I have a Lippincott 30 a 1981 I believe. I would like to find out about the never lauched hull in Rivertoon NJ. It is a GREAT boat. I would consider purchasing it just to get dry decks, etc. Ours sails stiff due to ballast vs displacement and fast. She points very high. 4000# balllast for a 8600# displacement. The D/L is 246 and the SA/D is 17.3 so it has good power.
We wish they had made a lot of 36's. I understand there were only two. As usual a slightly bigger boat would be nice. Dickerson's are a similar or the same hull.
I seem to remember an article by Tucker Thompson in some mag about a cruise in an L-30. Goggle it for another view.
The Lippincotts produced a great boat consistent to the technology of the time. The fit/finish on ours is still beautiful. On older ones you need to be realistic on the upgrades that may be necessary.
First is the wiring and the electrical systems in general. Small Yanmars, 2 batteries, limited circuits. Consider boosting your storage with say two batteries on your house bank and keep a third for starting. At 20-30 years, you may want to rewire the boat as well. Using more efficient nav and interior lighting will greatly extend your usage as well. More storage capacity should be augmented with a bigger alternator and appropriate charge controllers.
The holding tank is joke for anything other than a daysail. Some of the space under the V-berth can be used for a larger holding tank. Water is in Fiberglass tanks under the settes. It's enough for about a week for our family, but we drink from bottled water we carry aboard.
The sail controls may not have been modified. You should invest some time/money and effort into a rig survey for both the standing rigging and also to learn about optios for sail control/reefing. Original winches were non self-tailing. That alone is a great but expensive upgrade.
The engine on our boat is more than adequate. Our's is a 15 hp 2GM (2 cilinder) Yanmar. The fuel tank is small - 10 - 12 gallons. I recommend a larger tank. Plenty of room to add one. The cockpit lazarettes are huge and allow access to the fuel tank. Our prop is a two blade and I have not wanted to make a change because the performance and handling are more than adequate to great.
This boat would not be a good dockominium. But it makes a terrific low cost fast stable fun cruising boat. For us it is a great starter boat for our young family to get used to cruising on.
