About the Ct 35 Sailboat

With limited documentation available, the Ct 35 represents one of the more elusive designs in the 35-foot sailboat category. This relative scarcity of information suggests either a limited production run or a design that remained within specialized sailing circles, making it an intriguing prospect for sailors seeking something distinctive. Based on its length designation, the Ct 35 would typically fall into the coastal cruising and club racing category, offering a balance between performance and comfort that appeals to sailors looking for weekend adventures and occasional longer passages. Boats in this size range generally provide enough interior space for a small crew while remaining manageable for single-handed or couple sailing. The mystery surrounding this particular design could work in favor of prospective buyers who value uniqueness and are willing to invest time in research and potentially sourcing parts through specialized channels. However, the limited available specifications mean that anyone seriously considering a Ct 35 should conduct thorough inspections and seek out existing owners or sailing communities that might have hands-on experience with the design. This approach becomes particularly important when evaluating the boat's construction quality, sailing characteristics, and long-term maintenance requirements.

High
The deck-to-hull joint on CT 35s built by Ta Chiao is an inward-turning flange bedded in polyester putty rather than a proper marine sealant. This joint is prone to weeping, and water intrusion can migrate into the balsa or plywood core used in deck sections, causing soft spots particularly around the toerail and chainplate areas.
High
Ta Chiao used balsa core extensively in the deck construction, and moisture intrusion around deck hardware fittings — cleats, stanchion bases, and winch pads — is extremely common due to inadequate original bedding and the use of through-bolts without proper backing plates. Tap the deck carefully for soft or delaminated areas.
High
The long keel is encapsulated ballast (lead or iron depending on build), and the garboard seam area where the keel meets the hull can develop stress cracks and weeping on older hulls. The keel-to-hull joint should be closely inspected for separation or repair history, as this area sees significant stress in a full-keel boat.
