On the Water Designs Swim Rafts are fine crafted with quality workmanship. Made of selected cedar, the frames are bolted together incorporating galvanized hardware and fasteners. The 5/4” decking is screwed in place using stainless screws. Utilizing BB brand flotation, allows the raft to sit only 7” above water allowing for easy boarding. The rafts have anchor hardware and access hatches built in to the corners. They are available in a pre-cut kit form, or completely assembled.
