As I mentioned on another thread I really can't see the P1 stance on this speed thing, when you look at all the fuss P1 made about SuperSport breaking out over 85mph in 38-40' boats and how dangerous they considered it to be bla bla bla ... yet they are prepared to allow the racing of a light 26' boat at 75ish mph only 12% less speed in a boat volume wise is massively smaller, seems completely bonkers logic to me
Our 970kg 24' race RIB with a 280EFI on the back got well into the 80's offshore in race trim without pushing too hard and managed 91.5mph on Coniston with a setback bracket and a lifter, so I would think that the Cougar should see over 80mph when run in and set up with the right prop and the engine at the correct height.

With regard to the P1 speed limits - you have to know the history. The UIM set the speed limits for safety reasons which are related to speed in open cockpit boats only and not to speed related to size etc. Crashing any open cockpit boat at over 80mph is going to make a dent in its occupants - the likelihood of that boat crashing due to its design and inherent stability is another story altogether.

honda

we had 95 with a 280 that was in full race trim , and 83 with a 200xs ,so 79 with a 300 is a bit crap.

Yes they were low 60's in the very early 80's but then the 1980 Merc probably didn't have 150hp at the prop where as by mid 80's I think the speeds had crept up a bit as the good ole Merc gained a few hussies at the prop

Ok thanks Cookee although that also sounds a bit well silly ... like who's going to fall out of their boat in a rough offshore event easier at 85mph a guy in a little 21'er or a guy in a whopping big 40'er ... erm let me guess

PS and ye banana rubbery thing did go like the clappers, think you'll need a few more orses to get the 34' to 90.15mph but it would be great if you did

That seems very low.

The P23 of mid 1970's ran 73mph with a pair of straight six 150's, Steve 'averaged' 65mph over the 230 mile London Calais London of 1975.

I'd be very surprised if the 25 was such a step backwards top speed wise (when set up right), they wouldn't have sold any.

The 150 of 1985 (brown/gold band), was the very same engine as the 175 of pre 1985 (blue band), Just prop rated instead of Crank rated. The only increases came with the 150 XR2, and XR2 Sport etc from 1986, where they went from 162hp, up to 192hp in the final guise.

I understand that a correctly set up 25 with 192hp XR2 Sports would run close to 80.

I'm sure Eric could give some fine detail.

Hi John

Our 25 Phantom ran 70 -73 mph with a pair of 1983 150 hps ( prop hp )
then with the 1986 162 hp XR2 ( prop hp ) with the oil injection and spark advance box and all the std XR2 bits it would run 72-75 mph .
and the best boat by a long way in the rough ?? , would run 50- 60 mph even when very rough .

Hi RobMac 3,

have you got that link to the clip of your record breaking?...I was talking to Dobby today at CPR and he wanted to see it...I told him it was the best balanced and trimmed boat I had ever seen in all my three years of racin'

Happy New Year!- sadly no Dubai next week eh? Gringo is probably padding his walls in his red and white shrine as we speak (or his camper as I am sure he is in it somewhere away in the wilderness). I reckon he had his own style of advent calendar: counting down the days and now the postponement is likely to send him over the edge poor fellow... I'll send him a little red cross parcel.

We're waiting to see if we got the job on a twin 525 version of the 34 - should get us a tad over 91mph

There has to be something wrong there Cookee, our estimate with the Ring 34 is in much the same area with two 6.2L small blocks.

I don't want to put a dampner on all this excitement about the Cougar25 running at 79MPH (probably a lot less with the de-tuned engine) but as an ex organiser of races the thought of even 10 one design and powered race boats closing on the first turn buoy all together, flat out, fills me with horror especially as they are so well known for being "twitchy" on turns.

No one wants another Dover incident but I guess nothing is going to stop guys wanting to do this.

It's so much easier in Marathon racing with the first turn buoy 90 miles away. Gives the boats time to spread out unlike circuit racing. Just my humble opinion.

Maybe my 60+mph is clouded a bit by time I was kinda going on the fact some of the 25's only seemed 6-8mph quicker than the ole Ring that did 58mph at it's fastest and although I spoke a few times to Ian Bernie in his Canford Cliffs driveway I really can't recall what he said about speeds etc

(and of course the 25's that did not seem that much quicker may have had issues)

Anyhow what was for sure is we always ate the wake of the leading 25's, and pretty dam quick at that, I would of loved one on my Xmas wish list but at 20ish the cash was not available to buy it or run it

PS ... Mrs Smillie I probably dribbled over your Phantom 25 on many occasions sorry about the mess

You must have missed the sarcastic smiley on the end then ..........

So what is your estimated top speed with the Ring 34 with 6.2l small blocks?

Nah, I saw it. Just wanted a bit of fun on a boring cold morning.

Estimated max speed? more than my life is worth to tell you.
