older Helms better
I have made it a point to continually ask each (interrogate) owners about their Helms. I believe that the oldest or first built Helms boats were build for racing perhaps more than cruising. It's just my belief that Jack (an olympic sailor) built his boats to race, as a builder he was also subject to the pressure of the buyer. The later models included a galley, sometimes a pop-top cabin complete with camping tent and other itmes to make his racer more appealing to the family (read wife) sailor.
The earlier boats (25'ers) drained the cockpit from the front of the cockpit, later drains were located close to the stern. I have located my Helms (75) alongside Odalisque (73) and the hulls appeared to be exactly the same, I only viewed them, I didn't measure them in detail. I know that the Port & Stbd. hull lines of mine aren't exactly mirrored, my lifelines are different lengths, the rubrails are different lengths.
