Macoupin Boats the product of Lake Rip Rap, Inc. 2011 Lake“Macoupin Conference Mechanical Riprap Boats” Building & Operating Macoupin Boats for Shoreline Stabilization
Hank Sutton (217) 899-9706 [email protected] - www.LakeRiprap.com - www.MacoupinBoats.com Shoreline erosion control using conventional equipment can be very destructive.
Macoupin Boats working in the Shawnee National Forest with no environmental damage to the wooded slopes. . Shoreline work can be done by boat with no damage to the upper bank. Designing a Macoupin Riprap Boat Macoupin Boats Design & Calculations: Structural Hull Design Determine Empty Weight Total Displacement & Free Board Centers of Gravity: . longitudinal, transverse & vertical . (loaded and empty) Center of flotation
Confirm Lateral Stability Draft: . bow draft empty & loaded . stern draft, empty & loaded
Other considerations Hydraulic Requirements Electrical System Propulsion Transportability Launch Methods Shop Equipment used for building Macoupin Boats Tools for cutting steel
Hydraulic shear Multi function shear/ punch
Power hack saw Mitre saw Tools for cutting steel components Heavier parts are cut by CNC Water Jet at 90,000 psi. Other Metal Cutting Methods:
Plasma Cutter - makes a clean straight cut when used with a straight edge
Track Driven Torch - used for long cuts in steel plates that exceed the capacity of the hydraulic shear
Hand held Torch - generally used for minor trim to fit Various Size Drill Presses Various Size Press Brakes for bending steel plates generally used for making non-standard size & custom fit structural shapes Lathe - generally used for making drive shafts, cutting journals & shoulders Two overhead cranes MIG Welders Hydraulic Hose Machine Fabrication this plate weighs 3 tons
Special Order Oversize Plates for Bottom of the Boat reduces welding
Cut-out for tunnel hull Laying out the bow radius on the side plate Laying out the bow radius on the side plate
Side plate lifted into place by an overhead crane
Floor stringers Hydraulic Press Brake Forming the Bow Radius Plates Installing center radius plate Center radius plate installed To be Cut by Plasma plasma cutter
Cutting deck drain with a plasma cutter Sub-structure painted before the decking is applied. Bottom of the deck plates are painted before installation Conveyor frame and rollers Emergency shut- off switch
Emergency grab cable Conveyor drive (before safety guard installation) Conveyor lift cylinders - equipped with a load lock for safety… if we blow a hose, the load lock prevents the conveyor from falling Conveyor belt tensioner Hopper Construction

Macoupin Boats… Macoupin 409 - Otter Lake Special Just flip a switch - the boat unloads automatically
Macoupin Boats… Macoupin 420 the next generation Macoupin Boat
The next generation boat with an over-size conveyor is designed to unload 20 tons in 90 seconds This will result in a 20% increase in production

After ice-out, weak sloughed soil is quickly removed by wave energy.
Without protection, this is an on-going annual occurrence. 2002 - sloughed soil 2001 isolated from wave energy

BEFORE TREATMENT: 12 plant species – very sparsely populated, with no significant wildlife habitation
4 YEARS AFTER TREATMENT: 121 naturally colonized plant species; 49 invertebrate species; 25 reptile & amphibian species; 8 mammal species; 12 bird species; and 9 fish species (scientifically identified)*
