Volume 7 - Inspection Instructions

Inspection at The 2023 APBA Stock, Modified & Junior Summer Nationals in Wakefield MI

by Chief Inspector Kurt Romberg

If you plan on attending the summer nationals at Wakefield MI this year you can expect much of the same inspection procedures that you have seen for the past few years. All boats are required to have 2023 Nationals safety inspections before testing or competition. We will be doing safety inspections and motor sealing starting Sunday morning, 7/30/2023, at 10:00 am and going all day until somewhere around 5:00 pm. Then again on Monday, 7/31/2023, from 8:00 am until 5:00 pm (times may change without notice). These time slots are specifically devoted to completing these safety inspections and sealing motors. After inspection closes on Monday, a competitor will need a written excuse from the Chief Referee to get a safety inspection and can expect to volunteer for additional flights working in inspection to help carry the extra load.

The safety inspection process will be looking at all the things that we normally look at. See the list below. Plan on bringing your equipment to the inspection area where we can perform the safety inspection and seal the motor. Don’t forget to bring your life jacket, helmet, and Kevlar’s. Also check your kill switch lanyard. Make sure it releases prior to reaching within 12” of the transom. If you run the coiled plastic lanyard, check the coils for small cracks that tend to develop over time. We will be checking these and if yours is cracked we may ask you to replace it prior to getting a sticker.

Remember that helmets certified with a Snell 2010 sticker are no longer legal. A Snell 2015, or newer sticker must be located inside the helmet, under the padding.

There will be no pitting inside inspection. We need all of our space for prop swaps in the Junior classes and in 300SS.
