Design 1761 - Sumbra


Here's another beauty from Cantiere Sangermani of Lavagna, Italy. Sumbra was designed to rate under the R.O.R.C. Rule. She is a big, powerful, ocean racing sloop. Note the coffee grinder on the aft deck.

The boat is constructed of wood using Iroko for longitudinal structural members, Movinguo and Acacia for transverse frames (laminated) and double planked in mahogany. Fasteners are of Silicon Bronze.

Many Sangermani boats can be found in these pages. Simply use the search engine within the blog to find them.

Here are the plans.

These two designs are 70 years apart (design #125 designed in 1935 and design #2723 designed in 2005) but in this subdued lighting the family resemblance is clearly evident. Thanks very much for sending the image.

Design 990 - Rogue

Newport 29 - Rogue
Image Courtesy Ben Mendlowitz

This boat has an interesting provenance. She is a Newport 29 Class designed by N. G. Herreshoff but built by Seth Persson of Saybrook, Connecticut and launched in 1953. Sparkman & Stephens was hired to modernize the rig and deck layout, the result of which you can see in the plans below. She was assigned job number 990. In addition to the sail and deck plans you see here we produced drawings for the spars and all rigging details.

There is plenty of material about her on the Internet as she is still actively sailed in and around Newport, Rhode Island. Note she is configured as a yawl in the image above so somewhere along the way she was modified from these plans.

Design 1197 - Windbourne II


The more I study this design the more I am impressed. I could be perfectly happy with this for a cruising boat. Windbourne II was built by Paul Molich of Denmark, a top notch builder. She is constructed of wood and launched in 1956.

Here's a project that never got off the ground. Commissioned by an Argentinian businessman to be a "smaller version of a Tartan 10", these preliminary plans were drawn up and some fancy brochures were printed. Beyond that I have no idea...

Design 58 - Werdna


I found a great list in our files earlier today where someone had taken the time to weed through all of our design numbers and separate the "not built" designs from the actual projects, in longhand no less. I mean I have been doing so slowly through the research for this blog but here was a nice concise list of boats. In taking a cursory look I noticed design #58 immediately as another one of our designs that has flown "under the radar".

Werdna was built in 1935 by Albert Lemos of Riverside, Rhode Island. It's a good study in an early S&S rig type that was abandoned pretty quickly: bow sprit and boomkin, for later, higher aspect ratio rigs. Note the lashed rigging terminations at the top of the masts versus the metal tangs that were in place very early in the designs to come (as well as elliptical spar sections).
