radar on the mast

[asdf777]

I've been wondering how having a radar on the mast affects rolling... Is it possible to calculate the effect of additional weight on the mast in calm and storm conditions?



Displacement = 8,600 lbs official, 9,600 lbs real.
Ballast: 3600 lbs, lead.

Mast height above deck: 37.5 ft
Radar height above deck: 22 ft

Radar weight with mount bracket: 30 lbs

Many thanks!
