Solid GRP and encapsulated lead ballast

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

Balsa cored but I never saw any problems with mine nor aware of any. It begs the question of what gives you concern about it? If on survey a boat is good then if you maintain it it should stay good and you should be able to detect a problem with the deck prior to official survey.

I can't think that you will find a solid GRP deck anywhere.

Can't speak for the rest, but the Rival 32 had encapsulated iron ballast. Most Rival 34s were the same, but a few had lead.

I’m pretty sure my Rival 34 had lead ballast. It was one of the last built (1988) though. A boat I can thoroughly recommend: strong, seaworthy, go anywhere and beautiful. Not roomy or fast by today’s standards, but the OP does not mind, judging by his criteria.
 
Island Packet's have fully encapsulated lead keels, shallow draught and closed cell IP Patented closed cell core for the decks and coachroof.

Some early small ones did have lifting keels, but most are as above.

encapsulated iron keel for shallow draft (4'8") R34s, encapsulated lead keel for deep draft (5'6") R34s
 
It looks like the early Rival 31's were solid glass and later models a composite:

"Anyone ever had to replace the core in the cored bit of deck at the bows on r34 of mk111 32 ? If so, how nasty a job was it ? A recent survey i've seen on a 34 is showing high moisture readings in this area both on deck both above and below, indicating that the area is saturated and possibly rotten. Instead of replacing the core i was thinking of a soution where the core is replaced with stringers like the earier versions ? What do you think ? "

It's a tough ask, I know this because I conducted a similar buying exercise a long time ago. The Contessa 32 always had a solid deck and lead ballast in an encapsulated keel.

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.

I am not really against cored decks - but I wanted to create al list of boats with solid FRP decks.
 
So standing right now:

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

There is some balsa in the deck of an R34 alongside and forward of the forehatch; nothing further back, just stringers and a solid deck. Plans available on the Rival OA site (membership needed to see them)

Why do we think the Twister has a cored deck? The scantlings specify 9oz of glass in 6 layers with no mention of core.

No. I know mine doesn't have a cored deck. It is solid GRP with timber stiffening battens bonded under the foredeck, and under the aft deck. This is shown on the designer's plans, which I have in front of me now. The deck thickness is specified as 9/32" and the hull thickness generally as 5/16" increasing to 9/16" down the sides of the keel moulding.

The plans show 4480 lbs of lead encapsulated in the keel.
 
I’m fairly sure that all the Camper and Nicholson GRP boats have encapsulated lead ballast. I am less sure about the decks; all I can say is that tapping my boat’s deck it seems to be much the same all over and given the usage it has had if it were going to go soggy it would surely have done so! All “C&N”. GRP boats were actually moulded by Halmatic and all except the very first ones were also outfitted by Halmatic, so perhaps someone with connections to Halmatic will know?
