A Garden At Sea Again

So Much Growth, We Brought Out The Big Guns For Harvesting

Admiral Ley has a well trained green thumb. As I described here last year, at every opportunity she grows a range of herbs and salad greens that add flavour and zest to our diet onboard.

A couple of months back she re-started our garden, again using the Greensmart self-watering pot that has been so productive for us. Once again, it's taken off, growing like crazy. We're often able to give away fresh herbs to cruising friends.

Right now she's growing Basil, Cilantro (Corriander), Italian Parsley, mixed Lettuce, Arugula and Rosemary. All this in a tub that measures just 570x400mm.

Great Guana Key, Bahamas

Community Fish Cleaning Action At Great Guana Cay
Sunshine, clear waters, fresh fish, friendly people - it doesn't get much better. Unless of course you also like messing around in boats, in which case all your dreams can come true here at Great Guana Cay in the Bahamas. I guess it must be a little frantic at peak tourist season, but right now its extra laid back and friendly. We arrived here yesterday after a quick 3 hour passage from Green Turtle Cay, and have settled into the anchorage to sit out the front that is expected later today.  We're in 3 meters of water with 27 meters of chain out, so we're not planning on going anywhere soon.

This morning we took the (fast) ferry 16nm to Marsh Harbor, where the Admiral found a hair dresser and we both searched the hardware and marine stores for parts we needed. That search turned up nothing of value, so we headed back to Great Guana in the early afternoon. This afternoon, before the weather deteriorated, we spent a few minutes testing our new aerial camera system, with great results. Click the play button below to view.

So, Which Ball Valves Are You Using ?

Philmac Ball Valves On Our Seawater Manifold
My story on ball valve replacement at sea (read it here) lead predictably to the question of ball valve construction. Are you a traditional bronze kind of sailor? Or maybe you like stainless steel? Or just maybe you've converted to the newer industrial plastics, made with glass reinforced PVC or Nylon?

On Crystal Blues we love the industrial plastic valves, and have used Philmac ball valves for almost 20 years. These are built for the industrial process and agriculture industries, are tough as nails and (the best part) are cheaper than all those products that have the word marine included in the product description.... still, I understand the Philmac valves are approved for use on commercial vessels in commercial survey in Australia and New Zealand.

Engineered plastic valves are light, strong, do not corrode and won't conduct electricity, all properties that I love. Nowadays there is a new and I believe even higher quality product available - made from glass reinforced PVC. New Zealand company TruDesign make a superb range of tough, precision plastic skin fittings, valves and plumbing components specifically for the marine market. These are sold all over the world, and have certifications from Bureaux Veritas, ABYC, CE and ISO. These are the valves and fittings that will be used on Crystal Blues in the future.

Or Are You Using "Marelon" ?

Glass reinforced plastic valves and fittings are also made using Marelon, principally marketed in the USA by Forespar. Unfortunately these valves have experienced well publicized failures over many years. Marelon is a version of Dupont Zytel, a glass reinforced form of Nylon, a fine structural material, but perhaps not best suited to making marine ball valves, as the base material is weakened by immersion over long periods.  Read The Discussions Here and buyer beware.

We won't use the Forespar Marelon valves. I should also say that the Forespar Marelon toilet waste diverter valves we purchased never worked properly - the closed outlet always leaked slightly, meaning the holding tank had to be emptied periodically even when not being used.

They were not fit for purpose in my experience. That was an expensive mistake, rectified by refitting with TruDesign diverter valves.

At Last, Bahamas Sunshine ...

New Plymouth Town, Green Turtle Cay
Crystal Blues finally escaped the freezing conditions and weather bombs of the US East Coast, clearing from Palm Beach and heading east across the Gulf Stream to the shallow banks that make up most of the Bahamas Island group. In 8 hours we were across the stream and moved on to the banks, and 8 hours later we were at Great Sale Cay, anchored in 3 meters of water for a peaceful evening.

The Admiral In The Loyalist Sculpture Garden
We cleared customs and immigration at Grand Cay, and sheltered there for a few days, before heading East and South around the top of the Abacos island chain.

Three days ago we anchored at Green Turtle Cay and settled for a while, enjoying the (finally) calm weather and the friendly village atmosphere in New Plymouth town.

This is a community that dates back to the 1780's, when British loyalists departed the United States after the war of independence and resettled here. The English language is different here, and the folks are proud of their heritage.

The waters are clear, and there is a decent tourism industry based around visiting boats and resorts. The famous Green Turtle Club provides marina, restaurant and bar services, competing with the nearby Bluff House to woo visiting boats and crews.

Perfectly positioned on the sea of Abaco, between the outer reef and Great Abaco Island, this is one of a string of barrier islands that really make you think about staying forever.

Of course this is winter, the low season, and the marinas are generally fairly empty, though there are plenty of cruising boats around, principally from the USA with a few from Canada. Winter weather brings a series of northerly and north easterly blows to this region, each of which seems to last four or five days. This morning, with another 35 knot blow on the way, we departed Green Turtle and moved further south to Great Guana Cay, where we will shelter for the next five days.

