The rig dimensions above are from the 1963 sail plan drawing. Current class rules (2005) allow a max of:
I – 46.7′
J – 15.3′
P – 40.1′
E – 17.55′

The accolades for this particular boat are many. Certainly one of the most influential designs and successful racing boats ever. With 160 built, it was also a commercial success for Jensen Marine.
Less mention is made of the man, George Griffith, who actually commissioned the design, and agreed to back the construction of the first ten boats.

This added note from Robert VanderPol II:
“There is a single example of a raised deck Cal 40 similar to the Cal 25 & 28. Jensen Marine was promised a number of orders. All but one backed out at the last minute and only one was built and delivered.”

Different design from ERICSON 35-2.
Shoal draft: 5.0′
Short rig:
I: 43.0′
J: 15.8′
P: 36.7′
E: 12.0′

Design credit for this model was never listed in any of the promotional literature. But the similarities to the earlier COLUMBIA 40 seem obvious.
A keel/cb version was also offered. Neither version was built in great numbers.
A later, entirely different COLUMBIA 39 was introduced in 1970.

First introduced as the MORGAN 38 though entirely different from the model by the same name that came out in 1969.
Updated in 1981 with a taller rig, modified rudder, larger water tank, and numerous changes to the interior.
Updated again in 1983, it became the MORGAN 384. Catalina Yachts purchased Morgan Yachts in 1985, but this latter model remained in production for another year. Approximately 500 boats were built under it’s varying iterations.

According to the original literature, the PEARSON 36 was designed with with the “IOR 1 ton rule in mind”.
An entirely new PEARSON 36 was introduced in 1985. (listed as PEARSON 36-2)
