Solid GRP and encapsulated lead ballast

Three more:

The Twister's big sister, the Rustler 31. She really is just a big Twister. A really excellent boat. And the very beautiful but rare Northshore 34 - same boat with a counter, or you could call her the GRP Shaker (Kim's own boat) (moulds were destroyed in a fire).

The Nicholson 31. Said to sail and handle better than the 32, but let's not go there...There are no bad Nicholsons designed by Ray Wall... (biassed... moi??)

But Nicholson 31 and Rustler 31 both have cored decks, right?
Can't find any info about Northshore 34 ...

Vancouver 27, 28,32 and 34 although I think the 27, 28 and 32 were encapsulated cast iron and the first 34s were also the later ones were lead. I have never heard of any structural problems with the internal cast iron keels although the first 34s were slightly stern heavy and dragged the stern noticeably under power that was corrected by a lead keel and the ability to move the ballast forwards slightly.

I like the Vancouvers very much - but they have cored decks, right?

Marieholm 32. Though I am sure she had some wood within the deck.

In fact, do your research carefully, a good number of the boats mentioned had some form of stiffening on deck or coachroof. In the early days this might have been sheet material that was, for all practical purposes, fastened to a solid deckhead using GRP as an adhesive. This is fairly easy to live with and in the unlikely case of it becoming damaged can be repaired without too much grief. True cored decks are potentially far more sinister.

It should also be borne in mind that not many of those boats had lead ballast. In my view it is one of the touchstones of the designer's intentions.

The Marieholm 32E i like very much but hard to find one
 
So to sum up:

Contessa 26
Great Dane 28
Freeman Deep Seadog 30
Barbican 30
Hurley 9.5
Elizabethan 31
Contessa 32
Nicholson 31 ?
Contest 31 ?
Nicholson 32
Rival 32 (iron ballast ?)
Rival 34 (some have iron ballast ?)
Nicholson 35

Did you mean to say Northney 34? Here is a cracker:

Lovely, lovely boat when seen on the water. There is one moored in Fowey and I always admire it in passing
 
As you've listed the Nicholson 35, you might also add the Hallberg-Rassy 352 to your list. Encapsulated iron keel, solid GRP hull, Divinycell cored deck, well engineered, nicely built. I had one for almost 20 years, great boat. And I suppose you could also add the HR312.

If you read the OP's post he does not want cored deck, which makes a number of the suggestions pointless

Yes, I saw that, but there aren't many uncored decks, so I guessed that he was probably averse to balsa-cored decks (as indeed I am). The Divinycell used by Hallberg-Rassy as a core material won't absorb water and won't rot.

Yep, We have a 1980 Trintella yacht with Airex cored deck. We removed the teak deck a few years ago. The ply core under the windlass was rotten so we needed to remove the grp sandwich to replace the plywood. We cut out out the section with a grinder which also exposed some of the surrounding Airex foam. It was in perfect condition although butted up to marine ply you could scoop out with a spoon. Decks cored in the right material with good workmanship are excellent.
