Can anyone explain what the function is of the notch and ring on the top of the rudder blade? There is nothing attached to while sailing. Is it perhaps used to secure the blade when having to remove the pivoting bold?

The notch coincides with a hole in the stainless steel rudder stock and allows a pin to be put through, trapping the rudder in the full down position. This is good in that it removes reliance on the cam cleat (ours has let go occasionally) but you would have to remember to remove the pin when in shallow waters. Our notch does not have a fitting in it.

Thank you Ewan. However, our rudder stock doesn’t have a hole I think.

It's the small hole just below the push-rod bracket. I think I see it in your photo.

Notch in Rudder

Hi

When I acquired "Sulito" 325 it had a metal bolt that would slot into the notch

However Pascal (From Paimpol France, Maruli 325) suggested at the time that if you grounded hard you would either damage the rudder or the rudder stock. He used a wooden dowel (8mm) which in the event of grounding the rudder hard, the dowel will break and so protect the rudder and stock

I brought a length of 8mm round dowel from B&Q and cut several sacrificial lengths, just pine nothing special

I put a small hole in one end and tie on the back rail, works a treat. I am still on the original dowel 5 years later

But it does hold the rudder from popping up and if moving into shallow water you can release the cleat and the wooden dowel will hold the rudder in place. A very sensible option, we can thank Pascal for his idea

Regards

Barry Tiernan

That’s a very good idea. I will also buy a length of 8mm dowel and remove the current clamp from the top of the rudder blade.

I already wondered how to keep the blade down while releasing the rudder downhaul in shallow water. I already had situations where I lifted the keel to a level where the rudder blade must have must have been the lowest point (about 1.20m). Fortunately the blade never touched a hard bottom so far.

I tried the suggestion to place a 8mm dowel through the hole in the rudder stock and the notch in the head of the rudder blade. However on Surprise these do not line up nicely. The only way to put a dowel in is to reame the notch by drilling a hole through the existing hole.

Hi Dirk

I can see your difficulity. Cant explain the difference. I must look at another 325 in our club to see if it is different. I presume the rudder is fully dowm, Mine is approx 1.4 m when fully down

regards

Barry (Sulito)

Yes, the rudder of Surprise was fully down at the picture. From one of the photos of my rudder it looks like the hole of the central bolt was perhaps not exactly in the center of the rubber insert in the rudder blade

I will think about drilling a hole to fit a dowel and finish the top of the rudder blade with an epoxy coat to prevent ingress of water
