Seakeeper usually unveils new stabilizer models for yachts that previous models don't cover. The Seakeeper 6 is different in that respect; it's for 40- to 49-foot hulls, the same as the Seakeeper 5, but with upgrades.
“Though the Seakeeper 6 offers 20 percent more stabilizing force than the Seakeeper 5, it takes up less space and is more efficient in terms of weight, power draw and cost,” says COO Andrew Semprevivo.
It also works faster. The Seakeeper 5’s spool-up to stabilization time is 35 minutes, while the Seakeeper 6 reportedly takes 24 minutes. In rough seas, that’s a lot of belly-saving time.
