Paddling in the mourning
It is the first day in over 3 months where I cannot enter the beaver forest. The water has dropped a few inches this week, the narrow gaps that I had squeezed through are even thinner, the shallow spots where I just cleared beaver felled trees are now land bridges. I can come back in nine months.

I stop among the lotus pads - something I more often complain about because they restrict my paddling during the summer, but today the pads are alive, or I should say, today I notice how alive the pads are. Bees move among the blossoms and rest on the pads themselves, dragonflies are all around, and something stirs under the pads as I move. I don't mind them much today.

The surviving female adult eagle from the south nest flies by. Her mate was killed yesterday by a vehicle on the stupid bridge that passes through this beautiful area, a dead scar, an obscene gesture of progress. I have no response to it other than my own verbal obscenities. So, the sunny warm day has a certain somberness to it. I saw their eaglet in a tree two days ago... "so it goes".

Harvesting Gum for Sealing the Canoe
While taking a break from the monotony of lashing the gunwales, I've been eagerly collecting any pine or spruce gum oozing from trees in my area. At first the process was frustating as I could only find tiny droplets of gum that didn't seem worth the effort. But after I started paying closer attention, I began noticing several large gobs of gum on these trees, typically emanating from below a branch wound.
The most gracious source was a white pine under which we BBQ all the time! A copious amount of gum had accumulated under a branch wound and had already begun to dry out and turn grey. Using an old broken knife, I harvested the gum into a can and scraped off other sources

Gob of gum; Harvesting with an old knife
When I started harvesting from these sources, I would notice a large grub wiggling around in the bark. Further research has pointed out that I've been getting assistance from the Pitch Mass Borer (Synanthedon pini), a type of moth that deposits eggs on the bark of the host pines and spruces during June and July. The larvae bore in the inner bark and sap wood excavating tunnels and cause copious amounts of sap to flow as a defense mechanism. Usually a single larva is found in one glob and don't damage tree extensively.
Apparently removing the larva causes the wound to seal off completely and stop flowing so I've been careful to ensure that I don't kill the delicate larvae while also leaving some protective gum on the wound as well. Afterall, these little guys have made my harvesting sufficient quantities of gum much easier and the trees are supplying me with a fantastic waterproof sealant.
At anyrate, with all plenty of pines and spruce in the vicinity that have been trimmed for landscaping purposes, I've been able to collect a whopping load of gum. I ended up transferring all the collected stuff into a plastic bag and then stuffed it into a 1kg tub (formerly containing some fantastic Medjool Dates). After softening a bit in the summer sunshine, the 2 pounds or so of softened gum has taken on the shape of the container.

1 Kg of gum in the container
The unsightly mix needed to be filtered to remove bits of bark, soil, needles, and other debris. So I rigged up a cooking station with an Trangia alcohol stove, used an old cheapo pot to melt the gum and poured the resulting brew into an aluminum foil lined pan topped with a cheese cloth "filter". The pitch melted easy enough into a bubbling brew and occasional flared up like a flambe so doing this outdoors with a lid nearby to smother the pot was a must. After thoroughly boiling to cook off the bulk of the pitch smell (apparently making the gum less brittle), it was poured into the cheesecloth and the clean gum squeezed. This required some quick work because the cooling gum would solidify rapidly.

The set-up; Melting globs of gum
To reduce the extreme stickiness of the gum and limit the mess, I put the pan into the freezer for a while and that allowed the resin to break off the aluminum foil quite nicely. The chunks were then stored in a zip lock bag. After repeating this process a few times, I ended up with about 500 grams of purified resin (from the original 1kg amount). This isn't enough to seal the boat so I've been actively collecting more gum from any and trees I come across (eliciting strage looks from passers by).

I also found that the cotton cheesecloth tended to trap too much liquid gum, so my filtered yield wasn't as much as I had hoped. Both Jim Miller's DVD and Cesar's Bark Canoe video show the gum filtered with a burlap bag whose woven fabric seems to allow much more liquid gum seepage. After searching for burlap bags in vain, I posted an ad on Toronto's Freecycle and Bill responded to me request with plenty of burlap bags. I intend to use this with the next batch of gum preparation and expect to get better results. Thanks Bill!

Mapping the East River in My Head
I ask S where she wants to go. I have three new rivers for her to see. They are all worthwhile, and all a bit different. One is freshwater with forests and meadows and lots of tight meanders. Another is tidal, but above the brackish water, and well treed with lots of shade for a hot day. The last is tidal and open land starting near the sea, but the bird life is excellent - the East River.
We set out from the state launch on a long sand point that is way too exposed for the dozen houses that are built on it. The low tidal flats marsh has the short variety of spartina grass, the kind that prefers places where it doesn't get inundated with every high tide, only with the highest of high tides. The willets and osprey are active, and when we get upstream to the second osprey box, which is well back from the river, we spot 5 great egrets and eight glossy ibises all in one small area. The sparrow counting team is on the opposite bank and they report a slow day, only six of the sparrows that they are counting in three hours.
| Glossy Ibises |
The tide is near high and the current in the river is slack. The ocean wind pushes us upstream when the river hasn't turned to one side or the other. We notice that the river changes character with each bridge. Passing under the railroad bridge, the ocean tidal flats give way to a wide marsh valley that is constrained by rising forest lands. Passing under the highway bridge, the valley narrows more and the surrounding land rises higher. The willets disappear and the singing of marsh wrens dominates.

