There was definitely one in Rock Hall, MD as of May, 2014 as I laid eyes on it myself and talked about it with Tom Lippincott of Salt Yacht Brokerage when selling my L30. He informed me that it is privately owned, outside of his family.
VERY interesting though I'm not sure I see the point. Other than the well above average quality interior fitout (which is a major selling point), there isn't much that differentiates the Lippincotts from other production boats of the early 80s. Assuming a brand new L30 was finished to it's original quality level, it would be in competition with the likes of the Harbor 30, which has a modern rig and hullform, and the Seaward 32, which is a very different boat but does offer its own advantages. And. depending on how it materialized, it would also compete with low-30s offerings from Bene/Hunter/Catalina. I assume the sales price of a new L30 would be in the mid to high 100k range and I'm not sure how many people would want to pony that up for a boat based on a 35+ year old hull design.
It would be interesting to hear what your contact envisions a brand new L30 looking like, the market demand it would fill, and the proposed sales price.
