Nauticat 38 Chainplates Pulling Through Deck?

[Anonymous]

I’ve recently become the owner of a Nauticat 38 and have scoured the net for information on them. Most is very very positive but I did find one person saying they had heard that “they sometimes suffer from the chainplates pulling through the deck”. This surprised me, given that I’ve seen how thick the deck is on this tank! Is it something I should be concerned about?

I’ve looked again, but I can’t find the link.

Thank you!

Having looked through the technical issues raised over the years the only reference I have found was on a N44 and the following comment made by Richard Bartlett in 2005 (the Technical secretary then).

Early build NC44 reported chain plates visibly lifting from the deck whilst on overseas passage. Boat docked near to Nauticat Agent and investigation still in progress but overstressed rigging is suspected.
Siltala ‘beefed’ up these anchor points on later models so we can assume that this potential problem is confined to a small number of pre 1985 boats.

Ours is a 1978 build. I’ll keep an eye on things when we’re next out and the wind is up a bit. Thanks for the reply.

We had a Nauticat 38 and the chain plates to the mizzen had domed upwards. After losing the main mast we had the chain plates exposed and found they were inadequate. We had larger ones fitted and it is still O.K. after 20 yrs.

Are these the ones which are secured on the inside in-line with the bulkhead which forms the aft wall of the aft heads? On deck, just aft (about 2″) of the wheelhouse moulding most aft protrusions?

Yes sorry for delay, but lost access to the forum.  They caused no more problems afet that, but it mesant stripping most of the aft cabin to access them and complete the work.

No worries. Thanks for getting back to me!

Do you have any photographs before/after or both of the inside view? I’m keen to know if I ought to do something to beef mine up, or not.

Hi there, we have just acquired a 1986 33 cutter rig and have a similar problem with the aft lower shrouds to the main mast causing the deck to dome upwards. Our surveyor thought it was over tensioning so I have slackened them to monitor the effect while we are laid up. Anyone else seen this on a mark 2 33 footer?
