How long does the build take?

At a minimum, it is recommended to schedule 10 hours of build time. The remaining time should be spent on designing, modifying and testing. Follow the sample POA&M published on the phillyseaperch.org website.


  1. How can I obtain spare parts?

You may send a request through phillyseaperch.org web and check for availability. If parts are NOT available through excess inventory refer to page 22 for a list of parts and vendors.


  1. What if we don’t have a pool?

Contact the Independence Seaport Museum and schedule a practice session, local hotels, YMCAs or colleges. Many times they will allow you access for your testing. If all else fails, you can purchase a small above-ground pool or use a large plastic tub.


  1. Is it legal to stack two or more Jameco P/N 232022 props on the motor shafts used for propulsion?

A team can use as many props as they want and in any configuration. Teams may not add additional thrusters to the Sea Perch. A thruster is defined as a means of propulsion for the Sea Perch, normally but not limited to a motor and propeller assembly.
At the Regional Competition level, the rules were written to reflect that no more than three motors for propulsion can be used and the motors must be the ones supplied with the kit. Teams are free to choose their craft's method of propulsion, provided it meets the budget criteria established for the Challenge. They can use as many props as they want and in any configuration. Track systems that drive on the bottom of the pool are also acceptable as long as they stick to the three propulsion motor rule.


  1. Do we count additional ballast into our budget?

Since the flotation provided for the Sea Perch kit can be easily modified to adjust the buoyancy of the craft, there should be no need for additional ballast. Therefore, any additional ballast that the teams decide to purchase must be accounted for in their receipts. Rocks could be used for free though as long as they haven't been purchased.


  1. How many team members are permitted on a team?

There is no limit. Refer to the rules and guidelines regarding the number of team members permitted to actually compete in each of the categories during the competition. Spectators and excess team members are welcome.
