Backwoods Boats models features a smooth heavy gauge aluminum hull made of Marine Grade Alloy (.125 inch) with no crimps or keels, unlike most adventure boats on the market today. Our custom design uses longitudinal and horizontal braces that run from the bow to the stern. This bracing allows for strength and flexibility to withstand any environment your adventure takes you to. By implementing this design our boats hold their own on the water and give you peace of mind that there is strength behind the build.
