September 2020: Same Old Stuff, Only Different

The intrepid sailor and circumnavigator, Eric Hiscock, once said “the only way to get a good crew is to marry one”, and there’s tonnage of truth in that.  And if you know anything about Ghost Rider’s crew, then you know our Chief-of-the-Boat (Michelle) is a list-maker.  All kinds of lists.  There’s always the “to do” list, but also lists of recipes, ingredients, galley supplies, durable foodstuffs, fresh produce, frozen food, shoes, whatever. And the shopping list.  She may have lists of lists. Fortunately, some time ago she discovered an application, called “AnyList” (LINK), which makes all that enumerating and cataloging very efficient.

An "AnyList" Screen Shot

Chelle has also been a long-time fan of the “The Boat Galley” web site (LINK) where Carolyn Shearlock has long advised cruisers on tips and tricks for the voyaging couple.  Carolyn asked Chelle to write an article on how she uses the “AnyList” app, and you can find the result of that collaboration at this LINK.  Note that while it’s mentioned as an option, we do not use the app for tracking boat parts or spares.  (For us that still remains in the realm of our Wheelhouse software.)

Break/Fix (Davit Update)

As for the davit’s new HPU, Ross’s machine shop is just now completing its modification work, which is fairly extensive.  

The HPU Manifold Assembly is Requiring Significant Surgery

Two aluminum blocks were machined to match the fluid ports and fastener holes on the new pump and manifold.  Those blocks also had fluid ports machined to accept o-ring boss hydraulic adapters.  Then the blocks were bolted to the pump and manifold, and a base is being fabricated for the valves. 

Next up will be to install the modified HPU after which it will be necessary to make up new hydraulic hoses for the pressure and return flow.  So there is still a lot of work left before we’ll know if we can make it all work.

Salon Ceiling Panel Removed to Reveal Water Leak Location (Yellow Arrow)


Along the way, the removal of the old HPU from within the base of the davit housing had exposed an electrical wiring run which goes through the boat deck level and down into the salon ceiling void area.  And that had started to leak rainwater inside the boat on the starboard side of the salon.  We took down the ceiling panel to locate the source, and then it was an easy task to apply some silicone caulk (at the boat deck level, inside the davit base) to resolve the issue.

More Break/Fix (Main Engine Water Pump)

While we were not exactly sure it was “broken”, the main engine’s raw water pump had developed a small oil leak at its engine block adapter.  That usually means a deformed o-ring, although there was the lingering doubt about more significant internal pump issues.  So Rick decided to remove and replace it with our spare pump with a new impeller.  That sounds simple, but access is a real bear, and it took him several hours over a couple of days.  Subsequent testing demonstrated the leak was resolved, and Rick then sent the leaking pump to the Depco Pump Company (LINK) in Clearwater for evaluation.  They were – as usual – very prompt, and recommended that both the pump’s internal water seal and oil seal be replaced; for $190 (on a $1600 pump) that was worth it.  It took all of three days to ship it, have it examined and rebuilt, and get it back into the spares bin.

The Old Raw Water Pump Being Removed....Not a Fun Job

Project Work

When you acquire a boat – any boat – whether you acknowledge it or not it comes with its list of projects.  Whether you write them down or not is also immaterial to the reality, that list is there.  There is also a Murphy’s (maritime) Law that states any time you cross one project off the list, two more will appear to take its place.  It’s maritime magic.  If the Greek mythologists were more attuned they would have made Sisyphus a sailor.

Next up on our docket of boat projects was related to a time-based deadline, specifically the expiry date for the boat’s pyrotechnic signaling devices – primarily red flares and orange smoke.  For the record, those things expire at 42 months from the manufacturing date.  Our inventory included not only the hand-held flares and smoke devices, but also flare gun cartridges and SOLAS certified parachute flares, along with sea dyes.  An inventory refresh for a well-equipped voyaging vessel can easily run around $500 USD.

We have periodically tested expired pyrotechnics – New Year’s Eve and Independence Days are the best nights in the USA unless you want to entertain the consequences of an accidental SAR mission – and they’ve always worked.  Testing or practicing at any other time requires USCG and LEO notifications, and a securité call on VHF channel 16.

