Not arguing legality by any means- just a question.Not legal in IMPBA heat racing or record trials but is legal for offshore class.

I can tell you that more time was spent on this definition - what's a mono - than any other part of the rule book when we put it all on paper and did the first printed rule book.Andy,
I have tried steps in various spots on my mono hulls over the years and run them in races as hydros. I got 6th or 7th place at the Indy Unlimited one year with a stepped mono with over 100 boats all in the same class. Most all hydros. Just thought it would be fun. Point is I like to experiment and try new things to keep modeling interesting. I have found the difference in steps on a mono vs no steps to be negligible for full out racing because if a mono is trimmed out correctly only the rear inch or two is touching the water. I did run steps like the picture in this thread on a Seaducer as a matter of fact and it did not change a thing in cornering. All that said to say....... The rules have to be written to cover many scenarios and this step for example while looking harmless, if it was legal: someone would make it larger and larger until the boat became a full blown hydro. The only way to keep a mono class different from a hydro class is to eliminate steps.

Darin, is the break only on the one side? Looks that way from the picture.
John, again I tried to cover steps and other planing issues in my High Speed High Speed Hull Design Series. Steps probably help boats with a lower power to weight ratio than we have with models. A lot of interesting things have been tried. If you want to run a legal stepped mono, you can move the tabs a little up from the bottom of the hull to create a step. Below is a picture showing a crackerbox that is using the tabs as part of the planing surface.Andy,
