Hello,

Like Fred wrote, you cannot compare Furie 99ft long, and Wattle 75, so the displacement of the latter is only 40 to 45% of Furie, and the maximum speed of Furie is 8 kts (being designed in 1912 as a tug), while Wattle speed would be 10 kts, indicating very different propulsive designs. Thereby, there is no standard 100 RPM.

Nonetheless, as up to now the only known data come from Furie's crew and shipyard, your data about the accelerations of this tug will be greatly welcomed, I am sure, as a point of comparison. Any data about displacement and ihp?

Regards,

Luc
