This bsr360 BRIS inflatable boat is made of 1100 denier 0.9 mm PVC fabric with an aluminum floor board and marine plywood transom. It is a much more heavy-duty PVC fabric than most 1000 denier PVC boats. This boat has round end-tubes for better performance. We also have added double layers of fabric at the bottom of the tubes. This allows 1.8 mm of lower tube protection from sharp rocks and abrasive sands. This boat is lightweight and does not take up much space once deflated. It can take up to a 20 hp short shaft outboard motor and can carry up to 3 people maximum. The bsr360 is great a tender for yachts or sailboats. It can also be used as a lifesaving raft in case of an emergency.
