Thanks for your reply. It helps a bit...Still I don't seem to be able to make a good decission...
My main questions at this moment:
- Will there be a gap between the Ultrasonic and my Futura 111?
- How good will the combination of 8.7H2 with the Ultrasonic be and will it be a better combination than the 8.7H2 with the Futura 131?
- Is it possible and comfortable to sail the Ultrasonic with my 7.7H2 also (in low powered condition where it's not nice to sail with the 7.7 on the Futura 111?
I don't expect to be on the water below 10/11knts. All opinions are welcome.
