Thanks for the note. I do not know who supplies Nauticat with the fairleads.
The best contact at the Yard for information is Veli Karja. his contact email is ”email@example.com”. He may take a couple of days to come back to you. I have found him very helpful when after technical help in the past. As have a very large number of other owners both in UK and around the world.
You will need to quote in your mail; type of Nauticat, your boats hull number (usually on the stern) and year of build. Plus send them a few photos of the parts / area that you are after. I have found this helps.
The Yard keep a full record of each yacht they have built. So they can dig down into the original build spec of your boat if needed.
Have you had a look around the “Technical Library/Data” which our technical expert Alan Worrell looks after. There is an oldish list of suppliers in there somewhere. If you have specific issues then do send Alan an email. His contact details are in the directory section. Alan also has a Nc35 so he may know the details.
Hope this helps
