Design 2159 Sumbra III

Sumbra III is a very typical One-Tonner design from the period. She was built of wood using cold molded techniques by Cantiere Sangermani of Italy and launched in 1973. The design utilized the Lines, Construction and General Arrangement plans from design #2094. If you recall this was a speculative design that was used numerous times, such as the boat Lightnin, design #2094-C1.

Here is the Deck plan. The style of this drawing is interesting and was commonly done. Only the starboard sheer line is drawn since in the draftsmans mind the boat is symmetrical, so why draw it?


The ballast keel was also modified from #2094. Heres the Ballast Keel plan.
