2062 C1 Sunbird II

As far as we can tell, the Endo Corporation of Japan was a 6-time repeat client, ordering 1/4, 1/2 and 1-tonner racing yachts in the early 1970s. Most of not all were built by the Kato Boat Company of Yokosuka City, Japan in either wood or fiberglass. Here we have the one-tonner Sunbird II. She was built of wood and launched in 1970. She is based on a very well utilized design, #2062, but with modifications (optimizations) to her rig, keel and rudder.


Heres a look at her shape.

Design 1780 C1 Satanita

Satanita is a sister to the famous Firebrand, design #1780. She was built by Keith Atkinson of Auckland and launched in 1965. Looking at the plan list it appears the only change was the reverse transom, whereas later boats built to this design benefited from a separate rudder. The above image is a newspaper clipping, and is the only image we have of her.

It is interesting that later sisters of this design benefited form a separate skeg and rudder. The former owner of Satanita sent us the image shown below which looks to me like someone added a separate skeg and rudder, removed the old rudder, while maintaining the original keel profile.  Thanks for sending this image.

According to that owner:  When I bought Satanita there had been a crude,(in terms of design) modification whereby the rudder had been removed but the full keel profile left. A small rudder on a skeg had been fitted only a short distance from the keel. This appeared to have increased the wetted surface and the boat was totally unmanageable in reverse.

Heres a shot of the original keel and rudder configuration on Firebrand.

By following the link to the posting regarding Firebrand one can see the S&S revised keel profile, skeg and rudder at the bottom of the article (general arrangement and inboard profile for C4).

While we are on the subject of Firebrand, heres a letter we unearthed from her original owner to her then new owner describing her sailing characteristics.  Its an interesting read.  Please simply double click for zoom.

Design 1998 C1 Alpa A42

This past weekend we posted an article about design #1998, a boat named Dida II. She was the prototype for the boat you see here which is described in all of our records as a "motorsailer". Its a bit hard to believe that these boats came from the same tooling as Dida II as the boats are just so different but apparently someone felt a motorsailer model would be a good seller.

Clearly only the hull mold was used. It was a fairly common trick to add headroom by adding a vertical component to the deck above the original sheer and thats just what was done here. That did allow them to add some hull ports which must have made the accommodations much brighter. Alpa used this trick in their other models such as the Alpa 36, design #2172, Alpa 21, design #2204, Alpa A27, design #2241 and the Alpa A34, design #2242.

Here are our own concise designers comments from the time.


The production run began in 1973 and 8 boats were built to the design.

Heres the company brochure.


Here are the plans.

And heres a shot from the Genoa Boat Show of 1973 which gives a great view of her deck layout.

Design 2207 C1 Nauticat 521

Here we have another Nauticat motorsailer model that was based on a previous model by Nautors Swan, design #2207. She is a heavily built motorsailer of similar proportions to the other Nauticat models. Ten boats were delivered during a production run that started in 1989 and lasted two years. The boats were built by Siltala Yachts of Finland.

Design 1674 C1 Sunward 48

Weve made mention of this design before. The original boat was named Toc Toc and was built of steel. The boat was eventually developed into a production fiberglass boat that was built and marketed by Marlow Yachts of Deer Park, New York and called the Marlow 48. This was around 1970. From there the molds were purchased by Bennett Brothers Yachts of Wilmington, North Carolina. The model was renamed the Sunward 48. What you see here pertains to the Sunward 48.

Here are the plans.


And here is the most famous of all Sunward 48 owners, Walter Cronkite, aboard his boat Wyntje.

Design 1701 C1 Weekender

We have previously posted an article about the Rainbow Class, design #1701.  Here we have a modified version, called the Weekender and also classified as a MORC racer.  Heres the brochure.

Aside from the addition of the fairly rudimentary "cruising" interior, the modification was fairly simple and included a blister on the coach roof as can be seen in the excerpt from the construction plan, and a heavier keel.

The boats were produced by Tidewater Boats of Annapolis, Maryland.  We can see that the base price of a Rainbow in 64 was $2,695 and the Weekender model was $3,395, a $700 option.
