Any pinched end IOR-influenced design is going to be touchy downwind, and the rudder
on a Mk. I is a little antiquated. I own a 1973 Viking 33, also a C&C
design, and the two boats and the C&C 34
are really quite similar.
The problem is not the rigging
, but the whole way it ties together with that old, often frozen balsa core deck
. You have to bed
and inspect and rebed and rebolt the chain plates, and probably have to recore the deck
and install backing plates
to beef up or refresh the original arrangements. Obviously, if the rigging is 35 years old and from freshwater, it goes into the "spares" category, along with all tangs and pins, etc.
But the fixed portlights
are weak, and the hatches are sub-par for offshore
. I won't even touch the likely Atomic 4 engine
and the ten-gallon gas tank and the unlooped ventlines and the 1970s Romex 10 gauge house wiring
on the AC side.
You already likely know about that.
Don't get me wrong: the C&C
30 is a great inshore, lake and coastal boat. They still win club-level races. But they are not in my view adequate or safe for offshore
. Not with 1/4 inch plexi in weak frames and tired rubber in the Atkins and Hoyle forehatch and smoked Lexan
dropboards and Barlow winches.
You want to stay within sight of land with all that in a 35 year old 30 footer. You could beef it up to make it safe, but you could also buy a more appropriate boat for offshore.
