Hi James, I have a 34/36 and I did replace the sensor twice.. Once with the mast off and once "in-situ"/
My mast did have a conduit and I used the old wire as a messenger line as mentioned before. Really straightforward / no issues. The harder part is that I had to fabricate a custom aluminum bracket to accommodate the new sensor and mount it solidly. I was glad I had the mast off as it took a lot of measuring / fitting / trimming to make sure that the bracket was as long / wide as possible to spread the load / fit in the mounting holes / not interfere with the halyards and sheaves / VHF antenna mount / tricolor. Also, while the mast was off I did a fair amount of cleanup / refreshed the spreader boots / replaced deck light bulbs / etc. Long story short it was 80 bucks more than well spent to take the mast down / get it all done right / clean, lube, easily service everything I could while it was down. The 2nd time I replaced it (It appeared to have been nailed by lightning surge). That was "in-situ" but then all the hard stuff was already done it was plug and play. My 2 cents. -Francois Rivard 1990 34+ "Take Five" Lake Lanier, GA 34-36R with a pretty skinny tall mast?anybody have any experience upgrading the wind sensor and VHF while the mast is in-place? I need to know if there?s a conduit running and what to expect as I may be the person scaling the mast and I want to make the least number of trips to the top? And?if somebody?s done this, what where the learning moments? Thanks. James. Bibb SV Darwin?s Folly C&C 34-36R
