Frequently Asked Questions
Is Sea Base Registration per-person?
No, Sea Base Registrations are made on a per-crew basis. The adventure is priced as a whole, and the cost does not change with fewer participants. Crew sizes are 4-6, 6-8, 10-12, and 18- 20 participants. We do not provide refunds for crews bringing fewer people than the maximum crew size.
Opportunities for individuals to attend Sea Base:
Scout Connections Page: review a listing of units who have open space in their Sea Base crews and connect to join them!
Can my crew be composed of individuals from two different units?
Yes, with the approval of each unit’s charter organization. Every participant must be a registered member of Scouting America, meet all other eligibility guidelines and meet minimum age requirements by their adventure start date.
Can my crew include both male and female individuals?
Yes, coed crews may attend. Refer to the Youth Protection guidelines for specific buddy-pair and leadership requirements per Scouting America. Contact your charter organization to ensure that you are following Scouting America’s Guide to Safe Scouting, Youth Protection, and Barriers to Abuse and your charter organization’s policies.
Do the maximum crew sizes include adult leaders?
Yes. Sea Base requires a minimum of two adult leaders age 21 or older to attend with the unit. No more than half of the crew can be composed of adult leaders.
Can I reserve multiple adventures of the same type on the same date?
For many adventures, yes. If you are reserving the same adventure type, your unit can reserve as many as are available for that date. Please review the 2027 availability guide linked above and the column “crews scheduled per day” to guide your selection.
Can I reserve multiple adventures of the same type on different dates? Can I reserve different adventure types?
Yes, but not all in the same reservation. You will need to log back in to register for each different date or different adventure selection.
Can I submit my next payment via credit card?
No. The initial fee is accepted by ACH (Electronic Check) or credit card. For all future payments, we accept ACH (Electronic Check) only. This helps reduce the price of your adventure.

Sea Base will not refund any fees to your unit if the adventure is not rebooked. Sea Base does not refund crews for canceled flights or ground transportation. Sea Base strongly recommends trip insurance.
