I'm on a Catalac 12m, that needs a new mast.

The original mast is a Kemp E224: 224mm x 150mm (8 7/8" x 5 7/8"), 4.5mm wall thickness. Kemp was subsequently bought-out by Proctor/Selden, who continued to produce the E-section, until recently discontinuing their E-section line. So, ideally we're looking for a new or used (good condition), 40-foot E224, or something close to the above footprint dimensions.

The Z-Spars Z701 is reasonably close at 232mm x 145mm, 4.0mm wall thickness, being slightly longer and slightly narrower, but that model has been likewise fairly recently discontinued.

I'm presently in Northeast Florida, in the Jacksonville/St. Augustine region.

Any help or suggestions would be greatly appreciated.