When we crossed the Atlantic back in 2017 we also had five vessels fire off an impressive variety of expired devices one night (quite literally in the middle of the Atlantic Ocean) and they all performed well.  The SOLAS parachute flares, by the way, were by far the most impressive given their brilliance, illumination time, and altitude / visible range.

The Array of Signaling Devices We Carry in Our Ditch Bag...with the New eVDSD Device in the Middle

The bottom line is if you store your pyrotechnic devices properly (waterproof container) and inspect them regularly (checking for damage), they will last for years beyond the expiry date.  But should you rely on expired stuff when safety is at risk?  Probably not.

But there is now another sensible alternative, and that’s the electronic Visual Distress Signal Device (eVDSD).  It’s only in recent years that these have received USCG and SOLAS approvals, sporting powerful LEDs which automatically emit the visual Morse code for SOS, built-in flotation, and user-replaceable batteries.  Replace the latter once a year and they never expire.  Combined with the standard daytime distress flag – and an arsenal of expired pyrotechnics – you can remain legal and safe for a one-time outlay of $89.95 (plus a few bucks annually for batteries.)  We chose the Sirius brand, but Orion makes a decent one, too.  There’s a good explanatory article at this LINK.

The next project was one that we had been debating for a while, and that was whether to upgrade our navigation software.  On Ghost Rider we use Furuno TimeZero Touch2 (TZT2) MFDs and also Nobeltec’s TimeZero Professional on the ship’s PC.  As you might guess from the shared “TimeZero” labeling, the software for both systems share an integrated architecture, so care must be taken to insure version compatibility between the two.  When Nobeltec introduced V4 of their TZ PC software in early 2020 it included a warning that its Furuno integration would break without the next version of TZT2 (version 7), so we waited for that.  Then the debate was whether the price was worth the gains.

These Types of Screens Make You Hold Your Breath....But It All Went Smoothly

In the end the price tag was nominal (Furuno’s upgrade was a freebie, Nobeltec’s was not) and we did not want to be in an upgrade-limited box canyon, so we pulled the trigger this month.  While it was a distinct pain-in-the-ass to upgrade both systems, overall it went fairly smoothly.  The Furuno side of it required separate upgrades for each MFD (involving downloads to both microSD and USB flash memory) and took a couple of hours.  The Nobeltec side of it was predictably less time-consuming – it basically was your typical PC-based software upgrade, although we did hit the limit on number of routes it could convert and support (200), easily overcome by removing duplicates and unused “what if” routes.

The New (V4.1) TimeZero Animated Weather Screen is Cool....Leaves No Doubt Where the Gulf Stream Current is Ripping Along.
Post-upgrade testing showed all functions to be ops normal, and Rick spent some time playing with most of the new features on both subsystems, all satisfactorily.

Finally, it was time once again to test out all of Ghost Rider’s bilge pumps.  The nuisance water pump (a Whale Gulper 320) gets a daily workout just expelling air conditioner condensate, but the other three dewatering devices require a special effort to verify their operation.  So Rick ran a dock hose down to the engine room, turned the nuisance pump breaker off, and flooded the bilge until the high water pump float switch kicked off the next pump (a Rule 3700) and triggered the high water alarm.  That revealed a problem, which turned out to be a blockage near the through-hull at the stern of the boat back in the lazarette; repeated cycling of the through-hull handle along with a coat hanger auger and a high pressure water hose took care of that.  (There’s a lesson here: we’ve discovered that any through-hull that has a 90 degree bend near its exit port needs periodic testing and cleaning.)

The Pacer Hydraulic (Crash) Bilge Pump....Capable of Expelling 10,000 Gallons per Hour

Next up was the manual pump (an Edson 638) which primed and pumped as advertised.  And last was the hydraulically powered emergency crash pump (a Pacer centrifugal model rated at 180 gallons per minute)….we leave that until last because that beast will completely empty a flooded bilge cavity in a matter of seconds – and it did (after priming.)  In the process our Monnit high water remote sensor also dutifully alarmed and sent its remote notification, so we declared victory.

Weather Check!

