Darn engines🤬🤬🤬🤬

I thought I would run the engine yesterday for the first time in a couple of months, a few minutes later the overheating alarm went off. 

There was water at the outlet from the water strainer, so I took the pump off then it's back. When the shaft was turned the impeller didn’t, the bonding between the rubber impeller and the metal centre had failed and it was easy to separate the two. 

The water pump looking from aft.
Visually in good condition except its now in
two pieces.
I change impellers annually in the spring with Yanmar branded ones so it has one seasons use. I suppose I should be grateful that it didn’t fail when I was rushing back to the Hamble from Hope Cove in August for a family emergency; I carry multiple spares and could have fixed it in an hour but it would have been quite stressful until I found the fault and dangerous if it had failed going through the needles channel with little wind.

The assembly is getting a bit tatty where bolts bear on it and as I want to replace some of the pipe work, (including the bit shown above) and check the engine anodes I am leaving the engine drained of water for a while and have the unit at home for the clean up and repaint.

More winter work

The burn holes in the carpet has been bugging me for years, time to replace. Taking the cabin sole home to work on it led to cleaning the bilge to keep the smell down and whilst about it the fore and aft sections of the bilge needed a clean and a coat of paint, the teak faced boards over these sections were varnished not that long ago and don't need to be redone.

The aft section was easy having had a coat in 2022 when the
sea cock was replaced.
The section in the heads needed a bit more work on what was
almost certainly the original paint. Some wiring also needed
tying up - stick on pads don't seem to last long on a boat. I
added the rubber strips some time ago to stop the board rocking and
squeaking, a small section, lower left, now needing to be replaced.
The underside of the main section of the cockpit sole after what
was probably the first coat of paint in 45 years, but it had done well,
the board is in very good condition albeit with the centre bowed
down ¼" in places which may explain why the table has been
tricky to fit (the aft leg of the table goes over the block of wood).
Two coats of the excellent International "Danboline" bilge paint.
Two coats of varnish for the base of the table leg, two more to go.
Plus a cleaned up and lacquered ring lift. I'll be adding a second
 one to the forward section which will make it much easier to get up
and save pulling on the carpet.
I  replaced the carpet with carpet tiles; cheaper, easier to source, hard wearing and with some spares it will be possible to replace small sections if one gets damaged. It was also probably easier to cut them to shape than a single piece would have been.
Trial fit of the table base on the aft section.
Front and centre sections, waiting for the second lift ring, the
2 slide bolts that hold the centre section down and a tie down
 point will be refitted when the boards go back in the boat,
when the weather permits.
The aft section is screwed down, the middle section secured with
slider bolts. Also one of 3 tie down points for under table storage.
The electric bilge pump and the hose to the main pump are 
accessible  with the middle section lifted.
Job almost done, just needs the additional
lift ring.
Job done.

My review of anchorages and marinas around UK has been updated through Sept 2023.

Sancerre in the anchorage at The Holy Island of
Lindisfarne, 2021
, the Farne Islands and Bamburgh
Castle in the distance.  A trip line is required in
this anchorage, to see why click here.
My review of anchorages and marinas around UK has been updated with those visited through September 2023, at that point I had been to 141 since getting Sancerre, almost all have at least some comments. The pages were getting over long so there are now nine of them. 

I now include:

  • Harbours and Marinas.
  • Some info on fuel & gas availability but I would not have checked at many locations. 
  • Cell coverage, Vodafone and O2, for those I have visited recently.

Be sure to check out Reeds  and / or the appropriate pilots for more detailed information and alternates, this is just an overview of likely candidates, but I have been to all of them over the last few years. Some notes on passage making using some of these can be found here:  "Planning a round GB trip" , a list of charts and Pilots I have used round GB can be found here: "Charts and Guides for a round GB trip"

Note that these "Pages" do not show up under "Post Labels" (right). There will normally be more photos of each anchorage on the linked post and sometimes subsequent ones (I normally only "tag" the first post in a sequence) the associated slide show, or by clicking on the Post Label right:

Memories, good and bad.

Back in late 1977 I joined Brian & Pam Saffrey-Cooper's crew running the front half of his Contention 30 "Buccaneer", that however was not the end game. That autumn there were meetings including one very long and late one at The Chequers Inn, Lymington, with Doug Peterson one of America's leading yacht designers, to finalise the design and layout of a new 1/2 tonner to be built for Brian (AKA "Hooter") by the Elephant Boatyard at Bursledon. Brian was a timber importer so she was built in the finest Western Red Cedar on Sitka Spruce and was very light but strong.

She was launched just before Easter, but a major problem cropped up in trying to find a name for her; Brian, who was rather superstitious and liked to have boat names ending in "eer" as in Buccaneer and his previous 1/2 tonner, a Norlin designed Scampi  "Racketeer" (not that good a name for a businessman!). The crunch came when a name had to be found to get the boat measured for her rating, they passed a pub called "The Green Dragon", green was Brian's lucky colour and already chosen for the hull colour so the name was decided.

Green Dragon on the way to winning our division
in the Round the Island race 1979. I am sitting out
waiting for the next sail change.
Although we did not manage to achieve our goal of winning the 1/2 ton cup, either at Pool in 1978 or in Scheveningen in 1979 when we suffered rudder failure, or even to come out as top UK boat in those events, but we did win the selection trials from 50+ competitors in 1978 (which was an off year for the Admirals Cup) and finished 7th in the event from 50. Overall she was the most successful British 1/2 tonner in 1978, 1979 and 1980 (I did not sail on her in 1980 but returned to help Brian get his one tonner "Dragon" into the winning Admirals cup team in 1981). She won the division in RORC, Solent Points and British Level Rating Association series in all three years - believed to be a first. We also won the RORC yacht of the year award in 79.
My favourite headline from 1979. Bob was a little biased, he
crewed for Brian & Pam on Racketeer, I think his introduction
to offshore sailing after very successful campaigns in dinghies
and crewing for Reg White winning the Little America's cup
for "C Class" Catamarans.
Then about 5 years ago, after I got my own half tonner as a gift to myself on my second retirement, Green Dragon was run down on her mooring, this from Doug Peterson's office after I shared the picture on Facebook (neither Brian or Doug lived to see her demise):

Then to cap it all she sank and last year(?) these pics came out.:

Such a shame to see such a beautifully made boat end up like this.

