Still Hard At It

The work on the boat goes on at a steady pace. The old saying that life is what happens to you when you are making plans is all too true. Our original plan when the boat was purchased was to be on our way to the Bahamas by now. Things obviously did not work out that way but maybe that is not such a bad thing. In as great condition as the boat was when we bought her, she is in need of a LOT of work before she is able to comfortably do any long distance cruising. It appears that we will be here in Beaufort until at the very least next year. That might seem like a long time but with the work we need to do and the need to raise enough money to pay for all of the improvements and keep the cruising kitty intact, the time will fly. When we left on our previous boat to cruise from Houston to come here, it might have been the first time the boat was completely equipped and tested and we were not still working on projects as we headed out. It was a nice change from the past and we would very much like for this boat to be in that condition when we next leave the dock for a while.



The refinishing of the teak is moving along albeit slowly. The previous owner, in an effort to protect the wood used a deck stain on all of the exterior teak. It has been harder to remove the stain than it would have been to just sand the wood if left alone. But we, or should I say, the teak master is making nice progress. We are adding some interior lights at the entry to the forward and aft cabins so we don't have to feel our way around in the dark to turn on the cabin lights. We are using LEDs so that we can use them at anchor since they draw very little in the way of amps. Caulking on the exterior is far from finished but the areas we believe leaked in the past have been done and we wait for the next rains to verify that. As we re-caulk we are also replacing all of the original fasteners which are all showing their age. Regarding leaks, the problem in the forward cabin caused the teak parquet to separate from the sub floor. The sub floor itself is still intact so removal of the parquet, sealing the sub floor with West System, then re-gluing the parquet with epoxy should take care of the problem for some time to come. We also took advantage of the repair to refinish the parquet in the forward cabin. Eventually we will get to all of the flooring. We choose Ultimate Sole to do the refinishing ( http://www.ultimatesole.com/index.asp?ID=2) because of our past experience with the product and the fact that even with a high gloss finish it is not as slippery as most other high gloss finishes.

Our water tanks consist of two 75 gallon stainless steel tanks in the stern of the boat. They are connected together by a crossover pipe at the bottom so both tanks maintain the same level. Filling the tanks meant moving the hose back and forth between the two tanks until they were both full. It is not that difficult but I am always looking for a better way to do things. The solution turned out to be very simple. I went to the local hardware store and purchased a drinking grade 25 foot RV water hose and three female connectors and one male connector. Total cost was $27.24 and about 20 minutes of my time. For our purposes the rig consists of a short piece of hose about 3 feet long with a male connector on one end and a female connector on the other. This is attached to a Y valve that has a cut off in each leg. This is commonly used to connect two garden hoses to a single hose bib. I then cut two more lengths of the hose about 4 feet long and attached a female connector on one end of each. These two hoses are attached to the Y valve and the ends with no connectors can be placed into each of my water tank deck fills. Once the hose is turned on, both tanks are filled at the same time and with the same water flow. With the cut offs in the Y valve one hose can be turned off if one tank fills faster that the other or both can be cut off when the tanks are full. For folks with deck fills on opposite sides of the cabin trunk, you can still use this system, just attach longer pieces of hose off the Y valve to run down the deck from the bow on each side or adjust to where ever your deck fills are.

Cleaning up wiring and just cleaning up the boat fills a lot of time in between these little project. We just found out we have cable TV on the dock but the boat never had a inlet for phone or cable TV so that means an inlet will get installed and the cable will need to be run from the inlet to the entertainment center. So that just got added to the list. And oh what a list it is, so stay tuned.

Simple and Inexpensive WiFi

Part 1.

More and more cruisers, be they just weekenders or long distance travelers, are wrestling with the issues of staying connected and yes, I mean to the internet. My first boat had nothing more than a VHF radio and I was able to sail from the US mainland to Bermuda. Later on as the boats got larger and communications improved, a marine SSB radio was added. Then a famous person, I can’t remember who, invented the internet. With that, the ease of email crept into our lives and grew like a weed along the banks of some of the rivers we have traveled. We were hooked and began the search for the latest and greatest technology. Our first device was a hand held unit that was called Pocketmail and needed to be held up to a phone after calling a special number and it would send and receive your emails. It was a pretty neat device and very popular in the cruising circles. Next we added a Pactor modem to our SSB radio and after acquiring a Ham license, used the Winlink system to send and receive email and get that all important weather information. We still have and use extensively the Winlink system. But the more we were exposed to the internet itself, the more important it became and the more functional we found it to gather information on weather, emails and the areas we were traveling- something the Winlink could not do for us.



