You should also consider the Yankee 30, which is a close cousin to the Tartan 30. The Yankee has some nice properties compared to the Tartan:
* Chainplates go to fiberglass knees bonded to the hull instead of to wooden bulkheads
* It has huge cockpit lockers instead of interior quarterberths.
* There are vertical drawers alongside the hanging locker, which I think makes a little better use of the same space.

A downside is that the Yankee 30 is a little less beamy, and thus has a little less interior room. It also has less freeboard and windage, so it might be a hair faster.

Both are well built boats and have more in common than to differentiate them (including the great central motor location).