Installing a holding tank - Design.

With the slope of the hull and the web
supporting the aft lower shroud fitting
there is not a lot of room behind the toilet
and none under. Securing a sometimes
heavy tank would also be difficult.
To be more environmentally friendly and to avoid some trips ashore for "comfort breaks", I have been toying with the idea of a black water holding tank for several years but its not easy because of space constraints. 

Older boats are not required to have holding tanks in most jurisdictions, regulations vary by country but generally waste can be discharged when more than 3 miles offshore, perhaps unsurprisingly (in 2023) there are no restrictions on discharging waste in UK coastal waters although many marinas and harbours have local regulations or by-laws banning discharges.

The space behind the toilet could take a tank but to be anywhere near a useful size it would have to be bespoke and therefore very expensive, it would also be difficult to fit to the sloping hull, difficult to plumb in and I would loose some small but handy storage space for toiletries and loo cleaner. 

Underneath what was the port berth in the forepeak or under the port berth in the saloon would both easily take a rubber tank but they are difficult to secure and I don't fancy a rubber tank full of sewage anywhere in the boat. Again solid tanks would have to be specially made and both options would require lots of expensive plumbing with diverter valves, pump, etc..

More realistically with the forepeak no longer having berths, a tank could be installed there on the port bulkhead next to the heads. 

If the tank bottom is high enough above the waterline and the pipe work reasonably short and not too bendy this could be emptied overboard by gravity and, with the appropriate fittings, optionally by pump out. 

Again space and cost are issues; an excellent vertical tank is made by "Tek-Tanks" it is made to order in standard sizes with inlets and outlets positioned to order. There are problems, space is at best barely adequate for the smallest 40 litre version, there might not be sufficient "head" for it to drain correctly, and the tank without hose tails is £389. A similar but much cruder design by Nuova Rade is only £159 but again it would be difficult to fit and drainage could be an issue. Both options could be made to work with a lot of plumbing and a pump to drain the tank as sea but it gets expensive and complicated.

Schematic of the planned installation.
I gave up on the project the last couple of winters but this year I found a 25 litre horizontally orientated tank by Vetus that is much shallower so gives more space for installation above and below and a better head for drainage, still £270 but unlike the other tanks that does included all the hose tails bar one.

The height for gravity drainage looks to be OK even if a couple of elbows are required, especially as the electric pump and Macerator does a better job of breaking up solids and paper than a manually operated toilet.

When offshore the seacock is left open and waste goes straight out, in sensitive areas the sea cock is closed and the waste accumulates in the holding tank later be released at sea or pumped out.

If in use the gravity drainage proves not to work there is room to install the new Henderson Mk5 pump I happen to have (its a long story) between the tank and the seacock. That would be a pain at sea requiring manual pump outs but it would work and I could add a diverter valve and additional pipe work.

The back up plan (see next post for an updated final version).
Outline plan for the bulkhead mount.
Most of the components are on order and should be here by early next week, the rest I'll get locally some after trial fits, and I'll start the installation when there is some decent weather to visit the boat.

Installing a holding tank - Installation, Day 1.

I'm glad that I did not try using a 40 litre tank or even the 25 litre vertical, at best it would have had very complicated pipe work, needed new and tricky to build head lining and would probably not have self drained properly. 

The bad news was that due to a number of factors, mainly positioning of the filter and the length (depth) of the deck fitting for pump out, I had to put the tank lower than I had hoped so gravity draining was still going to be problematic and would probably not have worked at all on starboard tack so I switched to "plan B" and am fitting a pump, diverter valve and a stop valve between the tank and the discharge pump. The existing inlet pipe work and the anti-syphon loop can be reused without modification which will save some time and money.

The end of a long days work (finished at 19:00),
the pipe to the filter needs a clip to hold it up so it
would drain back to the tank if any water got in.
Apart from that I made good progress, 

  • The panelling in the heads is out and most of the black mould behind removed, the rest will go when I have moved some pipework.
  • The tank is mounted with a substantial block underneath that is bolted through the bulkhead to support it.
  • Inlet connected at the tank end and taken through to where the diverter will go.
  • Vacuum pump out piping completed, the head lining hides the deck fitting and just needed a small piece taken out on the aft edge for the pipe to go through. 
  • The filter is fitted to the bulk head and the inlet pipe fitted, it is close to the head lining but to change the filter the headline can easily come down, its held up by Velcro, and there is oodles of space above (where I had thought to put the filter).

The pump will go under the former port bunk, I have it home and it's now fitted to a mounting board ready to install. The locker lid has been shortened to open past the tank, the off cut will go back in with the waste pipe going through it. I'm now waiting for the diverter valve to be delivered and I should be able to finish the job in another long day.

The main problem fitting the tank lower was difficulty in siting the
pump out fitting to get the pipe to the tank without interfering
with the inlet pipe or getting in the way. In the end I put it on the edge
of the coach roof rather than on the deck. Further inboard would have
given a good lead but then there would be nowhere to put the filter
with the bottom of the unit and pipes above the tank and outlet in
the chain locker.
The fitted unit, I was quite pleased with the neat fit to the
Treadmaster anti-slip pad.

As fitted.
