Hi. I wonder if someone could help me with information about Catalac hull construction.
I have a 9 m Catalac with twin diesels and saildrives. Just beside the saildrive on the bottom of each hull there is a wedge shaped construction. I assume it is intended for exit of straight propeller shafts. It is about 50 cm long and 20 cm deep in the aft end. As I have saildrives I donít need these and expect they create unnecessary drag. Does anybody know if this is a normal Catalac 9 m construction? Are they only external additions that can be removed, without revealing holes or weaker parts of the hull behind? They do not show from the inside.
