    The steering consists of a Imco cylinder and a Capilano helm. It steers like a dream at slow speeds, but when you are running it hard (90 plus)it gets a little tough to turn. The rigging on the boat came out real nice. It comes across clean and well sorted.

    As you can see in the last 2 pictures, this boat has some nice interior space. Also show are the jack plate and trim switches located on the steering column with blinker type switches. I like that feature very much. When you are running hard it makes it way easier to operate those functions.

    I wonder what kind of speeds these small tunnel boats will do with the new 400XS ?

    It's supposed to be unveiled at the Miami boat show.

    Wow! 400 in one motor. I remember when Crystler (sp?) came out with the 105. I may have been 10 years old at the time but that was a huge monolith of a motor when most boats with big motors had a Starflight 60 V4. That was before the Merc inline 6's.

    XXXXXXXXXXXXXXXX

    What speed can an old style hull such as an 18' bubble deck do realistically before going to hell in a hand basket handling wise? 60? 65?

    Thanks for the link Jim - very informative. It confirms what I thought - mid 60's is about it. Now I have to figgure out how much I love the fast boat vs putting that money into the Dyne. Hopefully I can do both but am not sure.

    Good morning.
    Having been exceptionally fortunate to drive the Mighty BanoDyne on its home lake,Mark provided some information about the top speed of his '73 Bubble Deck 18'. Around 67 MPH it would get squirrelly. After reading the previous posts on this thread, I am not sure if Mark altered the depth of the motor or not. I believe that he was using a 21 inch pitch stainless prop.
