NAMBA Surveyed Race Sites

[What up Dog]

It would be interesting to know how many NAMBA sanction ponds are legal and a surveyed courses. I'm not sure how many Race sites there are out there in NAMBA. But how many can say that they are legal to set records. This is the Question? What Survey documentation do you have to show you are a legal Course?

Our corse up here in the great white north ( Edmonton Alberta ) may not be surveyed but is set-up using steel pins on the shoreline and a rope marked out and strung across the pond.

There are no IMPBA Members listed in the west. Seems kind of weird to me.

Dist 8 NAMBA can set a record course on 2 of our lakes. Waughop and Twin Lakes. Waughop is real tight so we usually only just throw them in by eye. Except for the 2 lap event that we hold there at least once a year. Tons of room in Twin Lakes. We have held 2 national events there. We have 2 pivots buoys that are set in the center of turn. Then use a steel leader to measure out the radius. We use bobbers to float the steel line. Use the same for the straight away. Usually takes about an hour to do. The pivot bouys are large crap pots with a large concrete anchor. We push it in below the surface to keep the pivot from moving. Works real nice. We are not allow to do anything permanent at both sites. For the national event, I do something a little more permanent for the week. So we dont have to keep remeasuring with lost buoys.

Mike,

If you can not have anything permanent then you can not have a surveyed record course! Records can only be set on a surveyed course.

I don't see where it says that in the NAMBA rule book. If that's true, there are a lot of two lap records that aren't valid. There's a lot of information about the dimensions, but no specification about methods or tolerances. The CD is required to certify that the course meets the specifications.

One Mile - Six Lap Record Course
a. The course will be one mile in total length for all classes.
b. The course will be six laps for all classes.
c. The radii used when establishing this course will not exceed 50 feet or be less
than 15 feet.
d. Five buoys will be used to define the turn, except on 15 feet radii turns which
may use three buoys.
e. When optional straightaway buoys are used, a maximum of three buoys will
be used for each straightaway.

I have been CD for some of these events and have set the course personally. I verify that the course is set correctly. I also have verified the measuring leader we use. It needed some repair in the past from frayed wire. I redid the whole line and check all the measurement on it.

That's not true here is what the Rule book says,

A legal course for NAMBA Heat Racing and Oval Time Trial records must be either one in which each buoy is surveyed and placed in a fixed position, or one which is measured and has the straightaway marked by a solid fixture on each end. This fixture can either be on the water or on two sides of the lake so that a line can be drawn across to set the straightaway end positions. The radius will then be measured from these fixed straightaway end positions, and will apply to all turn buoys. The lines or devices that are used for measuring will be at the site during a race in the event that anyone should desire to verify the measurements or placement of a buoy.

 

[LohringMiller]

True, but again no methods or tolerances are specified. Our pond is so wide that markers can't be placed on both shores. That's also true on the pond Mike is talking about. It is straightforward to sight into the pond from a shore baseline. There are fancy ways and simple ways to do this. Most courses I have raced at use fixed center buoys to define the turn radius. The exact turn buoy position isn't as important as the radius. The fixed center buoys are either set on the water as Mike described or measured out from shore points as our club does. Without a tolerance on the allowed positions I don't see a need for a professional surveyor.

Again, if that's what is required, nearly all the heat racing records and most of the SAW and two lap records that weren't set at Legg Lake are suspect and should be disallowed. That's guaranteed to seriously irritate those of us who enjoy record setting. The Legg Lake record events aren't being run currently so where can records be set? There aren't millions of dollars involved after all.

Well I do know that Sunset park in Las Vegas is a Leagal Course. It's been surveyed.

 

[Mike Hughes]

Well then we might set some records during the nationals. But only heat racing ones.

Yes Mike that is correct. I do believe that there are 3 classes right now that has no records as of yet. That's what was told to me from Richard Romero
