The reason I am pursuing this is there will be others coming behind me and they can make their own minds up.
The aft view of the Nautitech 47 shows that on the starboard tack at least there is completely clean air. Colemj states that the boat won't go to windward on this tack - why not?
Colemj states that at best on port tack a broad reach only is possible. I maintain that you will get clean air up to a beam reach and accept that there will be disturbed air going to windward on port tack.
Upon further research
there are Hydrovanes fitted to a Lagoon 380
, Lagoon 400
410 and a St Francis 50 amongst others.
have addressed the problem of bulky superstructures on cats by doing two things. One, the gear
has to be on the extreme end of one of the pontoons and two, specify the fitting of an "extended heading tube" which jacks up the height of the vane by another couple of feet or so. Note that the Nautitech 47 in the picture does not
have this fitted and could be added if needed.
A direct comparison between the height above waterline of a Nautitech 47 and a Lagoon 440
cannot be found on the internet
. By inference, if it's okay for a Lagoon 400
and 410 then it's okay for a 440. I'm only trying to be rational here.
