It depends on what you are racing. The typical IMPBA course is 330' long with 35' radius turns. Electrics run a smaller course as with race sites that have a smaller pond to run in.

The eight scale club I belong to's rulebook lists the following:
1. The standard race course shall be oval in shape, have two parallel straightaways, and be a minimum of sixty feet from the closest shore
2. Course dimensions must be turns 60 to 120 feet in diameter and straightaways 275 to 400 feet in length
3. The starting line shall be located near the middle of the straightaway nearest to the pit area
As you can see, race courses can have quite a variance in sizes. My particular club is an APBA sanctioned group. I don't know what NAMBA has for requirements. This is also for a scale hydro club. I don't know what class Ron was listing. He'll have to tell you that.

I found it in my rulebook. Here's the numbers that the IMPBA gives.
1/4 mile- 283' straights, 15' radius.
1/3 mile- 330' straights, 35' radius.
1/5 mile- (electric) 170' straights, 30' radius.
Hydrojunkies numbers fall into the 1/3 mile catagory. The IMPBA hads tolerances built into their measurements also. SAW runs are tighter with only .005 (0.6"!) feet tolerance!