We continue pass my previous turn around point and come to a older stone bridge. The river valley narrows more, and now the osprey are gone, although they surely come here. I spot a stand of miniature cattails.
"We'll just go up to that flat topped tree and see what the river looks like." And, it looks like it will go a mile or a few farther as far as any canoe is concerned. But, we turn and paddle with the current, back into the ocean breeze when the river isn't turning to one side or the other.
We both agree that this might be the best tidal rivers that we have paddled in Connecticut.

Parsing the NMEA press release
![]() |
| SiRF Star III GPS and antenna |
To many NMEA 0183 is a slow and very simple serial data communications protocol that unlike NMEA 2000 can easily be parsed without any formal standards documentation. Verify this with 14 year old kid that can parse a 0183 sentence for his Ardunio project.
In today's world NMEA 0183 is very alive and doing well. It's not just for boats anymore. The sales of GPS chips are approaching an astounding one billion units per year driven by costs of about $3.00 for a GPS chip. Add a few more cents for the antenna and you're done. They live in tablets, laptops, smart phones, cars, airplanes, trucks, drones, watches and even inside people and pets. They provide timing synchronization for networks and systems, and provide data for precision farming.
Johnny Lindstrom is correct in his assertions. Unauthorized use of NMEA's 0183 standards and formats have become rampant. How did this happen and who are the possible culprits?

NMEA 0183 version 2.3 was released in 1997, and this is where I consider the modern NMEA 0183 era starting. The intervening 17 years saw few structural changes in these sentences making them very stable from a software developer's viewpoint.
The "How" part is NMEA's proprietary information up to around version 3.1 (2002) has been slowly leaked over the years and widely disseminated on the internet. This has been exacerbated by the sense of many that NMEA 0183 is older technology, so who would care? In reality it's more relevant and useful today than at any other time in it's past. In effect the combination of simple technology coupled with all of the technical information regarding the above sentences makes it available to anyone who desires to use it. Many do so without paying for it, and many commercial users may not even realize they should.
Who are the unlicensed users? In part only NMEA knows, but let's start by eliminating a lot of them. Here is the NMEA list of manufacturer codes, as of April 7 2014 and this list just a subset of licienced users. The implication is I hope, that they have purchased the standards or they wouldn't be on the list. In the case of the pictured SiRF GPS, the company appears twice. Once as SiRF technologies, and via an acquisition path as CSR.
There are two major groups to look at. Hardware manufacturers who use NMEA o183 I/O, and software developers. There are fuzzy areas and this can be a mixed bag of tricks. In one case I found a PC manufacturer who has a GPS chip set in their computer. The GPS chip set by itself doesn't speak NMEA, but a software driver update provided by the PC manufacturer translates the GPS data into NMEA sentences. It isn't clear if the software driver was actually written by the PC manufacturer, but even if it wasn't there are several free downloadable drivers that will do the same job.
Also on the hardware side of the fence are USB based GPS's for PC's. Most speak NMEA but in many cases you can't immediately tell whose technology is being used inside. Now include a huge number of offshore manufacturers that use NMEA 0183 in their products that may be effectively out of reach of any practical action at all.
There are many software products that use and parse NMEA 0183 as a data source. This includes GIS applications, generalized mapping programs, and analysis of GPS logging data to name a few. In addition there are literally hundreds of freeware applications that use NMEA 0183 formated data.
My advice to NMEA regarding its potential efforts to claw back 0183 standards revenue is to do it in a very careful and pragmatic way. There are endless scenarios with varying complexities and many yet to be answered questions to deal with. Look for the the blatant offenders that will make up the majority of the possible revenue, don't get greedy, and remember principles are always very costly. Chasing users who either don't have money, or don't make any money (freeware and open source projects) using NMEA 0183 is a fruitless and fiscally unproductive venture. Lastly gird your loins for the inevitable flak. You're going to get some and how you go about this will determine the amount of shrapnel you will have to deal with.

At the boat doctors in Palma Mallorca

http://dreamtimesail.blogspot.com.es/2012/10/ambushed-by-storm-gods-in-santa-ponsa.html
You can’t stay on the boat while it’s in the yard so we also had to get some accommodation in Palma. Luckily enough we were be able to get an apartment in the same block we’d stayed in right next to the Cathedral back in June. It was in a great location, extremely well priced with its own kitchen and laundry facilities and had excellent wifi. All of which certainly helped keep costs down.

Located in the centre of the old town, you enter by swinging open a huge wooden door and are instantly transported to a different world. It feels like you have walked into a theatrical Seventeenth Century Mallorca house. The bar is ornately decorated with huge candelabras, sculptures and large overflowing displays of fruit and vegetables in the entrance area. The wait staff flitting around are all dressed in crisp black trousers and starched white shirts separated by bright satin cummerbunds adding to the extremely impressive visual impact as you enter.

While Karen certainly enjoyed the rather out thereexhibition of works by revered local Mallorcan artist Miro, Rob was underwhelmed and far more impressed by the building itself as we made our way from gallery to gallery with each displaying different facets of both the new and old structures. As you wander the building you’re lead to different areas and levels winding your way up to the parapets of the old walls and then back down to the lowest floors.

However, early on the morning of Thursday September 27th we finally pointed Alcheringa’s bows away from Mallorca towards Ibiza, the first step on our 480 nautical mile trip to Gibraltar. We certainly hope that her Palma homing device is no longer operational. We’re kind of over it.
