October 2020: Back on the Boat

Coping with Covid can often feel like déjà vu….as in, what day is it?  It’s today.  Still.  It’s like a really bad version of the movie Groundhog Day, but with annoying masks, no hugs, and a pathetic plot.  Rick gave up on remembering days of the week and now calls each day “Blursday.”

View of the Portion of the Condo Where Kitchen & Wall &
Floor Tile Were All Ripped Out

Chelle got so bored she decided to demolish about half of our condo as a distraction. Presumably that was in preparation for a remodeling effort, and Rick evacuated to the boat just before the jack hammering started.  That turned out to be good timing as we had a lot going on in terms of Ghost Rider activity.

Break/Fix

Rick had invited Craig of VIP Marine out to the boat to evaluate a cooling problem with the A/C unit for the pilot house.  That’s a relatively new compressor/evaporator combination (barely two years old) but its cooling output was trending 10F warmer than all the other units.  That’s enough deficit to greatly impact the pilot house with all its greenhouse-like glass.  Craig showed up on day one of the condo exodus and slapped the gauges on the suspect compressor.  That revealed a lack of refrigerant pressure and volume, so he pumped it up with the R410A stuff, providing an immediate improvement.  We did not find any leaks in the obvious plumbing places, so we’ll run it for a while in the south Florida swelter and see how it holds up over time.

Jerry & Ross Trying to Figure Out How to Fit the New HPU
Assembly into the Too-Small Space in the Base

At about the same time Ross and Jerry of Class Yacht Services showed up with the heavily altered HPU for the davit/crane.  The machine shop mods to the fastener holes, fluid ports and hydraulic adaptors still allowed installation room in the base of the davit, but it was a very tight fit.  Sleuthing the electrical connections took a while as we did not have the benefit of a good schematic, but Ross was able to cobble together a reverse engineering of the wiring.  New hydraulic hoses were then fashioned and connected.  All that took a few days.

Then it was time to add hydraulic fluid (about two gallons of ISO 68), apply power through the circuit breaker, connect the control pendant and test it all out.  We got good movement of the hook up and down, and of the boom to port, starboard, and down – but it would not raise.  Suspecting that particular control valve had a blockage in the “up” direction, they again removed the valve manifold and took it to the shop for individual valve testing.  Some debris was found and removed but upon reassembly back at the boat we still faced the same problem.

So, we all stood there and stared at the crane for a while, waiting for some inspiration.  It came to Jerry:  while the motor would run with the “boom up” command the valve might not be opening via the magnetic coil actuation, or in other words, it was an electrical issue. We had previously requested an updated wiring schematic for this later version HPU from the manufacturer (Aritex) in Taiwan, but had received no response.  Revisiting the control box wiring with a Fluke volt meter eventually led to the discovery of a well-hidden orphan ground wire.  Once it was connected, we were back in business.  The final touch was for Rick to clean and polish the base, and to drill an additional drain hole at the rear of the davit’s base.

This is How the New HPU Assembly Looked Before We Turned it Over to the Machine Shop
for Some Significant Modifications

In Place of Where the Valve Manifold Used to be, the Machine Shop Created a New and
Smaller Interface Block to Mate with the Relocated "Remote" Valve Manifold

Regular Maintenance

It was also time for Ghost Rider to get her periodic spa treatment.  Based just on visual evidence she was actually overdue – while the light gray vertical hull surfaces below the gunwales still looked pretty good, after 11 months the white FRP surfaces above that were getting that dull weathered look.   And keeping it clean was becoming a real chore.

The Bow of Ghost Rider Getting Detailed

We engaged Frank of Ultimate Marine (LINK) once again to tackle the enormous job of washing and waxing the entirety of the boat’s exterior.  Over a period of six days he and a few helpers got Ghost Rider looking spiffy once again, with the aid of electric buffers and copious amounts of Collonite Fleetwax on the FRP and Flitz on the brightwork.

Next up was the bi-annual service for Ghost Rider’s two Vacuflush toilets.  We had been experiencing minor and periodic issues with a temperamental water valve on one of them, along with a slow vacuum leak on the other, so Rick lobbed a call to the local Dometic shop. Travis and Gary from Fleet Repair (LINK) tore down and replaced the key serviceable parts for both heads, and also serviced the two vacuum pumps with motor mount adjustments and new duckbill valves.  It’s always good to have a smoothly operating waste water system.

Ghost Rider Looked a Lot Better After Frank & His Crew Finished Up

Project Work

Rick focused on a short list of “little stuff” this month….touching up paint scars in the engine room, refreshing Denso tape wraps on some hydraulic fittings, polishing corrosion from the pilot house Stidd chair base, and drilling a new drain hole for a fly bridge storage box.  The gas tank and spare gas cans for the dinghy also got reinforcing shots of Sta-Bil fuel conditioner – that stuff loses its potency after about a year. The overall punch list actually – finally – got a tad shorter this month.

Rick Got Some Cleaning & Detailing Work Done in the Engine Room, Too

Tropical Weather Check!

Hurricane Epsilon spun up into a major storm but fortunately stayed out in the open Atlantic, even missing Bermuda (barely) as it curved away from the U.S. and far to the northeast.  Then, as expected, yet another tropical system spooled up in the Caribbean this month and eventually made its way into the Gulf of Mexico.  Now deep into the Greek alphabet names, Hurricane Zeta got steered away from us by a high pressure system to our east and took initial aim at the Yucatan.  And then, following a disturbing pattern this season, once again the Louisiana coastline was bore sighted.  It would be their fifth of 2020.

After Five of These We're Guessing Land in Louisiana & Mississippi is Getting Pretty Cheap

As October came to a close yet another system was just spinning up, and didn’t take TD29 very long to morph into Tropical Storm Eta.  It was forecast to ping pong around the Caribbean before potentially turning north towards us….but as you can tell from the scattered model plots in the graphic below, they really have no clue where this one would end up going.  We’ll be monitoring closely.

The Early Track Forecasts for the Next Storm are Literally All Over the Place

And finally, to bring October to a proper close, we enjoyed a marina-style celebration of Halloween.  By 31-October our temps had moderated to a pleasant 80F, with a pleasant breeze and mostly clear skies. That allowed B-dock adults to gather for happy hour docktails, and then at sunset the youngsters in our little liveaboard community enjoyed a fun, albeit masked and socially distanced “Trick-or-Treat” experience.

Trick-or-Treating on the Docks at Legacy Harbour Marina

Afterword: As we went to press with this blog entry the latest tally of the US election results was still underway.  One candidate was lobbying to stop counting votes and declare himself the winner.  We suppose there's something to be said for being a consistent cheat.  Meanwhile the virus seemed to be exploding (again) nearly everywhere.  Be very careful out there.

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.
