Matt, I have noticed the same limber hole issue in Calypso’s bilge and dark hidden spaces. I have been able to improve the function in many place but not all. Fortunately I did not need to remove any prior owner’s work as it appeared original. When we were installing the reinforcing “I” beams we made an extra effort to shape the bilge to promote water flow to the bilge well.
One of the last significant bulkhead repair project I need to complete was caused by one of the “built in”, sealed nooks under Calypso’s nav station. I discovered the sealed space when exploring how far the bulkhead rot extended. I suspect the water in there was part of the rot source. The way Bruckmann’s crew finished out the companion way slider and spray hood eventually allowed water to drip down into this space and the rotted bulkhead area. I rebuilt the failed structure under the slider with G10 epoxy board (no rot concerns) and carefully shaped the space to allow the inevitable water collecting there to flow out onto the deck. Of course when I had that part of the boat torn apart I reinforced areas of high load under the traveler to be sure the loads were still shared by the adjoining structures. Is your 42 an original design or a iteration from the 43? I heard about one of the later 43s (maybe Night Train?) that was built with the keel shape modernized. I also have heard that the 43 Opus in Vancouver BC is a modernized version of the older 43 design. I expect the newer keel increases the performance sailing to weather and in lighter conditions. Back in 1974 Calypso (as Arieto) was modified to rate better under IOR and added a new, deeper rudder. The modification, bobbing the stern, was designed by C&C. I have a copy of the drawings used in case I have the time and budget to restore the stern to its original shape.

My boat has all kinds of nooks and crannies where water accumulates. One of my pet peeves is that often the limber holes were not placed at the bottom of the area being drained, but instead a half inch or so above (such as just forward of the mast). As a result, the half inch or so of water doesn’t drain. I prior owner used Bondo to address this. However, I discovered that water works its way in under the Bondo. I plan to remove all the Bondo and level the various areas with West System. Another job on my long list.

The “stick built” interiors give both easy access for water migration and for the repair work water migration makes necessary. I have a declared value marine insurance policy to cover liability and some hull losses but fully expect a tussle if I were to file a total loss claim. One of the key failure modes we experienced was caused by water gaining access to the channels created when the Bruckmann build team bonded bulkheads to the hull. We found water** that pooled in the bilge forward of the mast migrated across the bottom of several bulkheads and, over 40 years, rotted the ¾” thick plywood up to 18” from the hull contact. Did you find any evidence of water migration through the bulkhead channels of the embedded 12v wires run through the deck balsa core? Maybe Bruckmanns build practices were updated by 1973. Martin DeYoung Calypso 1971 C&C 43 Seattle/Port Ludlow **Calypso’s excess water forward of the bilge was cause by hull laminate fractures likely caused by years of hard competition and excess use of hydraulic backstay/babystay adjustors. When we first launched Calypso in Seattle (after trucking out from Chicago) water seeped into the bilge space forward of the mast step. We re-hauled the hull (the mast was out for painting and new rigging) and started diagnosing the failure by chiseling out the orange polyester “bog” filler and grinding off bottom paint. The micro fractures became appearant most easily inside. We re-laminated the hull in that area with epoxy, built up the well forward of the mast step, and re-faired the hull. Using as built drawings from C&C (from the museum I bought all available for 43s and some for the first few 60s) during Calypso’s current restoration we discovered 43 and 60 hulls after #1 and #2 were retrofitted or built with extra reinforcement in this area. For Calypso we manufactured “I” beams from G10 epoxy board and wood then glassed them to the hull from next to the mast step forward past the babystay’s interior anchor point.
