We are planning a new chartplotter on Molia to be positioned at the helm station.
We are looking at the Raymarine Element Series (not too expensive) which has physical buttons. In my opinion a touch screen at the helm station in UK weather and sea conditions could be problematic!
The S7 is small enough to fit into a rail-mounted pod. We have limited space at the helm station on Molia, so we checked out the Scanstruct Rail Mount SPR-8-RM which can sit on top of our existing wheel guard rail.
To try this out, I made a cardboard mock-up of the rail pod. We wanted to check that the unit will be comfortably visible sitting at the helm. Here is Jo holding the mock-up in place; looks OK!
We are replacing the entire holding tank discharge seacock assembly with new DZR fittings.

I ground off the old skin fitting from the outside using a cordless angle grinder – there was no way any of the old seacock was going to come apart!
Once the old brass was all ground away, the old seacock lifted out easily. I cleaned all the old sealant from around the hole with multi solve.
Next – and this is important, I dry assembled the new brassware. It was at this point that I discovered I had missed an elbow joint when I made my original order! The assembly has to wiggle past Molia’s fuel tank. ASAP Supplies to the rescue again! – I had a second elbow in 24 hours – top job.

Attached the new skin fitting today – leaving it to dry before doing anything else.

Once I had all the parts, I put them together one at a time with the Loctite 572 in the shape that I had practised during the dry assembly.

I did also take the opportunity, while the locker woodwork was removed, to give it all a new coat of varnish back at the workshop.

With the new seacock assembled, the next step was to fit the new hoses to the top and bottom of the holding tank. This is not an easy job! The 2 inch hose is very stiff and fits tightly between the deck, tank and the new seacock.
I replaced the old webbing strap (which had rust stains) and its plastic buckles and bridges with stainless steel.
The new fittings are from GS Products, and are really smart – although in the end you cannot see the bridges as they end up behind the tank and also behind the plywood front panel.
Lastly, a shout out to Chris of the ‘Sailing Britaly’ blog on YouTube for his excellent recommendations and guidance on this task. This video teaches you everything I have mentioned above, and includes lots more good advice as well.
We have a Lewmar folding wheel – this is a special edition manufactured for Dufour of the Lewmar 40inch folding wheel. This is great invention for a smaller yacht like Molia – it means we can get around the helm easily when moored.
Removing the wheel is not that easy when it has been in place for several years. However, the procedure described in this YouTube video works well.
Remove the centre cover and remove the nut and washer from the spindle.
Remove the autopilot clamps from the wheel spokes.
Put the nut back on the spindle (without the washer) so it is sticking out just past the threads.
Exert some even pressure behind the wheel with your arms and leg.
Hit the nut a few sharp taps with a hammer, and the wheel should pop out against the nut.
We have a Raymarine ST4000+ (aka Mark 2) autopilot on Molia. This was not working reliably last season.
To get to the autopilot, I first had to remove the wheel. Once the wheel is off, the autopilot wheel drive unit unplugs.
The instructions say to replace the drive belt if is damaged.
Having removed the support plate from over the clutch rollers (2 screws), I saw that our belt had a loose string, and there was lots of fluff in the drive! Time for a new belt…
These are looking old and dirty, and one of the covers has perished and no longer attaches. We were unable to clean the plastic surrounds, so a complete replacement is necessary.
We have found replacements for these covers, and they are on order.
Our survey highlighted the rusty and damaged state of the sanitary hoses on Molia. We will replace these all as part of our winter maintenance.
Also, it has not been possible to move the seacock for the waste holding tank discharge this season, it is probable that this will have to be replaced.
The toilet discharge sanitary hose and seacock are on the right in the photos above. Having removed the old hose I was able to ease the seacock considerably, and lubricate it. The replacement hose is 38mm sanitary hose (this length 2090mm). The jubilee clips are new 30-50mm diameter A4 stainless.
I cut the old hoses (with a saw) and removed the holding tank to get to the connections. These were completely seized on; so I had to cut through the hose carefully with a wire cutter (the hoses have a spiral wire reinforcement) and lever them off slowly with a large screwdriver. This was hard work, and quite slow, but I managed to get all the old hose detached eventually.
The deck gear for the anchor winch is broken in several places, and it failed to operate correctly when needed. We will investigate and replace parts as necessary.
We noticed in Penarth that our starboard navigation light was no longer working – luckily the following day’s sail was in the daylight back to Portishead.
We have a spare white (incandescent) bulb, but I want the navigation lights to use LEDs as these should last longer and use less power.
Our lamps use the BAY15D lamp base which are 15mm diameter, with double contacts and offset bayonet pins.
But what power to order? The COLREGS (International Regulations for Preventing Collisions at Sea 1972) has a table showing the minimum visibility range for your navigation lights, depending on boat length. The RYA has a useful summary table on its Lights, Shapes and Sound Signals page. So we can calculate that we need a minimum of 1 mile visibility for Molia which is just a little over 10m long. Also, special advice for coloured LED lamps is:
‘Do not place cool white LED lamps behind coloured lenses as they do not produce the correct colours for navigation purposes.’
So we ordered specifically red, green and (cool) white LEDs to replace our 3 deck-level navigation light bulbs (port, starboard and stern). Product: BAY15D 24 SMD 2835 High Output Compact LED Navigation Light Bulb (+3 miles visibility).
Supplier: Boatlamps.co.uk have a really helpful website that shows you what LEDs are direct replacements for your old incandescent bulbs. The site includes full descriptions and dimensions so you can reliably confirm that your new LEDs are the correct size.
These pictures show the new LED fitted on the starboard side. We cleaned the contacts and also added the Contralube 770 product to the contacts. This helps prevent corrosion and friction (vibration) damage of the contacts, so they should be more reliable in the long term.
We also took the opportunity to clean the rubber gaskets in our light enclosures, and lubricated them with some Vaseline to help keep them from hardening and cracking.
