Devils Lake – How It Works

A straightaway time trial is a unique event.  If you haven’t watched or participated before, Here is some information on how it works.

  1. Who can run?

At Devils Lake, any boat in an APBA recognized class, with an APBA member driver can run – up 175 mph.  This can range from the Modified Outboard hydro above to…

2. What is the race course?

Boats run either a one kilometer or a one quarter mile straightaway course.  There is a run-in, and run-out area at each end of the course.  See this map for more information.

3. How are speeds calculated?

APBA Regions 10 and 11 utilize optical scanners on turntables to track boats as they enter and leave the race course.  The area between the entry to the course and the exit from the course is called the “traps”.  The traps are surveyed to be one kilometer and one quarter mile.  The scanners are located on a survey mark, and are aligned with another survey mark on the far shore. When the scanner operator has tracked the boat to the trap entrance (90 degrees to the course line), a switch is triggered that starts an electronic clock.  The scene repeats at the next scanner location, only this time the switch stops the clock.  The Chief Timer then calculates the speed based upon the time and distance.

4. I’m a racer – how do I play?

You enter like any other race.  Register on-line, send an entry form or email or phone call to the Chief Scorer listed on the sanction.  You can also contact the Race Director or Assistant Referee.  Entries are $175 for a National record run per distance (three sets of passes), and $60 for a Region record run per distance (one set, must be a member of a Region 10 club in good standing) – unless you register before on-site registration; then you pay only $150 and $50 respectively.

At driver’s meeting each day (7 AM SHARP!), racers draw for their place in line.  Since the event begins as early as 8:30 AM, some consideration is given to running quieter boats early on.  Racers declare if they are using a kilo or quarter mile entry. Once the event begins, and we move through the list, racers can choose to pass, take one set of runs, two sets of runs, or all three runs.  A set of runs consists of a complete transit of the traps in both directions. Times taken are the fastest of two consecutive runs.  Once the list has been completed, a second round begins, then a third.

5. How many sets of three passes can I buy?

As many as you like, time on the water permitting.  One of the exciting aspects of the event is when two or more racers are attempting the same record.  As they trade the record back and forth, often additional sets of passes are purchased.  Another element of drama occurs when a racer is very close to a record –  after three sets of passes, they may be close enough that an additional set up  tweak may get them there, so they buy another set.

6. Can I run both days?

Absolutely.  Or just run one.  As with any boat race, wind and water conditions can change without notice.

7. Do I have to use a special “kilo boat”?

Not necessarily.  Many records are held by regular competition boats…

8.  Can I camp in the pits like at other races?

Sorry – NO.  The State Park used for the pit area does not allow overnight camping.  CORA has a waiver to allow a couple RVs in the pits overnight for security of the racing equipment.  There are a number of camping and lodging options, some extremely close to the pit area.
