These solid sport tenders have been a staple in the Achilles lineup for over 30 years. Achilles have modified the tube design of these models to incorporate a lateral seam, giving the boat a sleeker, more modern European looking design. In addition we have changed the floorboards on the SPD–E series so the rear 3 boards are now aluminum and only the front 2 bow boards are painted marine plywood. This results in a new floorboard system that will require less maintenance and offers increased durability. The combination of these changes in the hull/tube and floor design offer improvement in both style and performance.
