Woobs~
Another project hull that you might wish to consider for your Retro Gentleman's Racer Speedster is the Chris ~Craft Lancer 23' .
There are several size length C~C Lancer hulls.
These boats came in straight Inboard, Inboard V-Drive, & Inboard/Outdtive power configurations.
There is a spectacular retro Mahogany deck & transom Gentleman's Racer/Speedster conversion project that was posted several years back on that other Donzi website.
The fellow who did this build-up did a spectacular conversion job.
I believe the C~C Lancer was possibly designed by Jim Wynne who also designed for Donzi .
They are very slick fast early Deep V designs.
Chris~Craft built very large numbers of these various Lancer models .
Often there are very cheap project Lancer hulls to be found everywhere .
At one time there were at leat a half dozen of these boats in, and around the Ocean City NJ & Atlantic City NJ area.
My Father & I always liked the way a Chris~Craft Lancer would plane & ride in rough water at high speeds.
In the last few years, or so, these boats have developed a cult following among early fiberglass boat restorers & collectors today because of their style & great fast ride quality.
Dad & I should never have sold that boat !
