Oops, I also need to answer the question from Easy Rider. Almost any boat can be electrified - they are even now building electric Washington State Ferries. The critical factor in deciding is how you plan to use your boat and how much are you willing to spend. If you are willing to travel at...

comparison of my dory to Gerr\'s equation

I agree with Thataway that the hull speed equation is only an approximation. I have used Dave Gerr's book a lot and found that is equations and numbers are approximations, BUT most of the results when actual measurement are made with real boats are about +- 15% of the calculated values. I have...

Good point. You note that your hull speed is about 4.3 mph because the bow starts to climb the bow wave at that time. I have no problem believing that because the weight distribution is optimized to get the boat on a plane as soon as possible. The sooner the bow starts to climb the bow wave...

Bob with Thataway has asked me, on another thread, for some cost numbers for the electric conversion I am doing on a C-Dory 22 cruiser. Since this has nothing to do fixing balsa core, I decided to start a new topic. My initial estimate is that the cruising weight of the 22 ft cruiser will be...

To answer the question from Thataway - I expect that my C-dory will be finished sometime by the end of the month. After that I will need to spend some time altering the cabin to add a second berth under the helm seat. NMI is building the starboard side of the cabin with the platform running...

I now have posted two pictures on the C-Dory being built for me (can be viewed under my name since I don't have an official name for the boat yet). These were taken when the top and bottom were put together three weeks ago. The completion date for the boat is now towards the end of March. I...

This is an interesting and long running thread. However, I did not see any mention of first trying to find out how the water got into the balsa. Were there cracks in the outside of the laminate or did the moisture come in from the deck? If the moisture is coming from a crack (however small) in...

Have you considered pressure treated wood? It is not pretty, but since you will be covering it with fiberglass, that should not be an issue. Another option might be to use square aluminum tubing ( https://www.onlinemetals.com/en/buy/aluminum-pipe ) and attach the cabinets with self tapping...

King Marine Canvas in Seattle (Ballard) currently makes camper tops for the C-Dory 22. They have a lot of experience with C-Dories. You might want to check with them to see if your canvas is one of theirs. If so, they have all the measurements for the frames.

A lot of questions are coming up and I will try to answer some of them. The current version of the C-Dory 22 cruiser has the interior sections molded in several pieces. NMI is using a honeycombed glass composite (1/2" or so in thickness) for the interior. The port side has the table and two...

The current version of the C-Dory 22 cruiser does not have bench seats on either side. Port side has a dinette set that can be converted to a berth and starboard side has the helm seat and raised work space for a sink and/or stove. All NMI will be doing for us is extending the 9" platform that...

Yes, everyone. This electric C-Dory they announced is my boat. I just visited the shop this morning and they were just starting to spray the gel coat into the mold. Estimated time of completion is early March. I am having some modifications made to the cabin. The starboard side sink etc. is...

I had my King trailer for 15 years and the reason I had to replace it was that I found that the steel beams were beginning to show metal fatigue. This is something no one has mentioned yet. The symptoms were increased "bouncing" as I went over bumps and a slight deformation in the main beams...

I would suggest getting in touch with Michael at Northwest Marine Industries, the guys who now make C-dories. They arrange with Ez-loader for new trailers for all the boats they build (including the 25 ft. cruiser). I am having a 22ft cruiser built and they are charging me $7200 for a...

Sam Devlin has built two solar electric boats (approx. 30' and 50') that come regularly to the Port Townsend Wooden Boat Festival. These are powered by pod motors. The owner of the 30 footer told me that he was inspired to have Sam build him one after seeing my electric St. Pierre Dory at...
