Aha!  Slowly figuring this attachment thing out.  So we got to the garage and puttered.  Gave the boy some lay up tips and tricks.  Built the sides for the sponsons.

Two ideas have occured to me regarding a modified Minimax design. One of them is to make a seperate center section with the sides being built as sealed box form which are attached with bolts and are therefore easily removeable. This 'take down' design would be easy to transport and also be easy to modify or experiment with. The sealed side pods would give lots of bouyancy to the design and longer sides could pickle fork the front and allow the engine to be set in at the stern.
The other is to fit a MM with hydrofoils to lift the hull completely free of the water.  Last winter I was tempted to try our unfinished Minimax as a toboggan - sadly the snow here did not last long enough to do the experiment.

Oh yes, I'm watching Smitty! Got a little sidetracked from boats though, as some other interesting stuff turned up too. I like the strip planked idea, a nice way to achieve compound curves and surfaces. Somewhere in the workshop I have some old wooden blinds, the slats are solid hardwood about two millimeters thick and thirty five wide, and I have kept them for a diagonal plank experiment, so this idea for decking the sponsons appeals to me. I think this TunnelMax is a great project, maybe the start of something new in construction techniques - a good bit of lateral thinking! Can't wait to see the finished product.

Did you find your son a motor for the sea flea? If you still need one , call me. I have about 8 ! I'm sure we can select a suitable  unit for less than $500. Best regards. Wain in

Thanks guys.  I have to set down my tools for awhile.  I had surgery last week and can't lift anything for awhile which is frustrating.  I might get the young lad to take on a little more- we shall see.  I have the boat flipped over and I am going to work on the chines next.  My son planed a really nice roll off angle to the rails.  I am thinking I may use a composite build up of carbon, S glass and Divinicell for the chines and pontoon hull to keep weight down.  I will definitely post pictures as we progress.
General / Racing slide show

This might interest a few of you, a slide show of still photos taken at a U.S. Title Series championship race in DePue, Illinois this summer. 

The USTS is a major sanctioning body for "PRO" (Professional Racing Outboard) racing, the others being the American Power Boat Association or APBA (which also sanctions races for other kinds of outboards, plus Inboards and other craft), and the Union of International Motorboating (more properly rendered in French) or UIM, which runs PRO-style racing in Europe.

PRO outboarding (rather mis-named because there is little money to be made doing it) designates outboard hydroplane and runabout hulls powered by state-of-the-art 2-stroke engines burning methanol, and open to almost any kind of modification by the owner short of supercharging, non-liquid fuels, or exceeding the class displacement limits.  The classes are 125cc, 175cc, 250cc, 350cc, 500cc, 700cc, and 1100cc, for either hydros or runabouts. This is a real gear-head's sport, as differentiated from Stock Outboard racing (gasoline for fuel, no modifications to the engines) which is more of a just-a-driver sport (although owners sometimes build their own boats, usually from plans) (If you watch the show you will see an occasional photo of small hydros with cowlings on the engines that say Evinrude or Johnson;  these are Stock machines used in a couple of PRO "starter" classes).

The first part of the show, which you can skip, is dedicated to long-time participants in PRO racing who passed away this year (NOT on a racecourse).  The next part is dedicated to photos taken in the pits, and will show you the equipment, surrounded by a lot of people you don't know.  But take note of what a family-friendly pasttime this is.  Many of these people have known each other for years or decades, and any race is almost more about hanging out with like-minded friends-for-life than it is with the on the water competition. For serious competition that is rather expensive and sometimes somewhat dangerous, being engaged in by a variety of personality types, there are surprisingly few instances of serious or lasting rancor.

Take a look. If this strikes your fancy you can find more info, including schedules of races near your area, by going to the USTS or APBA websites.

Thomson, the words "modifications" or "custom" are much too weak to cover what you are doing!  It strikes me that a possible name for the boat would be "Transformer," like the kids' toys the turn from one thing into something entirely different. And if that weren't enough, you bring from the outside a building method utterly unknown to either hydros or fleas, so far as I know.  Ken, are you watching this?!!

You got it!    And then tweak from there with the trim!
