Three’s company
NANNI Diesel's N3.21 is a prime example of how adding another cylinder can gain significant torque and power gains for little extra weight. Compared to its N2.14 counterpart, it is only 15 per cent heavier but produces 57% more torque and 50% more power.
The additional torque is the big plus, enabling this engine to provide more than adequate power for larger traditional cruising yachts like the Clansman 30. From 1966 to 1985, 105 of these full keel yachts were built by Fairlite Plastics/East Coast Yachts, the same company that built my lovely little 3.8 metre Fairlite Gull sailing dinghy.
The Clansman displaced 4.1 tonnes in light ship form, 26% above the way more popular
