Pleased to report that FW tank repair is holding with a 60% capacity, made up by rain running into the after tank and with use of the OS system providing water during the day.
Following that job Gerry has been taking it easy, socialising with their sailing buddies in the CAT, whilst they complete jobs and await developments for returning to the US.
Gerry is also waiting for spares for the RO and looking at what further ports/ countries are open to them as they head towards Panama, Columbia being a favourite at the moment.
Hydraulic control station. It's located in the cockpit just underneath the companionway stairs. Gerry wants me to write a very complicated explanation of how it works but I've tried to keep it simple so as not to confuse you too much. Its purpose is to hydraulically pressurize the backstay tension adjuster (which holds the mast in the desired position) and to hydraulically tension the boom vang. The boom vang pulls down on the boom to tension up the leach (the longest edge of the main sail, furthest out from the mast) giving it the best sail shape possible. The operation is achieved by inserting the pump handle, shown at the bottom, into the hole on the board, turning the three way valve for which ever function you want and pumping the handle until the desired tension is achieved then putting the valve in the locked position. I hope I haven't confused you too much - a little confusion is good enough!
Blooming hydraulic oil leaks I hear you former Mates muttering, shades of the 'A' Boats.
It was during a repair to one of the cranes on the Avelona Star that my (now) wife first saw me in all my minty glory, something must have impressed her, cannot think what. Nobody received any training on the cranes or hydraulics (unlike today when you have to have been on a course for any new equipment before you can touch it). When anything goes wrong you always seem to look for worse case scenarios, in this case it turned out to be a new main joint was required. Apart from not knowing about the cranes or hydraulics the manuals were written in Scandawegion but a £1's worth of jointing material cured the leak.
When reading the SailBlog I sort of skimmed over the Advent photo thinking it was a polystyrene carry out box with Christmas Lunch ready for a reheat and a packet of apple sauce which turned out to be the Man Overboard apparatus.
Oops! BOT wouldn't have been too happy with that. Perhaps having spent my 10 years in stygian darkness of the Pit with the infernal combustion machines had an effect on my eyesight, plus old age of course, as the Dr. or Optician would say.
They are a type of rigging, applied to a fore and aft rigged sail to aid in the reefing (making the sail smaller) and furling (putting away) of the main sail. They are a set of lines which are attached to the mast and to a series of points on either side of the boom forming a cradle. Ours have the addition of a sail bag through which they are threaded so that the main sail is guided into the sail bag on top of the boom when it is lowered. They are a time and effort saving device as no one needs to secure the sail (in the past we had to flake it from side to side and then secure it with straps to the boom), we just have to zip the bag up when it is all in place now.
Conventional thinking is that the term "Lazy Jacks" evolved from the term "Jack Tars" the description used for British Sailors of years gone by and because this type of rigging negated the need for sailors to manhandle the sail the term "Lazy Jacks" was applied to them.
Not much going on at the moment, they might be at the idylic (according to travel brochures) island of Granada, but they recently had rain and now there is a bit of a swell washing up into the anchorage causing them to bob about like a cork, so much so that Nicky was going to put some tea towels in a bucket of water with dhobi dust and use the motion like a washing machine, why not, it used to work for us.
Sounds like they maybe going on a charabang tour/ pub crawl round the island starting at the Brewery so there might be a few different images coming up, Nicky is not much of a drinker (spills most of it) so she will be in charge of collecting photographic evidence for blackmail (her words).
To the left in the photo are two blue filter housings, the one at the top, labeled as the "fresh water flush" is a carbon filter used to clean the system of salt water if the system isn't going to be used for a period of greater than 2 weeks. The other blue filter, at the bottom in the photo, is a 5 micron filter for filtering sea water going to the high pressure pump,(not shown in the photo as too difficult to get to). On the right hand side at the top of the photo you can see the control panel with the hose just visible, over the top, which takes the reject water back overboard. From the 5 micron filter the water goes to the membrane (on the right side middle of photo) where at high pressure it allows water to pass through whilst keeping salt out. Fresh water travels to the water tanks from here. The final photo on the right hand side, at the bottom, is of the salt water intake pump, which pumps sea water into the 5 micron filter allowing the process to convert sea water into fresh water by reverse osmosis (I knew that bit of science would come in handy for my blog some day!).
One final word about RO water, when we have the water maker running we start off having the resulting fresh water pass through a hose rather than to the tank so that we can test it for Total Dissolved Solids with a TDS meter - this is the measure of how much salt remains in the water after passing through the process. The acceptable TDS, according to WHO, is 500 parts per million, as extra precaution we don't put the resulting water into our tank unless the reading is less than 300 part per million. Once it shows below 300 TDS (usually about 3 cups worth of processed water) we switch the water hose over to fill our tank. Water makers come in many sizes, producing varying amounts of fresh water in an hour. Our particular water maker is supposed to produce 4 gallons an hour but at present we are awaiting a new control box (coming via the moon) as our production is down to 2.5 gallons an hour, due, we think, to a leaking bypass valve in the control box. At least we are producing some water!
One does wonder about the other things that might be in the water, not just salt, how good are these filters. The yatchs are in a bay close to land, what's to stop somebody discharging their sewerage tank over the side, overnight every so often. There could also be run-offs from ashore also. No heat is used in the production of the water which would tend to kill off some of the nasties, yet Nicky and Gerry keep healthy.
This is the infamous manual toilet flush valve from the fwd WC that Nicky is always having trouble with.
