Sailmonkey is correct .

The pipe is for pressure testing the rudder. All sealed areas are pressure tested to ensure there are no nasty surprises later.

Unlike fibreglass rudders, the shaft can be welded onto aluminium rudders. This permanently seals the opening. Fibreglass rudders invariably develop a leak where the shaft enters the top of the rudder. If the rudder fills with water this adds unwanted weight to the stern and creates concern about hidden deterioration of the the interior components.

Rudders on plastic boats are ALWAYS full of water

Yet another reason to love metal boats. The list just keeps getting longer . . .

Interesting that your rudder is left empty. I guess one of the benefits of Alloy over Steel.

All the steel rudders I have serviced, including Stargazer, were filled with light oil or diesel.
I guess that is to provide anticorrosion protection on steel.

Never thought before about the pros and cons of leaving the rudder empty....

Thinking out loud:

I don't think the weight is an issue.
Would the harmonics of an empty space create more stress?
Filled with fluid, it would be close to neutral buoyancy allowing easier removal in water.
I like the idea of oil indicating damage if your rudder hit something at sea.

I know the yard will pressure test, but maybe they also put some fluid inside??

thanks for the explanation.

More please

more aluminum mmmmmm delicious aluminum

Perhaps they can turn on a webcam AFTER the employees leave? NSA monitoring them regardless . . .

The next batch of photos arrived yesterday .
I see several of you have been impatient to see more photos, so you can just imagine how we feel .

We have been flat out this last week going over the first full 3D file of the interior. The drawing apps on the iPad combined with an Apple pencil have been extremely useful. The process has been to describe the changes, take an image of the lap top computer screen for that particular area, add drawings and notes to the image with the Apple pencil and then attach all that to an email. A slow process, but it instantly illustrates what changes need to be made, so hopefully this will save time at KM's end trying to interpret written text.

This morning the last email was sent with the bulk of the comments made so I can take a little break while waiting for the revised files to arrive and indulge in looking at the new photos .

The cabin top going on was just a dress rehearsal. It is back off while more welding is being done.

The standpipes are in. We have these now on our current aluminium boat as well and they are the best solution. These three are the ones for salt water inlet for the galley, sink drain and grey water tank drain. They end above the waterline, but Marlon seacocks will be fitted to each:

The day tank is in as well, just to the rear of the watertight engine bay. An impressive inspection hatch is on one side. The fuel level will be visible, plus it will have an inlet on the top for emergency manual top up of fuel:

SLICK city.... I loves me some dedicated standpipes...

If you feel overwhelmed and need somebody to review details and make necessary changes to the guest berthing accommodations... I'd be happy to help....

I think if I left that in your hands the size would triple .

The guest area may be a bit skimpy by some standards, but the worshop isn't .

The heart of the boat is situated adjacent to the engine bay. A 2.6 m long L-shaped aluminium workbench will go along the starboard hull. The removable "5 tread" alu plate floor seen below all belongs in this area. The current workshop we have is in a similar position and invaluable when cruising long term.

The watertight bulkhead at the rear of it separates the living quarters from the "garage" (I refuse to call it a lazarette now that I know how the name originated ).

I love the extra care and trouble taken with small details - check out how the frame has also been covered in 5 tread where it intersects with the floor:

This photo gives some indication of the strength of aluminum construction. The area of the hull close to the back of the keel is a spot where there is often damage from hard groundings. The bottom is forced up as the keel strikes. The stuff of nightmares! Here you can see as well as a deep centreline keelson, there are numerous deep transverse frames. Also, the hull plating is an impressive 10 mm thick in this area. Compare this to a production fibreglass boat with a glued hull liner:

Seaworthy Lass, what is the assembly at the forefront of the picture? The transverse bar with round structure at each end.
