Hi Allen, We found a brochure for the original 27. It reports the same specs as the 27/2 and 27/3 so the hull appears to be unchanged with the subsequent versions. They report a sail area of 328 sq ft for the original 27. That increased to 380 sq ft for both the 27/2 and 27/3. However, from what we can tell, the rigs were the same, just the genoa’s overlap increased.
All that said, Com-Pac is still in business. Reaching out to them would be the best way to confirm any differences.
Hope this helps.
