Aluminum Floor Installation Instructions:

1. Review Installation Steps: For detailed installation instructions, please refer to the aluminum floor installation guide.
2. Inflating Boat Tubes and Keel: Before operating your boat in choppy waters, ensure that the boat tubes and keel are fully inflated to the maximum recommended pressure to prevent damage to the floorboards. For more information on air pressure, please consult this FAQ section. Underinflated tubes and keel can lead to aluminum floor cracking. Please see different FAQ for more info on that.
3. Preparing to Install Stringers: When installing the stringers, position the oars beneath the bottom of the boat to elevate the edges of the floorboards off the ground.
4. Installing Stringers: Stringers are designed to connect two adjacent main floorboards. Each main floorboard consists of smaller sections that are joined by C-channels at the edges. For optimal alignment, ensure the spaces between adjacent stringers do not line up with the joint lines between the smaller sections of each floorboard.

Quick Tip! Worried about the weight of a hard-floored boat? No need to strain your back! Pick up a foldable hand cart from any retail store to easily transport your folded boat. Even budget-friendly dolly movers work wonders for both folded and fully inflated boats. For extra ease, consider our dinghy dolly wheels—perfect for rolling your inflated boat across the shore and right into the water!