To say that the tropics were – as predicted – heating up this month would be quite the understatement.  By mid-September the NHC's map of the Atlantic basin and adjacent seas looked like a video game of tropical pinball.  Here in Fort Myers we got all of 24 hours of notice when TD18 formed just east of Miami, and by the time it cruised past us a day later became Tropical Storm Sally, mainly as a rain event.  But by the time it reached the next shoreline at the Mississippi-Alabama border it had reached hurricane status and dumped about a year’s worth of rain there as it slowed to a crawl for several days.

Tropical Storm Pinball...as of 14-Sep-2020

Luckily all those other named storms got steered out into the Atlantic, pin wheeling towards Bermuda or otherwise heading into vast open ocean areas.  As the month progressed the number of storms finally exceeded the normal allocation of names (all 21) and progressed into the letters of the Greek alphabet.  Even the Mediterranean and the coast of Portugal encountered tropical systems this month. 

Sally Skirted Us as a Tropical Storm then Moved on to Clobber Alabama as a Cat-2 Hurricane

Wait, why do we only use 21 letters of the alphabet, why not all 26?  Naming these systems has a long and tortured history, but first note that it isn’t NOAA/NHC in the USA that decides such things – it’s the World Meteorological Organization (WMO) international committee that does that.  They actually maintain lists of storm names for four separate ocean basins (one for the Atlantic/Caribbean/GOM, then three others for the different Pacific Ocean regions).  And there are actually six such lists for the Atlantic basin which rotate on a six year basis – except for when a really nasty storm gets its name retired.  The Atlantic list doesn’t use the letters Q, U, X, Y or Z because there just aren’t enough available (and recognizable) names that begin with those.

Towards the end of the month the tropics settled down for a spell, but we expect the activity will pick up again in October.  To make it more entertaining, that’s the time of year when such storms tend to originate closer to home – in the Caribbean and GOM – which tends to give folks less prep time.  We’re two-thirds of the way through hurricane season, but there’s more to come.

Afterword:  It’s only slightly humorous that many in the USA are acting shocked that their government has been lying to them about Covid-19 since late January.  As if that was a new phenomenon.  Just as interesting were those twisting themselves into knots trying to explain it away as some bizarre and nouveau form of leadership. We continue to look to science, wear our masks, keep our distance, and long for competent governance.

Aug 2019: Miscellaneous Boat Business

Looking Down Into the Bilge Cavity Which is
Just Aft of the Main Engine, with a Water Hose
Pumping Water In at a Pretty Good Clip.
The summer weather in southwest Florida is rarely an attraction, but this year it truly sucks.  A persistent westerly flow has been bringing copious amounts of moisture, so not only has it been raining every day, it has been raining all day.  And some nights.  Based on the decline of El Nino and NOAA's latest tropical storm forecast, we've calculated the rain might stop some time in November.  Ghost Rider may be our ark.

Still, even as we were enjoying the distraction and satisfaction of recently completing two special projects – for the boat’s remote monitoring and CCTV systems, see two previous blogs – we of course continued to pay attention to the periodic duties that Ghost Rider requires to stay (and keep us) happy. 

It is not normal to wake up one morning and think “let’s see if we can flood the boat today”, but that’s essentially the approach required when it’s time (annually) to test out the boat’s bilge pumps.  Ghost Rider has four of those as part of its de-watering systems.  Two are DC powered with automatic float switches: a Whale Gulper 320 for nuisance water and a Rule 3100 for high water, with 300 and 3,000 GPH ratings respectively.  A third is manually operated via a hand pump; that’s an Edson 638 with a gallon-per-stroke rating.  And the fourth is a Pacer crash pump which can evacuate up to 10,000 GPH – that’s about the volume of an average domestic in-ground pool here in south Florida – and is hydraulically powered via the PTO coming off the wing engine.

Lazarette.  You Can Tell It's a Serious Pump by the
Size of the Input & Output Hoses.
After dumping a prodigious amount of fresh water into the bilge via a garden hose – about 40 gallons based on what was drawn down from our forward water tank – all  pumps were working, although Rick wasn’t particularly happy with what appeared to be intermittent suction from the big Rule 3100. He later disassembled that to check for debris clogs, but to be completely safe we ordered a new Rule 4000 GPH pump to replace it.  The big Pacer hydraulic unit required some manual priming which is normal for anything other than a full down-flooding event, but once primed it sucked out the entire bilge in a matter of seconds; that thing generates an amazing fire-hose stream of water out the back of the boat. 

