Re: Stus-List 35-1 Cored Hull?

[Neil Gallagher via CnC-List]

My 35-1 has the same two bands, one at each end of the keel.  When I 
first got the boat the insurance survey found voids at the top end of 
them on one side where the raised part fairs back to the normall hull 
thickness, which had to be from the original layup as there's not much 
load at the top and no sign of cracks.  Nevertheless, my insurance co. 
made me fill those voids with epoxy...

This extra structure adds strength at the aft end of the keel in case 
of a hard grounding.

Re: Stus-List 35-1 Cored Hull?

[Martin DeYoung via CnC-List]

Based on the C 43 drawings I purchased from the Maritime Museum of the Great 
Lakes the C team learned from early hull experiences and added reinforcements 
on later hulls.

Maybe an earlier 35-1 owner reported an issue and the extra stiffener was added 
to later hulls.  From the pictures it looks well sealed.

As part of the ongoing restoration projects on Calypso we are adding the 
reinforcements shown on the drawings (some hand drawn in), especially just 
forward of the keel where we already repaired some fractures in Calypso’s hull 
back in 1999.  From several C 61 drawings I purchased, both hull #1 of the 
61’s and Calypso, hull # 1 of the 43’s had the same flaw and needed the same 
reinforcements.

I could not determine which hull number of the 43’s first received a “factory 
installed” reinforcement but I expect it was not in time for hull #’s 2 and 3.  
When launched, as “Arieto” in early 1971, our 43 was racing in the SORC within 
a few months.  I expect no mercy was shown regarding backstay and rig pressures 
in securing that year’s 1st in class (10th in fleet) wins.  It likely started 
to show some unexpected hull flex as difficulty in holding forestay tension.

IIRC hull #1 of the 61’s was Sorcery.  If so, I expect Sorcery was raced hard 
enough, with high enough hull and rig forces to precipitate an early issue that 
lead to other boats being inspected and the design team working out the fixes.

Yep.  That's the other side I referred to.  There are "mirrored" core
strips from about a foot either side of the centerline up to about the
waterline.

It seems to me there is a small section of core visible encapsulated like
that inside the storage area below the starboard settee in my friend's C
35 Mk.I (1973 vintage).
