5: Winter 2016-17: Reassembling

A few pictures that Simon took as he put Serina back together. Here is the centre-plate at the pivot point.


The picture below is taken looking down into the centre-plate well. The cylinder is at the top of the picture, running down until its jaws attach to the trailing edge of the centre-plate. The jaws can just be seen before the daylight visible under Serina.img_0342-jpg

Simon took the picture below while standing in Serina’s cuddy. He is facing the stern and looking down into the centre-plate well. The fiber-glass “box” that normally protects the bottle-screw, and prevents water entering the cockpit, has been removed to enable disassembly and re-assembly.img_0339-jpg

The next photo is taken at the level of the cockpit floor, looking back towards Serina’s cuddy.img_0340-jpg

The pictures below show the cylinder attaching to the back of the centre-plate – which is in the raised position. In the left hand picture you can glimpse the pin holding the jaws of the cylinder to the back of the plate.


7: Winter 2016-17: The unexpected mast repair

On the day before Serina was due to be launched, Simon noticed a crack in the mainmast.img_4103

He was curious and flaked-off some more paint to investigate. This is what he found:


This looked like a crack in the carbon-fibre so he carried on investigating:


This appears to be a seam between two pieces of carbon-fibre, that hadn’t been filled properly when first made. Notice the top and bottom of the gap appear to be filled.

We think the crack in the paint may have happened during a windy sail last summer. I’m glad I didn’t notice the mast bending at the time!

Anyway, Simon patched-over the gap:


Rubbed it down:


And painted it:


And Serina was launched on time.


6: Winter 2016-17: The mast bands

The last of the planned work this year was on the masts.

Last year Simon Beaven fitted these beautiful stainless steel mast bands to carry the halyard blocks. However, I still managed to scratch the masts with the blocks attached to the spar. The same issue affected the main mast and the mizzen.



So, after lots of discussion, I decided to ask Simon from Quayside Marine to fit some protective sleeves to each mast. Simon again worked with Stephen Lord (from Flux Fabrication and Welding) to create a sleeve for each mast – to protect them from the blocks.

The new main mast and sleeve is shown below. The sleeve is made from a thin (1 mm) sheet of 316 stainless steel, rolled and welded by Stephen into a tapered tube that slips onto the mast.

I’m sure purists would be worried about the additional weight aloft, but I think I’ll appreciate the absence of scarred paintwork more than I’ll be worried by any minor increase in instability.


And here is the mizzen:img_4121

And the two together:


And here is Serina back afloat with her new sleeves.

4: Winter 2016-17: The centre-plate

Apart from the work on the “stump” and bottle-screw, Serina also needed a fair bit of work on her centre-plate.

As far as I am aware, this winter is the first time that Serina’s centre-plate has been removed in 10 years and this is what it looked like.



Simon ground off the rust and treated it with a rust-preventer before priming:img_3925

epoxying – 4 times.img_3961

Followed by a rub-down and undercoating

and painting again.


Isn’t that beautiful?

3: Winter 2016-17: The centre-plate winch solution

The first task Simon performed was to repair the “stump” by building-up some new glass-fibre.


He then attached a protective cap onto the stump, which should prevent damage in future.

This cap was beautifully made by one of the local Lymington craftsmen (Stephen Lord of Flux Fabrication and Welding) and is made of 316 stainless steel. It should stand-up well to the salt and damp of the marine environment and not wear as quickly as the previous arrangement.

Here’s how it looks when all reassembled.

2: Winter 2016-17: The centre-plate winch

The big difference between the UK- and Dutch-built Romilly boats is that the UK-built boats use a strap to raise the centre-plate, operated via a winch mounted in the cockpit. (See David Collin’s description of a UK-built Romilly here.)

The Van Veen boats use what I’ll describe as a “bottle-screw” mechanism situated in the cuddy.

Here’s a picture of Serina’s cuddy, just showing the winch socket in the centre. Note the absence of winding mechanism in the cockpit.

I’ve included a few other photos to give an idea of the winding mechanism.The photo above shows the reason behind this winter’s work.

I didn’t like the look of the cracks in the fiberglass “stump”, nor the way the black terylene washer was biting into it.

It’s also time to show what I mean by “bottle-screw”.

Instead of the strap used to raise the plate on UK boats, Serina┬áhas a solid bolt that screws into a threaded “cylinder”. The lower end of the cylinder is attached to the trailing edge of the centre-plate. As the bolt turns, it gets pulled into the cylinder and, in turn, the cylinder raises the centre-plate.

Here’s what it looks like when partially disassembled:img_3829

The wear to the “stump” is clear, as is the build-up of dirt on the bottle-screw.

Just one more picture to help orientation.

Here is a photo looking up inside Serina’s┬ácentre-plate housing:

Here’s what it looks like when dismantled. The cylinder I mentioned earlier is show below, with the screw below it. The winch socket is also shown on the right. It is held onto the bottle-screw via a cotter-pin that can just be seen in the winch socket.


And once Simon had cleaned it up it looked beautiful again!


The cylinder is shown above – and the jaws on the right fit over the trailing edge of the centre-plate.

The the jaws of bottle-screw (below left) attach to the centre-plate via a pin and a grub-screw below.

The pin fits through the jaws at the lower end of the cylinder, and the grub screw threads into both to hold them together.

And if none of that makes sense, perhaps a picture will help.
