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 draftsman's mind the boat is symmetrical, so why draw it?


The ballast keel was also modified from #2094. Here's the Ballast Keel plan.


Principal Dimensions
LOA 38'-6"
LWL 28'-9"
Beam 11'-9"
Draft 6'-3"
Displacement 15,309 lbs
Ballast 8,000 lbs
Sail Area 604 sq ft
