Philbrick Boatworks, now under new ownership, has recently contracted Coastwise Marine Design Inc. to design the powering and arrangement of Don Philbrick's classic 18' runabout.  A 3D hull surface model had been previously created by Jim Frankin Yacht Design. CMD modified Jim's model to accommodate a 6.2L Mercruiser gas inboard coupled with a ZF45A down angle gear.  Planing analyses were performed by Orca3D software to optimize cockpit location, and engine installation.  Fuel capacity 40 gal. The hull has been built by the Northwest School of Wooden Boatbuilding
