Possible hull number location.
Jon, I scanned the responses you got and don't think I'm repeating myself here when I suggest that you take a look at the underside of several drawers in the boat. For that matter, other bits of interior cabinetry might hold the secret. It was a common shop practice at Ericson to sometimes mark the hull number with a Sharpie on the drawer they were working on. I know as late as 1979 our E25+ had a drawer or two so marked. Slightly off topic, the original holding tank in our E31 had the same tank as the E25+ and was marked as such on top with felt marker. Ronco Plastics made the original tanks and still do for that matter. Let the search begin, Glyn Judson, E31 hull #55, Marina del Rey CA
Hi David,
Ours is a '73 but am reasonably sure the ID was in the same general area as was yours. It was located at the very upper left side corner of the transom.
Regrettably our transom developed gel coat blisters early on and was repaired under warranty without regard - thus wiping out the hull ID information. The only other "ID" info we have now is on our original '73 bill of sale and registration documentation issued by the state (FL) at the time. (Gel coat blisters and other issues/problems were common back then, so there's a good chance your boat may have been also repaired at some point and time.)
...Keep in mind, fiberglass boats of a larger size replacing wood (such as ours) were relatively new in the market place in the late 60's and early 70's. Our hulls are actually thicker than most of the newer ones as they didn't know for absolute certainty back then how strong the glass actually had to be - not to mention - we were before gas prices totally skyrocketed in the mid 70's and resins were cheap. This forced forced engineering advances in techniques, processes and materials such as Polyester VS Epoxy plus Ericson's "Tri-Axle" grid that also reduced building costs but improved hull design.
