TNT As a Racing Runabout?

Post by ponyboy03_ »

I've been looking at building one of these for a while now, and I really like the look, the size and the weight of it. I have also seen the "Class CD Racing Runabout", but it seems too heavy and needs a bigger engine. So, can I use the TNT for racing and does it need to be modified first? I would be using a modified 1972 merc 200 with 30 to 40hp.

Thanks in advance!

I suppose that would depend on if there is a racing class the TNT fits into? Don't think we have anyone on the forum that actively races a Glen-L boat?

We had a guy that raced a Cracker Box. It didn't meet the Tech-Spec. They would let him race. He could not be the winner.

Yah I figured as much but to define racing, I mean racing other boats out on the lake outside of a posed competition. I guess what i really want to know is if the TNT could take speeds up to 120kph or not.

Thats just under 75 mph. It would take signifcant changes to be able to handle that speed. At that point you would be better off getting a plan set for a boat that is designed for said speed. I helped build a couple of cracker boxes that were actually raced, thier design and construction was so far removed from the glen l cracker box, it might as well been a different boat.

What would happen if you tried to bring the TNT up to speeds like this?

At best it would be extremely unstable. My guess it
Would suffer structural faliure. How bad is the question.


Also having been around the world of small boat racing, you will also be running a very expensive custom made prop.

I would recomend you look up the apba.

Thank you thats valuable info. Ironically, my race prop is being cased at the foundry today in Norway by Winrace propellers. They said its going to cost 700 bucks all and done to have it in my hands :x . They work really fast actually, great company.
