I'm interested in a CD 30 Ketch that's for sale locally. The boat has a Yanmar YSB12 engine and V-drive. I have a couple of questions:
Is this a one or two cyl. engine?
How does this configuration work (vibration, access, reliability)?
How difficult is a retrofit with a more conventional engine layout?
Any opinions on the ketch rig would also be appreciated.
Thanks for your help.

Re: CD 30 Ketch
Steve,
The Yanmar YSB12 engine is a one cylinder. Mine is 21 years old and works like a champ. Noise level in the main cabin at full throttle is high, but not in the cockpit. Access is reasonable ( once you climb into the cockpit locker). Retrofit with a more conventional engine layout? I understand that later models used a Volvo or Universal. Because of the low shaft angle I believe a v-drive would be needed in any case.
Search this data base on the word "Ketch" for more info.
Below is a previouse posting I submited.
Last summer I purchased a 1977 CD30 ketch, hull #36. Have enjoyed it every weekend since. Ketch or cutter? Good question. The cutter rig appears to be more popular. All the later year boats are cutters. All the listings I have seen for ketches are either 77's or 78's. Note that the hull is the same for either rig. The interior varies a bit by year, but not by rig. I purchased a ketch because of opportunity, cost, and timing. I liked the idea of a ketch rig, but was concerned that it might be a bit crowded in a 30 ft boat.
I can seat five comfortably in the cockpit, seven with some crowding. Without the mizzen mast I could probably fit one or two more. The mizzen mast and boom turn out to be good cockpit handholds in rough weather. The mast is just right as a handhold when coming up from the cabin. The mizzen shrouds and main split backstay are a little busy, but again provide good handholds. I have a cockpit awning that goes over the mizzen boom and provides good rain and sun protection, if the mizzen is down. On my to-do list is to build an awning to be used while flying the mizzen.
The main mast is farther forward on the ketch rig (2 ft ?). This allows me to store my 8' 6" dinghy on the cabin top for offshore work. I don't belive you could do this with the cutter rig. The main boom does not extend over the cockpit as it does on the cutter, which is a saftey plus in case of an accidental jib.
Handling of the mizzen sail is a snap. In addition to the standard sails, a mizzen staysail and mizzen spinnaker could be flown from the ketch, if you really want to stay busy. Here are the comparison working sail sizes for the cutter and ketch:
Cutter: Fore Triangle 232, Main 205, Total 437
Ketch: Fore Triangle 207, Main 165, Mizzen 66.5, Total 438.5
I final point in favor of the ketch is that it is a blow against the humdrum skyline of single masted, sloop rigged, plastic boats seen on most sailing days and at most marinas. I bow to others to highlight the benefits of the cutter rig.
