Can be adapted to the Mini Tunnel
The original Dillon Mini Tunnel was built in 2006 and was my first attempt at tunnel boat design. I had good luck with the Mini, but it was clear that there was room for improvement both in design and construction. In 2009 I incorporated those improvements into a new design which became the very successful Dillon Pro Tunnel.
Since the introduction of the Pro Tunnel, sales of Mini Tunnel plans have dropped considerably.
In the spring of 2011 I completed a rebuild of the original Mini Tunnel. The main goal was to deepen the tunnel up front, allowing it to gulp more air for more lift, and to raise its shovel-nosed bow a little higher off the water so that it was less likely to dive into a wave.
The results were promising, and so it became my intension to completely redesign the Mini Tunnel. Now that has been done.
The Redesinged Mini Tunnel is a few inches shorter than the original, has a deeper tunnel forward, and has the pickle-fork bow that one expects of a tunnel boat.
I am suggesting this boat as a good choice for a younster (or other light-weight driver) using a smaller motor, say 15-20 hp. On the other hand, the Mini Tunnel should still be able to handle the 30/35 hp OMC motors used in GT Pro racing, though the Pro Tunnel is probably better suited for that purpose.
The Redesigned Mini Tunnel may also be suitable for Junior Class racing in Australia, which uses 15 hp motors for their top Junior division.
This boat should NOT be used with any motor exceeding 120 lbs.
