    Eric has told me a bit about this boat and it will be VERY interesting, For those that dont know, Eric is one of the dudes that puts the Scott boats together and is a avid race follower. :wink:

    Yes but thats just the problem...........its all hearsay, I know someone that has radar checked a few and what is said and what is real is a Looooonnng way out.....So it would be nice to hear some honest figures as it would help people getting into the sport and make it less daunting.........

    nz1 told me so have faith in the info, fritz and I got passed enough in b class to know that b class is now very serious these days, too serious!!
    Of course a good wheel man/nav is worth 200hp in the skinny, which is what it should be all about

    If I was starting out racing I'd concentrate on getting a boat that was Very reliable & handled well rather than one that was Very fast so I could finish events & get the racing experience, as you got more experience you'd get quicker, once your at that point I'd then look at making the boat go faster.

    Also I'd want the boat to be good off the start line as a lot of time seems to be lost there by some teams.

    Here is what I have been told and I think this makes sense,

    D class 70mph
    C class 80mph
    B class 90mph
    A and U 100+

    All those speeds are around 20% slower than Linsay Hays official NZ speed records in each class, which were set in the mid 90s . Given advances in hull design and engine tecnology perhaps they are alittle on the conservative side.?.

    The speeds that Mike has posted are average speeds for the classes, there are faster and slower boats in all the classes.

    Thats right, Its just to show a good starting target and anyway its not always the faster boat that wins most of it comes down to the driver and having a package that holds together.

    This an interesting one. We build Race boats and I have done alot of testing with Neil Ross and he reakons he passes alot of "110MPH" boats doing 95 so there is a lot of BS in this sport for sure, I do know that Neils current boat does a flat water speed of up to 105 MPH running 700HP 458 small block (A class)but probably averages high 90's and Dan Anderson does about 92-95 running 630HP in B class.
    But its not all about staight line speed, the boat has to corner fast and this is where Neil and other guys in our hulls seem to gain time
