Explanation:

While going for boating for any purpose either recreational or work, all the individuals on the boat are required to have the access to following safety gears as per the norms of U.S. Coast Guard.

1.There must be access to life jackets/ flotation devices to each and every member on the board

2.Every member on the board must be aware of location and usage of fire extinguishers in times of emergency

3.Likewise visual and sound signaling devices must be accessible to everyone.
