Here’s a sample project from Jamie Morrison, NS30U 225 Dexterity II:
Masthead Sheave Replacement
Here’s the masthead casting and original sheave and shaft. Some castings have two sheaves but most are like my single sheave casting.
Here’s the masthead casting removed. It took a bit of work to get the stainless machine bolts out of the aluminum casting but with a little penetrating oil and some heat they all came out without any issues.

Here’s a photo of the old sheave and shaft and you can see the scoring on the sheave indicating it had been binding against the masthead casting.
The entire project took only a few hours. I did it with the mast removed from the boat and that made things a lot easier. I also took the opportunity to tidy up a few other things at the top of the mast and make a few other minor changes. The next spring when I installed the mast the sail went up as easily as can be and better still it dropped like a rock when it was time to put the sail away. Ten seasons have passed since I did this project and the sail still goes up easily with no signs of binding. I regularly lubricate the sail track and clean the sail slides.
Here’s some terrific projects from our Rendezvous co-chair Chris Oullette, NS30U Felina.
It’s been a long winter here in Nova Scotia and Chris has been very busy with some simply stunning boat projects.

Here’s another project from Jamie Morrison, NS30U Dexterity II
Transom Mounted Davits
I originally had a set of Atkins & Hoyle davits that were deck mounted on the stern. After I was struck by another boat my dinghy and davits both required replacement. I purchased a new set of davits from Atkins and Hoyle, which are now built heavier than the original set, and I also purchased a new dinghy. The dinghy had a bit more beam than the old one so I decided to move the davits out to the transom so they would extend a bit further to accommodate the beam of the new dinghy. Previously the deck mounted davits were limited in there reach by the pushpit.
The photo shows the davits partially installed. I am about to install Dyneema stays from the top of the davits to the coaming to provide extra stability as instructed by Atkins & Hoyle. I should note that this installation required epoxying a piece of ¾” plywood measuring 10″ x 20″ behind each davit to stiffen the transom. There is also a 6″ x 9″ x .5″ aluminum backing plate on top of the plywood. Each davit is capable of holding 350 pounds. My dinghy with motor weighs 247 pounds.
