout]

while i was at the santuary cove boat show, i saw a cat that was built in wa,and the guys on board clamed that this breed of cat actually banked in like a monohull in a turn..Iknow that mine does the opposite, and was a bit suprised to see the video footage of this cat loaded evenly with crew actually leaned into a turn!!Not only that, it turned at speed to within 3 lenghts of itself!! Two things mine does not. Especially the turn at speed!! It does not like it much. It is interesting that cat hulls can be so different to give such different preformances. I tried to geta look at the hull config, but could not.This footage has sparked my interest in designs that can help a cats ride.

Insideout, I wonder if the manufacturer you mention had a quick flick and add some herbs to the outside motor, which would do the same, dunno about the 3 lenghts bits. LOL. Don't quote me i'm still learning to drive mine.
The law of physic is pretty hard to overcome once you are set within a parametre.

Cats leaning out on a turn...
What do you think a car does when you go around a corner fast.
Unless you want to tow tubes who cares how a cat turns - the only turn I do is to come home from the shelf

Well i have to thank all of you guy's, i started this thread to gain some help for a friend. WOW i never expected to get so much help. It certainly appears that new owners and drivers of cats all brands and sizes just need the hours behind the wheel in all types of sea conditions and a little encouragement from other owners that the cat pleasures will soon come.
Thanks to you all again MARK.

G'day

The dominators will lean in on a turn, due to having a hull similar to having a tunnel carvel out of a mono.

Regards to a cat turning within 3 lengts of itself ?? On the 7M coastal Cat we had it at full noise and the put her into a full lock turn. Scary at first but totally safe, handled like on rails.

I should clarify, " at speed" what i mean is about 15 knts, not full tilt wot. Lemn5 obvoiusly you dont have much to dodge on the trip out - home, Whales, shagging turtles, longstrings of crabpots,ect.

I've been watching this thread with interest and I'm glad I own a 6m alloy jaycat.
great boat with good speed and economy, easy to drive in a following sea, drives great in most conditions, just like a limo, quiet and smooth.

Only a fool would try to hard turn a fast cat above 25knots. Good turns are usually safe and smooth with a common sense driver. Not all cats are the same and most cats are influenced by driver experience and load. Most cats and mono hulls for that matter don't drive as good in a heavy following sea.

I think that kevlacat owners should not be discouraged by some comments posted as I have been in more scary rides in mono hulls than cats. I previously owned a twin turbo engined 28ft shaft drive bertram.... the best reputation as a sea boat.... was not real happy in a big following sea but was still one of the best and safest mono's made.

My cat is great...6mt. twin 140 4s' plate alloy by Offshore Marine Master.

Very nice cat indeed Big G!! Just wondering how you would compare an aluminium cat to a fibreglass cat for ride quality?? Is the fibreglass a bit quieter as in doesnt shudder and thump( even tho cats rarely thump) as much when they touchdown or is the ally up there with the glass? Ive been in lots of different glass cats( sharkcats, kevlacats, coastalcats etc.) but never an aluminium cat.. Always been very curious, once again thumbs up for your rig it looks great!

Dean,
I guess when we think alluminium we think tinny and your right that would be noisy...... but 4mm alloy plate at the top of the tunnel then 50mm of closed cell foam sandwiched between another 4mm plate floor, covered by good quality marine carpet makes for a sound proof barrier between you and those big waves.
The full range of boats made by OMM all have positive flotation using closed cell foam blocks...... it has also been used under the floor of the queen size bed which covers the entire front section where most tunnel thumping might take place.

This cat is very quiet and with the sealed cabin door and 2/140hp 4 strokes giving around 20knots at 3900rpm you can imagine how comfortable and quiet cruising is......like I said it reminds me of driving a limo.

[Big G]

Dean,
if you look at the photo of my boat under construction you can see the frames above the tunnel top... that is where the closed cell foam planking goes..... then the floor... then the carpet.
also the queensize bed up the front has carpet then appolstery matress.
OMM also use this foam in all their inbuilt ice boxes.... the best insulation you will ever see.

Looks good Big G.. Youv definetly got yourself a solid investment there. Id love to go for a run in one of em.. OMM build nice boats mate and your boat is a fine example

What area are you from?

[lutjanus]

Lots of good advice in here.I have owned 3 Kevlacats,as well as 3 other brands over the years and done 10000hrs in em.Word of warning though -dont drive them to hard down sea as some are advising.Back off if worried.I buried a KC once through this.NOT GOOD FEELING>

[jeffo]

interesting thread!! having fished on a few different KC's of a few different sizes i can tell you all of them do the little "cat walk" in a following sea....but who would have it any other way. Once ya get used to it i reckon its great fun- they seam to double in speed down the face!! A mate fished the cairns heavy tackle season last year in his 6.5KC and encountered some horrific conditions (30 knots plus) and the boat handled like a trooper. Have confidence they wont fall over and like others have said put the throttle down that little bit more to get them rightout of the water.

mate theres a 6.2mt Kevlacat at John Crawford Marine.............. wouldnt i love to drive out with her.................only a paltry $ 68,500.00.............. twin 115 4 banger yammies on the back
