17/05/2013 – Transom Paint
Sanding the transom ready for a repaint. Started to sand the paint off down to the gel-coat with 400grit wet and dry. The gelcoat is in great condition with only a few minor areas that will need filling. Next step after the sanding is paint. A good red paint is going back on when the weather is right.

25/03/2012 – Rigging Tension
Rig tension is more of an art than a science. If you ask ten people advice on the subject you are likely to get ten different answers and five of those answers won’t apply to an in-line rig! So to apply some science to the solution a Finite Element (FEA) model of the mast and rigging was developed. The theory showed that setting mast tension is still mainly an art. But, what the model can do is look at non-linear buckling and of the mast section, this shows the importance of check stays and the restraining effect of the sail.
25/03/2012 – New Standing Rigging
During the last sailing outing I heard a loud twang, when on a broad reach. An inspection of the rigging found one of the wires on the caps stays had ruptured due to corrosion. The current rigging is high-modulus (stiffness) dyform. As planned I took the mast down for a survey and found the dyform had patches of corrosion every 100mm. This type of corrosion is not uncommon for stainless steel if it has been cold worked such as the dyfom manufacturing process that consolidates the wires. Nothing a trip to the boat shop wouldn’t fix. Binks were able to help and suggested using Hamma, this wire has the same high modulus as the original rigging. The mast was in very good condition, mostly due the previous owners respect for galvanic corrosion and his use of Duralac, insulating washers and sleeves on dissimilar metals.
19/03/2012 – Sailing Begins
After a great deal of work the motor is now operational, the yanmar 1gm10 has proven to be an excellent choice for the boat as it runs extremely well. There have been many sailing outings but I have done this with reduced sail area until we get the mast down for a survey. The mast is fine but I need to replace the runners, backstay and while it is down I will also replace the shrouds.
