When does the season start?
Practices are set to begin the week of September 12, 2022. Senior groups may return Tuesday, September 6, after Labor Day which will be communicated by the coaches.

When will we know if our child made the team? 
You will be contacted no later than Friday, August 12th at 8:00 p.m. with either an invite to join the team, a waitlist number should spots become available, or suggestions for next steps for your child. The last tryout is Monday, August 8, 2022.

How many spots are available this season?
Approximately 100 spots are available. Most open spots are in the 10 &under age groups.

If we are waitlisted, when will we know if we have a spot?
City of Mason Manta Ray staff will contact waitlist enrollments through Friday, August 26.  After that date, we recommend looking into opportunities to improve swim skills in the Mason Swim Academy and to reach out to local teams until tryouts the following year.

What does the competition year look like?
The 2022-2023 season will run September 2022 through August 2023. Short course season is from September 2022 to March 2023. There will be a 2-week break in the spring and the long course season is from April 2023 – July 2023. Qualified Manta Ray swimmers may extend into August 2023.

Where are swim meets?
In previous years, Manta Rays have competed in meets at Silverlake Rec Center (Kentucky), Keating Natatorium, Miami University (Oxford), in Dayton at either the WTRC pool or Dayton Raiders pool, Cincinnati Country Day, and have a couple travel meets a year in either Indianapolis, Elkhart, Lexington, and Greensboro during long course season. The City of Mason hosts in-season meets as well as possibly host short course regional championships in February. With the addition of the Mason Municipal Aquatic Center 50-meter facility this is anticipated to expand into hosting more short course meets as well as long course meets.

What is the practice schedule?
The practice schedule will be posted as soon as possible.  A tentative practice schedule is available on Team Unify.

Do you need to be a member of the Mason Community Center to swim for the Manta Rays?
Yes. Each City of Mason Manta Ray swimmer must maintain an active Community Center membership for the duration of the competition year. You will need an active membership to register for the team should your athlete be offered a spot for the upcoming season.  All Manta Rays participants must have a Mason Community Center Premier membership for the 2022-2023 competition year.

Does the team require families to complete service hours?
Yes. Each family is required to complete a minimum of 30 hours per family over the course of the competition year. If you have multiple swimmers on the team, it is a total of 30 hours, not 30 hours per swimmer. Service hours can be completed by volunteering at meets, in the form of donations for meets or practice/group activities, as an USA official working the meets (training required), or you may choose to pay a fee to cover your hour requirement prior to the start of the season.

How is the Mason Manta Rays Team Unify website used?
Masonswimming.org is our team website used primarily for communication, meet entries, and meet fees.

How is registration completed?