And the recently installed remote sensor dutifully reported its detection of high water, but also revealed a weakness – it wouldn't dry out and kept triggering alarms.  After huddling with the vendor (Monnit) it was determined that we had a faulty unit and they shipped a replacement.  Rick fashioned a new mounting method for this one  (vertical vs. horizontal orientation, and a few inches lower) and thus far it is behaving.  To illustrate we have added a couple of updated photos of the bilge area towards the bottom of this post.

As mentioned in a previous blog we also needed to figure out what was wrong with the master stateroom's air conditioning unit, which had started throwing “HI PS” (high pressure) warnings and shutting itself down.  After a week of trying his home remedies with no resolution, Rick called an A/C tech out to the boat; when he showed up as scheduled one morning, we cranked up the air conditioning unit in the master stateroom….and it performed flawlessly.

No "HI PS" errors, just a constant flow of nicely chilled air.  We had the tech (Craig, from VIP Marine, LINK) check the system for pressure, component temps and overall system health – all of which he pronounced to be sound.  Puzzlement.  Theoretically the issue could be a control board about to go bad, or an intermittently sticking pressure switch, or just a piece of flotsam that unstuck itself from the cooling loop…with the latter being the most likely and preferable.  But at any rate the problem seems to be gone.  Perhaps occasionally you just get lucky.

Not a Difficult Task to Buff Out, but There Are 40 of Them.
Moving on from that, we turned our attention to another minor item on “The List” of things to do.  This one was to replace or repair the overhead lighting trim rings that dotted the ceiling panels in the pilot house, galley, salon, and both staterooms (and heads).  The faux chrome plastic bezel rings were thoroughly pitted and turning green after 17 years of salty exposure.  

As it turns out, rubbing them down with a 3M Scotch Pad soaked with white vinegar restores them quite nicely and is a lot cheaper than buying new ones.  But there are 40 of the damned things and that took a while given the difficulty of prying them off and snapping them back on.  (After the first dozen or so we learned a useful trick: lightly coat the inside of the snap-on trim ring with Superlube synthetic grease… after which they became much easier to reinstall.)

Next, with the deluge of monsoon events here, we discovered a rain water leak in the pilot house.  It didn’t take long to narrow it down to the Sirius/XM satellite antenna wire where it fed through the pilot house roof.  Coincidentally the Furuno (BBWX3) weather receiver started complaining about intermittent antenna signaling, so Rick decided to just rip out the whole thing and start fresh by installing a new one, a Shakespeare SRA-50 unit.  That turned out to be a good idea as we found frayed wiring inside the old unit.  Once the new one was operational the Furuno weather receiver was back to its ops-normal happy state, and the new gasket / caulking had solved the rain water leak.

Another annual fun job that came due was to remove and clean the tank level probes for the black water holding tank.  This isn't a difficult task by any means, but it isn't a particularly pleasant one, either.  The most important tools involved are a pair of nitrile gloves for your hands and a clothespin for your nose.

the Tank-Level-Probe Assembly that Needs to be Removed & Cleaned Annually

The device itself is dead nuts simple, with three adjustable level floats attached to a threaded top cap, and easy to remove (after labeling and disconnecting the four lead wires.)  We then placed it into a large bag-lined bucket to (quickly) carry outside for a thorough hose down.  We had replaced the original probe assembly with a new one when we first bought the boat, so it was in pretty good shape, easy to clean, and simple to reinstall.  Rick followed up with a healthy shot of air sanitizer, also replacing the vent line charcoal filter, and those should not require attention for another year.

Lastly, it was obvious that Ghost Rider was in need of some TLC on its fiberglass exterior.  While the light grey hull still looked good, above the gunwales was another story.  Months of Florida sun and rain -- absent the daily chamois mopping since we were no longer living aboard -- left a lot of white fiberglass looking less than white; dirt stains were digging in.  In between rain showers we spent several days of washing with Z-Tuff, removing tougher stains with Collonite fiberglass cleaner, followed up by applications of Collonite boat wax.  In the exhausting and soupy heat of a south Florida summer it reminded us why we normally try to be elsewhere at this time of year.