With the availability of WiFi hotspots to connect to, the possibilities grew considerably. Again, we would have to evaluate our needs and how to meet those needs with the changing technology. For the cruiser today there are now some great choices depending on the areas you plan to cruise, the space aboard and power requirements for additional equipment and that all important dent in the monthly cruising budget. Starting at the high end is a satellite system that can be used on a large part of the planet, even the watery parts. A satellite dish mounted inside a dome and engineered to track and hold the satellites position will give full access to the internet and all it contains.



If coastal cruising is in your plans, or even some of the more developed islands, than another option is a wireless phone card modem attached to your computer that will connect and receive anywhere you can get a cell phone signal from your provider. For simple email via text format only a satellite phone will provide this almost anywhere in the world although some folks are finding the coverage is spotty on some oceans. Finally, many cruisers are finding that with a computer that has WiFi capabilities and a device to reach out and grab those free WiFi signals found in more and more locations the costs are relatively low and the installation is fairly easy. Most importantly, after that purchase of equipment, access is free. There are pay services sprouting all along the coast that will provide access via this same system in larger ports. After considerable research we decided on the WiFi method with the free access. Free is always good for most cruisers. Once the decision was made on the what, we now needed to decide on the how.



It is no surprise the internet provided us with the answers. Research, research, research, using mostly cruising website that we have found in the past are frequented by actual cruisers willing to share their knowledge and experience. Two such sites are the SSCA Discussion Board and the great site at Cruisersforum.com. A common name came up over and over again with lots of positive input. Some cruisers also had their own way of putting the system together to improve performance and protect the equipment. We decided on a WiFi unit Made by Senao. The Engenius UEB362 EXT long range USB adapter (now updated to the EUB9603H) was recommended over and over again. Another key piece of the equipment is the antenna. Like any over the air receiver, the antenna can mean the difference between success and failure. We try and match our equipment as much as possible and decided in the Engenius 8db outdoor omni-directional antenna. A small pigtail adapter is needed to attach the much larger antenna to the unit. Your choices will be either omni-directional or directional. The omni-directional will look like the antenna you are used to seeing and the directional antenna will look sort of like a small dish that needs to be aimed directly at the WiFi access point. This works great at the docks but swinging on the anchor as most of us do would present too much of a challenge. The omni-directional does not care whether the boat is swinging so naturally that was our choice.



Having the antenna be weatherproof and outdoor suited is a big plus. Keep in mind these units are not designed to be used in the manner we have planned. The unit itself is not waterproof and the attached antenna is very small. But it is removable and many of these units on the market do not have a removable antenna. That ability limits or extends the range of the unit. We would need to either find a way to weatherproof the unit or move it in and out as needed to keep it dry. Both will work but we prefer to keep it outside while underway since we can often connect as we pass a hotspot without stopping. The final short coming of the unit as is was the short cord that attaches the unit via USB to the computer. It is only about three or four feet long and won’t get it outside unless the computer is outside and we did not want to do that for obvious reasons. But this too is easy to overcome.



Once we had the adapter and antenna in hand, the search for the additional bits and pieces began. We found that a 6X6 plastic electrical box with no holes in it would make a very good weatherproof box to mount the adapter. We purchase a weatherproof gland to pass the cable through and some coax sealer. We found we would need an “active” USB extension cable to get the unit high enough to have some range with it. Having an active cable is important because the unit gets its power from the computer via the USB cable. Be sure it is NOT a passive cable or it will not work. We have received reports that we should not exceed 20 feet for the extension cable but others might find longer will work. Finally, a bit of silicon caulk to seal everything rounds out the material.



The electrical box has plenty of room to mount everything inside and a smaller box will probably work but this was what we used. First you will need to drill a hole in the top to accept the antenna. It slides into the hole and a locking nut on the inside holds it just fine. The hole around the outside and inside should be sealed with a bead of silicone caulk. Next a hole should be drilled into the bottom to accept the weatherproof cable gland and also sealed. Remove the antenna that comes on the unit and use some double stick tape to hold the unit on the back of the box. The first thing we noticed with this unit was its size. It is not much larger than a business card. Before mounting it, attach the pigtail to the antenna and the unit itself. Pass the USB cable from the unit through the hole in the bottom and attach the weatherproofing portion of the cable gland and add some silicone sealer to help keep moisture out. Once all of this is finished, add silicone sealer around the perimeter of the box and attach the cover. The box we purchased had tabs on the corners with holes in them so we could attach different methods of hanging it. We plugged the 20 foot active USB extension cable to the one that is attached to the adapter. Here is where the coax seal comes in and makes the plugs completely waterproof where they are joined together. The seal is sticky and stays that way so be sure and cover it with electrical tape to keep it from sticking to everything (and everyone) it comes in contact with. You will be almost finished but there is one final step before you start connecting.



