Hi I can buy a Ace Cat 550 For R 70 000 how is the handling of the 550 compared to the 555

The Difference between a 555 ACE CAT and a 550 ACE Cat is the 550's bow roller is not present.

There has only ever been a 550DV but not a CAT.

Hi Seadoc.  Thank you for the long explanation.   With our XL 115hp Yammies with 3 x 19P props at 4000 rpm we would get about 23 knots.  We could push the throttles some more but always felt that would be pushing the motors too hard.  Not knowing what I am learning now from you guys I realise we should have established what was going on.  So I think we might have been able to get 25 knots or so at 4500 rpm maybe a little faster.  But hardly reach 5000 rpm which are those motors maximum torque.  Thier WOT was 5500 rpm, which we would never have even got near.  So yes I believe those motors were lagging and there was about 24% slippage taking place. 

What would have happened if those props were 4 blade and slippage was reduced to say 10%?  Should we have been running with 17P on those motors?

Well thats all in the past.  Now looking at lengthening the shafts on our Suzuki's.  Going to cost around R27K.  I think it is a whole bottom unit and not just spacers.  Perhaps we can sell the old units and shafts as spares.

I have a worksheet to calculate theoretical speed through the water which I attach.  At this moment I believe we are looking at too many variables.  Motor height, prop pitch and 4 blade SS.  I think we need to get our motor height correct before any prop attributes can be measured.

 

Howzit Skippy,

Whats happening with Tail-Time and the Zuks?

Here is a bit of a Nostalgic ACE Craft Story .

On Gumtree, there is a 18,6 Ace Craft for sale with 2x90hp Yamaha's.
http://johannesburg.gumtree.co.za/c-Boats-Watercraft-motorboats-jet-skis-18-Foot-Deepsea-Boat-with-2x85-Yamaha-motors-W0QQAdIdZ387923997

Not really in Prime Condition but a bargain none the less for a project boat , The Boats Name is " Bonito" and belonged to a Gentleman named Piet Joubert many moons ago.

Here is a bit of SA Angling fishing lore..

This Boat won the 1994 Billfish Competition and what makes it interresting is that the competition was won when , Piets crew did not pitch and he decided to Surf launch and go fishing SOLO.

Somewhere around Mid Day , after setting outriggers , rod spread north of Mabibi, he hooked into a Marlin, and all hell broke loose on that boat. The marlin Stayed Hooked , Piet Cut his foot somewhere on the deck. After a Long fight the Marlin was boated 2 hrs after Lines Up , and just made it back before dark onto the Beach. During his return back he was lead in by Piet van Dyk on his Boat "Yelowfin" also a ACE Craft, with great exitement and applause on the beach being the last boat in.

This Story is also told and compared to Ernest Hemmingways "The old man and the sea" in the Sept/Oct 2010 issue of Skiboat magazine.

Nice friends!

Maybe they were all in hospital with back injuries? :SSS

Some of them are with the "Spirit in the Sky" chasing whatever there is to catch . Piet van Dyk on the other hand is playing Golf everyday on Leopard Creek and in the evenings he watches all these youtube clips on Sealine of these new (Buka Mina) Cats roll in the shallow water and their crew swimming back for dear life and then laughs himself to sleep.