Changing A Thru Hull / Ball Valve At Sea

New Valve Going On, No Water Enters the Boat

We've done this a couple of times now, and it's a really simple and fast maintenance job. Finding a dripping leak in a ball valve on the engine sea water inlet, we investigated and found it was seeping through the seal to the handle. It had given us 15 years of service, so I was happy to replace it. We located the spares we carry and selected the right size - 1.25" in this case.

Next we needed a diver, and in chilly St. Augustine that was not going to be the Admiral. No way said she! A call to the local cruiser's net identified a willing local, so we scheduled the job for the next day at slack tide. Note that Crystal Blues has skin fittings (thru hulls) with stand pipes that are threaded, to allow the ball valves to be screwed on and off, without actually effecting the skin fitting.

Diver Ryan arrived right on time, and as he prepared his gear and suited up I started on my own work sequence :

- Close the faulty valve and loosen the hose clamps on the hose connected to it

Trusty Toilet Plunger
- With the hose clamps out of the way the hose tail (hose barb) is unscrewed from the valve. It rotates easily inside the hose, meaning you don't ever have to fight to actually get the hose off the hose tail. This is made easier if you always apply a little silicone sealant to the hose tail during assembly, before sliding the hose over it.

- Once the hose tail is disconnected the action begins - Ryan the diver enters the water with our trusty toilet plunger and holds it over the water entry point. He taps three times on the hull to signal he's ready, and I open the ball valve - voila, just a tiny amount of water enters the boat, before the pressure differential forces the plunger tightly against the hull and seals the entry.

- Unscrew the old ball valve, clean up the threads on the stand pipe, apply new PTFE tape and then screw on the new valve. Close the valve, tap three times on the hull and the diver removes the plunger. Simple!

- Some time later I re-attached the hose tail and re-fastened the hose clamps. Job done.

While many older boats still have skin fittings that incorporate the valve, many newer vessels are built with separate components which allows this process to work just fine. From my perspective, $80 for a diver for 30 minutes is a lot better than $800 for a haul out, just to change a ball valve.

A New Year Begins, New Destinations Await

You know you're getting older when your favorite local radio station is called The Real Oldies. Whatever happened to K-Rock, Planet Rock, or KIISS and the like?  They all drifted into pop sameness, or repetitive rapping, is what happened..... and I stopped listening.

Here in Florida we had a great Christmas, listening to The Real Oldies on the rental car radio, pulling together the supplies and parts we needed and then celebrating with friends at Hobe Sound, north of Palm Beach.

George & Nancy Marvin, OCC Port Officers for the region, kindly invited us to share Christmas Eve and Christmas Day Luncheon with them - a fine group of cruisers were there, so spirits were high and endless dreams and lies circulated the table.

George & Nancy also kindly acted as a delivery point for our many parcels in the weeks before and after Christmas. Once those goodies were in hand we settled down to a sequence of repairs and service jobs onboard Crystal Blues.

The toughest project was replacing the heater hoses that snake their way through the boat from the engine to the hot water service. The old hose had been installed 12 years ago and was starting to crack - we'd found and repaired two leaks in the past 6 months.

So out it came, which took a day, and then the new silicone rubber hose went in, which took a couple of days - there is about 70 feet of hose in the circuit.  For good measure we flushed and cleaned the cooling circuit in the engine, and replaced the coolant in the system.

Both the Northern Lights genset and the Cummins main engine were due for injector servicing, so we gave both engines a treat and installed new (actually re-built) injectors. Both machines are running silky smooth now, aided by the recent valve lash adjustment - you really can tell the difference.

The Cummins was also rewarded with a new Walker AirSep Filter system, the original item having passed it's use-by date - 12 years was a good run. All in all the boat did real well in the Christmas gift department.

As to those radio stations, we also spent a day installing a new FM radio antenna connection - then scrolled right past the local spanish and rock / pop channels to settle on Legends Radio, a local jazz oriented station. Bliss.

Hopefully we'll be well ahead on the service and maintenance items when we leave here, and can spend time relaxing in the Bahamas soon. The cold weather that is impacting us should pass in a couple of days, and we're hoping for a clear weather window early next week for passage to the Bahamas.

Freezing In Florida

Welcome to Florida, where it's so cold that it's raining Iguanas - see the story here.

We stopped our voyage south at Palm Beach in central Florida, entering the harbor at Lake Worth inlet and anchoring off the friendly Palm Beach Sailing Club. Over Christmas and New Year the weather was mild, warm and sunny, so we set about completing a series of maintenance and service jobs, preparing for our crossing to the Bahamas. Immediately after New Year the scene changed, with north Florida receiving (almost unheard of) snowfalls and freezing temperatures.

Last night we had a minimum of 3degC. here, and tonight it will be 4degC. Florida temperatures in the winter normally average between 18 and 21 degC. Our friends all the way up the East coast are experiencing sub-zero temperatures and snow falls, while Chesapeake Bay is closed to shipping and harbors are freezing over even in the Carolinas. The weather guru's are calling it a "bomb cyclone", and it appears to be strengthening at it runs north up the coast. In reality we only caught the southern edge of this astounding weather event.

Of course we had just finished packing and stowing all our warm clothing, winter duvets and blankets - who needs those in Florida, right? Right. Yesterday we broke out the winter clothing and bedding again. With luck we'll escape to warmer weather in the Bahamas within a few days.