Before you plug in the unit, you will need to set it up on your computer. There are two methods to do this. The adapter comes with a CD with the required drivers and a program to help make your connections. If your computer is not WiFi capable you will need to install this program. If it is WiFi capable you have a choice. In our research many complained about problems using the program that came with the adapter. Your Windows operating system has a service called Windows Zero Configuration which will manage all of your WiFi connections. Many users, including ourselves, let Windows handle the WiFi with few issues, but the drivers for the adapter need to be installed. Simple - go to the disk, find a folder called drivers, open it and click on set up. It will install the drivers and ask you to plug in the unit. Once installed you will need to restart the computer, and that is should be about it. It should not take a whole lot longer than it did to read this article. Once everything is done and the unit is hung as high as you can get it with the cable attached to your computer, you will be connecting any time an open access point is within range. We have been truly amazed at the range of this set-up and how well it performs.

And now for our total expenditures:

Engenius EUB-362-EXT $45.50  (now updated to the EUB9603H)
Engenius EAG-2408 Outdoor antenna $24.99
CA100 –NM-RSMAM-12 RPSMA Male to N Male 12” cable $9.00
RJ45-FT Feed-thru adapter $1.10
104 Coax seal $2.29
Plastic Junction box with lid $12.16
20’ Male to Female USB active extension cable $12.99
Silicone caulk $5.95

Total cost: $113.98

We did find a couple of sites on the internet that sell these same units already made up for a bit more money, but we like to build these things and install them ourselves. We get not only the feeling of accomplishment, but the knowledge that the parts are of the quality we expect. This has been a great addition to our equipment list and if your needs will be filled with this kind of set up, you will surfing before you know it.

And The Beat Goes On

We have just had a couple of days of some pretty steady rains and found out we have not yet resolved all of our water leaks. The good news is that the serious ones have not resurfaced and it appears that right now we have only one to deal with. This one is in the forward cabin coming from the area of the cap rail. We are assuming this is coming from the stanchion bases since that is one area we have not sealed yet, so that is priority since rain is forecast again in a few days. After removing fasteners from the bases we are pretty certain this is our problem. The old screws are loose, rusted and broken and most are the originals. As is our usual deck repair, once the fasteners are removed we fill the holes with a thickened mix of West System epoxy. This seals the wood around the holes and perhaps some of the spaces where the water can pass through. Prior to filling anything the areas are taped well to make a cleaner, neater job when it is finished. A small hardwood dowel is inserted in the holes to give the new fasteners something to grab to. A healthy dose of caulk is injected into the hole and the fasteners are also coated with caulk. I am using stainless steel lag bolts in place of the old slotted screws. This allows me to tighten them more than with a screw driver. One of the little tricks is to not tighten too much and allow the caulk to dry. Then come back and tighten the fasteners later and the dried caulk will actually form a gasket. The tape is also removed after the caulk is dry and the caulk is trimmed to make a finished look. The radical change in fasteners also makes it very apparent which ones still need to be replaced.

One of the more fun projects is completed and that is the installation of the new stereo system and six disc CD changer. We have used Clarion products in the past with good results and performance so stayed with what we know. The hard part was getting the panel cut to flush mount the CD changer since they are not designed for this. The Clarion also allows us to run audio cables to it and connect those from the output of the TV. With four new stereo speakers mounted forward and aft in the main cabin we now have surround sound from the TV and DVD player without the large entertainment systems taking up valuable space. We found marine stereo speakers by Dual at Boaters World at a great price and they sound fantastic. Now the TV, DVD player, CD changer and of course the stereo itself are all together. With the DirectTV satellite system we also have satellite radio which now can be sent through the stereo.

The teak master is also starting on all of the outside teak, and there is lots of it. The former owners put a deck stain on all of the teak and while this did protect it we need to remove it all for the refinishing process. We also had lots of exterior teak on our previous boat and have been down the varnishing and other finishes path for a lot of years. We have recently settled on Sikkens Cetol and don't regret it one bit. It is much, much easier to apply and maintain than varnish, looks great using the Natural Teak and lasts much longer than varnish in the tropics. Adding maintenance coats is a snap. But we are just in the beginning stages.

Battery charging has been on my mind of late and charging the starting battery without overcharging has been a consideration. I have decided to use the Xantrex Echo Charger for the starting battery, rather than try and connect it to the house charger. This is a simple connection from the house bank to the starting battery and it senses when the starting battery needs a charge and borrows it from the house bank charger or alternator. Otherwise the house charger and alternator are connected to and charge the house bank. It solves my charging problems and does a very efficient job.

The windlass is also in the starting phase. It is mounted on the bow platform but I still need to do the wiring and install switches, etc. The water leaks have caused a few things to be put on hold until they are resolved but the windlass will be a pretty straight forward install. We will also need to upgrade our anchor rode and chain but all things will get done eventually.
