Hi Blog watchers,
 
Roger Engineering officer reporting for duty.
 
Today is a big day for the engineering team because today is the day the teddy bears go---------- Oh no that's not right, nerves are setting in; the pressure is on because we finish the modification and test the water maker.  Crew excitement is mounting as the prospect of a hot shower gets closer, particularly since Chris is the only one to have showered for a few days.  There was no way any of us were going on deck when he was prancing about in the state of undress that he was in.  Mary you should have warned us of the traumatic effect Chris in red nicks would have on the rest of the crew, Graeme has been very quite ever since.  Further to the big day, we must wait until this pm before the big event since mother (Di today) has told us that we will not be allowed in the galley this morning to finish the wiring.  For the those of you who have nerdish tendencies I shall report the technical side, in detail, at the end of my blog.
 
As for the 'Yotting' I can report that during my 000-0400hrs watch I saw a yacht!  Big deal you might say but for the crew this is a major event.  An ARC yacht probably and only 1.5 to 2nm away because I could see her low level (no tricolour) navigation lights very clearly. Also of interest to us nerds she didn't show on the radar at any range!  Strangely she was going very slowly, 1-2knts maybe, and we overhauled her in less than 30mins.  We suspect that she had deployed a drogue since the weather and sea was been unkind to us most of the early night time.  With 25-30knts, occasionally gusting in the 40's, and 8-12ft breaking seas we were reefed down to a pocket handkerchief twin head set. Add to this the very wet weather that everyone, except me, had during their watch you can see that the Morale officer is in great demand.  This of course adds to the pressure on the engineering team.   Additionally Graeme Comms officer tells us that the we can expect wet stormy weather for another 24hrs.
 
On ARC position reporting I have to tell you that we are very disappointed with the infrequent, one, reports from Margaret so we are looking to fill this post.  The post holds good promotional prospects Richard?!
 
 Ok this is the end of life aboard the good ship Zepharantes.
 
For nerds only:
 
At this stage our solution is not proven but we believe that the raw sea water is not getting to the High Pressure pump.  The HP pump is positioned just below the waterline, maybe only 100mm below, and is fed raw seawater by virtue of the head provided by being below the waterline.  The system has worked satisfactorily many time in relatively calm sea conditions and not in a large seaway with the boat rolling heavily. Our proposed solution is to feed the raw water to the HP pump via a feed pump.  Interestingly, well to some of us, I have read of similar problems on ARC boats over a number of years where air gets into the watermaker system.  Zepharanthes has a glass top to her inlet strainer and air bubbles come in when she surfs and/or rolls.
 
With all fingers crossed,
 
Signing off.
 
Roger
