ERS FIN boxes are engineered for any water environment, but like anything with connecting parts they require some care for optimal performance and longevity.
For boards with removable fins, added weight should not be placed on the board while it is on a solid surface. This includes not standing or laying on the board, and attention should be paid to kids and excited large pets jumping or climbing onto it. An installed center fin is not designed to support weight on land, and significant damage can occur if weight is added and force applied. It is best practice to have your board on its side or, on soft surfaces, fin side up. The LRC™ fin box can handle the weight of the board so as long as further weight isn't applied, so it is safe to leave the board deck pad side up briefly while you prepare for entry into the water just heed caution around others.
Please ensure when launching that you have plenty of clearance for your fins in the water before climbing onto your board. Replace any fin that has been damaged or is showing signs of deterioration. This could compromise performance and pose a potential safety risk and damage from snagging on unseen objects.
Avoid bending the fin boxes when folding the board for transportation. For correct board folding technique please see www.earthriversup.com. Fin boxes can be replaced in the event of damage, though it is a difficult job that can only be performed by an expert skilled in the technique. Do not attempt to remove or replace any fin box by yourself it could cause irreparable damage to the board and result in injury due to the tools required.
