For help; Lavro’s scribed the serial number up under the rolled gunnel on the stern, starboard side. The first or last pair of numbers in the serial # was the build year (can’t remember which, but if there’s a “89” for example, it was built in 1989). They made them in 48/54” wide bottom models…all of this is from memory now, but should be fairly accurate. Lavro’s measured down the center, Eastsider’s measured along the curve on the side. A 16’ Eastsider was about a 14.5’ boat IMO.
