Solid fiberglass.

The hull is solid glass, no coring. On my H37C it is also very thick I learned when drilling for new thru-hulls and transducers. The decks are mostly cored with end-grain balsa. When removing portlights you will find that they used plywood in the cabin trunk sides. I was surprised to read some of the recent posts where guys found aluminum plates imbedded in the hard spots, where deck organizers are attached for example. On my H37C the winch and cleat are thru-bolted but the deck organizer was screwed into plywood. Same with the traveler in front of the mast. Big winches and cleats are all thru-bolted on the H37C.

what year H37

Ed What year is your H37? I have aluminum plates embedded in the deck at locations for deck hardware. It's a H27 1984. No leaks or stress crack. I am normally a thru bolt type guy but I am installing some additional deck hardware and will be using the drill and tap method.

Lady Lillie is solid fiberglass for the hull, going from less than 1/4 inch at the toe rail to about 7/8 inch at the keel. The deck and cabin roof are a sandwich with balsa coring. I have heard of plywood coring being used in some places/boats. David Lady Lillie

Dan, a '79.

My H37C is a 1979. Guys that have added deck hardware agree with you, thru-bolt 'em. I have owned all the hardware for bringing lines back for years. I cannot make myself drill those holes. Winches, clutches, deck organizers, and blocks sit useless in my basement. And I love my clear decks. But for safety reasons I know that I need to get at least the halyard back there.

fyi

My 37, 1985 has plates in the deck for cleats winches and organizers. they are have been tapped and have been no problem at all. But is was sure suprised when i saw no bolts on a couple of cleats that came thru.

Plates

Ed A. and Ed S. My H37C, 1984, also has aluminum plates in key positions like under the deck winches. I notice that my mainsheet winch is thru bolted on the cabin top but all the cockpit winches are tapped. I am not sure if there is aplate under that winch but there are nuts on the thru bolts. I also was surprised when I noticed there were no nuts on the bolts from the winches. I called Hunter about it in 1986 and they said there was an aluminum plate under all the winches. I am not sure about the deck. Like you, I have still never installed the deck hardware to lead the halyards aft. Fair winds.

Ed Schenck, drill the holes!

Ed drill the holes and mount your hardware, you won't regret it! (making the first hole is the hardest!) Chris

Where are the plates on the cabin top

on the 37C? I found the ones on the aft end of the cabin top , when I mounted jam cleats to bring the traveler lines inside the dodger. Any others, foreward of cabin top traveler?

About the bolted down winch,

It may be someone stripped the threads in plate and had to drill it out and bolt it.

help

I have a h27 1982 main sheet block has a striped machine screw. does this backing plate have a nut on the backing plate or is it threaded through the backing plate? I also have a bolt on the mast tabernackle that will not tighten. Is their a bolt under the plywood on the mast step? Are you able to get the nut to rengage the bolt?

Through bolting

To my knowledge, there are no aluminum plates embedded in our '77 h27, and with the traveler at the aft end of the cockpit there was no hardware mounted on the cabin roof. I mounted hardware and a winch to lead two lines back to the cockpit by through bolting all the hardware using the "drill/fill/drill" process to seal the balsa core from the new holes. Then I mounted a grab handle on a piece of cherry to cover the washers, nuts and bolts on the ceiling of the cabin. Through bolting is easy, and effective for deck hardware, and I recommend it if the previous attachments fail, even if there is an aluminum plate. Second best would be moving up to larger bolts, and redrilling and retapping the plate to be sure you have the threads to hold them. Gary, the bolt at the mast tabernacle was probably a prior owner addition. In any case, you need to check for wood rot in the hole. And, I doubt that there is a nut down there, so you are going to have to start over somehow. At the mast, I would recommend installing a plate under the insert/step that holds the mast. That means taking the mast down, pulling up the insert/step piece, and inserting a u shaped plate under it. Then, you would have a known, clean hard point for current or future turning blocks. I found a couple of cheek blocks (stainless plates holding blocks, mounted on teak with a curved side to fit the mast) in my rigger's trade-in box, and mounted them on the lower mast to turn the lines to the organizer on deck. That's another idea for you. David Lady Lillie

On the 1982 h27 the mast step has 4 machine screws holding the step down to the deck. How are they anchored?

aluminum hard points

I have an 1984 H27. This year boat has aluminum hard points glassed into the deck for mounting hardware. I think it is about 3/8" of an inch thick. All my original hardware was installed with machine screws at these points. I do not know when Hunter started adding the aluminum plates. It appears some earlier boats do not have them. I just added some new hardware by drilling and taping into the plates.

Mast step bolts

Mine are fastened right by the compression post (just forward and starboard of it.) by nuts and washers that penetrate the complete step structure, including the cabin liner. David Lady Lillie
