Buster (Hull 370 71 156) and Quadrium (Hull 370 72 167) are the same, but different than Catherine Ann (Hull 370 72 181).
Something changed between 167 and 181.
Cadoruca (no hull number since this boat was finished after the demise of Alwest) is the same as Catherine Ann.
See the attached picture of Buster and Catherine Ann side by side from the bow, but note from the transom picture that Buster sits about 3 inches higher in the water. I raised the waterline on Catherine Ann to adjust for the incredible amount of "junk" that we carry on board Catherine Ann
Comments from any other Alwest owners ???
