However much planning you do...
This from Vivian at Catana:
The engine servicing has been finished this afternoon. The mechanics from VOLVO could test both engines and they discovered a serious problem on starboard. The turbo is not working properly as the variable pitch command doesn’t work anymore. It is very corroded as well as the exhaust manifold. They will send us a quote asap.
If they order the parts today then they should arrive on Wednesday and we should still be on schedule to complete all the work by the end of the week. Fingers crossed.
