My list
Here are the things I need to know about my '77 h27:1. Hull integrity - Main sink drain, cooling water intake, speedo, and depth guage all penetrate the hull below the waterline. Loose/worn cockpit drain hoses have also caused flooding on Lady Lillie.2. Fresh water - Original equipment is an aluminum tank under the v-berth, and pumps at both sinks. 3. Our head is a porta-potty with a pump-out built in. This is a great system, but Marine toilets and holding tanks were also installed.4. Bilge pump - Ours is a hand pump built into the port settee.5. Electrical - 12 and 115 volts. Our panel is to the port side of the engine by the floor. There is a 115 breaker in the port locker under the chart table, and a 115 shore power connection on the port side just forward of the cockpit. The 12 volt battery is under the forward end of the quarter berth. There is also the grounding wire from the mast to the keel bolts.6. Alchohol Stove - ours is a pressurized model. Most suppliers are still in business, and you can find manuals online.7. Engine water cooling and exhaust - most are straight-through raw water cooling systems, but some have self contained cooling and support a hot water system. The later is usually a prior owner mod.8. Diesel engine - usually a Yanmar SB8, but sometimes a Renault. The Yanmar is well supported, and you can get a manual from Torresson and others.9. Radio - These differ according to prior owners, but there is the radio itself, the antenna cable with a disconnect at the mast step, and the antenna at the top of the mast.10. Steering and rudder - we have a tiller - a pretty obvious system with no tricks. Others have a wheel, so I'm not much help.11. Rigging and sails - I'd have a rigger out to look at your standing and running rigging. Same thing with the sails. A sailmaker should come for free, but you might have to pay a rigger. The reference books sited by others also have good info on inspecting these systems. The spars are straightforward. There is a set of antenna and lighting disconnects inside the mast step when the time comes to take down the mast for whatever reason.12. Deck hardware - winch makers all have manuals online, and reference books will tell you how to clean and maintain them. You may have an anchor locker forward - we don't however. The anchor would be stored below if you don't have a locker. Lady Lillie has mid-ship cleats added by a P.O, that are a real plus.13. Prior owner stuff - in 27 years, various prior owners have certainly added or modified your systems in all kinds of ingenious ways. Basically all or none of what I have described above may be on your boat. So talking to dock-mates with good old boats is relevant, even if they have a different model. The reference books already cited are a real help. Then you will crawl all over the boat, jot down product names, and surf the web or check the archives here to figure out exactly what you have. Might as well do it sooner rather than later!But do spend some time sailing the boat! This is a great cruising model with pleasing lines, a good dry ride, good speed on a reach, and good room for two. (We have done four large men for a week, but you had better be real friendly!)DavidLady Lillie
