Stikhedonia (formally named Selah) had three foot extensions added to the transoms. This was similar to a modification that many Seawind 1000 owners completed on their catamarans before the Seawind 1000XL was offered.

Hi
I am considering extending my catamaran from 12 to 13 meter.
Did you experience any difference in boat speed and motion after your conversion?
Many thanks
Peter, I felt it helped with motion and speed. When sailing next to other 1160s I would estimate a 0.5 to 1 knot advantage as there is almost no wake with my extensions.
