I installed tacktick on my yacht when I purchased it mainly so I didnt have to run a wire through the mast
When the system did work there was a noticeable delay in the display with regard to wind
shift. The system regularly cut out for no apparent reason, this may be because the yacht was 52ft with a tall mast
and they only recommend up to about 35ft I think, the seller omitted to make me aware of that.
I put up with the numbers blanking out routinely usually when navigating an unfamiliar passage
or reef then one day it blanked permanently while the spinnaker
was having trouble staying filled, the mast head
transducer had fallen off. When I brought it to the attention of Tacktick that there was no screw or even glue attaching the wand to the base they said the new ones had been fitted with a screw but I still had to pay for a replacement (not cheap)
The new masthead sensors have an improved signal beam so should work better I was told, it still blanked out and now took the depth
reading with it.
I also found out recently while sailing in rain squalls that the wind
display quits completely for extended periods, I sent the new masthead sensor back to be checked and Tacktick returned it saying it was fine and that they do not work in heavy rain,
thats reassuring isnt it.
Anyway I had the mast out recently and fitted a wired wind instrument and now in the process of fitting a different depth
instrument also so I wouldnt be recommending tacktick.
Good luck, Niv.
