Thanks mate. I've never seen a 20 in the flesh but they look like a pretty big boat compared to the 19.
ex twin turbo 19 ski race boat I want to repower with something a bit quieter

I agree Malcolm even though both mine are well over 25 years old they still turn heads. My young bloke would love a wake boat but I just cant bring myself to buy one. Is that a jet? It seems that most of the 19s over there are I havent seen one in Australia even though jets were popular in other hulls like the Hallet etc during the late 70s.
Daves right on handful to drive over 100 the tail seems to lift a lot.I was told
few years back that there was a mold for the 19 floating around downunder
Ive driven both vee drive and jet with big power and very fun boats to drive.

My understanding that the mold is over @Carrera boats these days Iam sure Stan and KevinStan from Crusader boats has a 19 mold ready to go if anyone wants one.

The blue boat has a very narrow center plate, does it have a 'delta pad bottom' (built with an insert in the mold) ? Why is the center plate fixed ? Down under, are you running a 'big gear ratio' and a '14 or 15 pitch prop' with the turbo/ big power ? Thanks .....
running the bigger overdrives (72% overdriven) reduces the effective torque at the prop . Out here in the southwest USA, many are running lower gears (29/32) and less slip with 16/17 pitch props . However, when the prop 'slip numbers improve', the torque reaction to the hull increases . I can see that with the narrow 'pad' on the blue boat, torque reaction VS prop slip would effect the control and have bad consequences . Reduce throttle slightly in a turn and that 16 pitch 'bites for a split second', and the boat would roll out to the right, hard . Most of the Spectra 19's I've seen have had no 'pad' or 'flat spot', nor have they had the center strakes lengthened towards the transom more . (to hold the tail up) I've found that with the 'jet style round bottom', the faster V-drives get up on the keel behind those center strakes, and they become unstable . Someone (down under) may have noticed that problem and modified the riding surface of the hulls available there . If possible, I suggest a 12" wide delta pad, with no more than 1 degree of rise to the rear . This would make the pad about 5' long and just wide enough to resist 'torque reaction' and still deep enough to keep most of the 'spray' off the bottom near the transom . Then you could make the center plate movable, and use it for more straight line speed and better breaking, going into the turns .
