tool stretching
Lew,
Per my last post, Martin has given you the scoop on the 39/39B.
I can tell you about the 30-2's evolution. The original outboard rudder, masthead rigged 30-2 (a really good boat BTW) had run its' course and that size was due for an update consistent with the desires of the market at that time. These things included wheel steering, diesel engine, fractional rig, and "modern engineering".
The TAFG grid structure was first developed for the 30, and basically the tooling as kept-the biggest changes being the transom was narrowed a bt, the rudder became part of the boat, and instead of the old style wodden bulkheads, the new TAFG was laid into the hull for load bearing. And the 30+ was born-many new features, but the hull and most of the deck were from the older 30-2 (Although a new tool was built in very short order-the shape was basically unchanged).
Next came the requirement for a smaller boat that would keep the same popular features as the 30+. The hull was chopped 2 feet forward of the stern, and a wide back end was fitted-along with MINOR changes on the deck layout, and blam! The 28+ emerged-which later became the 28, and I don't actually know what the differences are between the original 28+ and the later 28's.
This happened during my time at Ericson-as to the best of my recolleciton is how this was done-eseentially the same tool was used for all 3 models..
Class? Anyone? Anyone? Bueller!!!!
Cheers,
