Want to jump in and ask about the space on the tartan compared to a catalina 27? I love the look of the tartans, bristols and cape dory. Worried about sailing in light wind conditions and the difference in space.
Often, newer boats made better use of existing space. The Catalina 27 is also just a bit wider, which gives more cabin volume.
The T-27 has a better SA/Disp ratio, so it might sail a little better in light air.
The C-27 is also offered in a "tall mast" configuration, which raises it's ratio, probably making it better in light air.
The T-27 is also offered in a yawl configuration, so ditto on the better ratio.
The T-27 also has a centerboard which is an additional maintenance item, but the shallower draft with the board up may appeal to you if you're gunkholing.
Hope this helps.
