People can see your position and track, plus communicate with you in 2-way text message conversation. Lithium powered and uses Iridium satellites for worldwide coverage.

2. $250 Simrad HH36 VHF+DSC+GPS

Waterproof, floating, lithium powered VHF with DSC and GPS for short range communication plus navigation.

3. $250 McMurdo FastFind 220 GPS PLB

Distress beacon that works anywhere (except north/south poles) and is the smallest and lightest. Lithium battery operates for 24 hours as 406MHz Cospas Sarsat beacon + 121.5MHz homing beacon.

4. $200 Plastimo Iris 100 compass

This is both a hand bearing and a mounted steering compass.

5. $320 Lithium battery pack
Like this 120W one from Goal Zero:

6. $230 Solar panel for charging the Lithium pack
Like this 30W briefcase model from Goal Zero:

This puts the total investment on $1,550.- The Delorme SE requires a service plan which would be $25 a month for the kind of usage expected (distress function, unlimited tracking, 40 msgs per month plus $0.50 per extra message)
(I would use the $10/month safety plan because I don't message much).
This looks like a pretty decent array. But I would locate some KISS equipment for backups. Like a garmin 72 for lat/Lon that is plotted at least once a day onto paper chart. This will give you something to do and let you visualize your progress, thereby avoiding at least one hallucination- that you are not moving.

Also a separate waterproof VHF might be prudent.

The mcmurno is a PLB. For this crossing you really should spring for a full EPIRB.

Re: what is the best navigation system to install on a 16ft dinghy?

Let me give you a link to Human Edge Tech. This is a group that specialized exclusively in Nav/comms tech for exactly your sort of expedition. They will sell or rent most of the gear. They know exactly what works and what does not. They have outfitted a lot of the rowing and polar skiing/sled expeditions.

Here is a place to start, look up and see how Webb Chiles and many others made long trips Drascombe boats.

High tech navigation gear to be used in a low tech dinghy! This reminds of some places in the middle east...where people get around riding donkeys, and talking on a cell phone at the same time! Whatever works! Mauritz

How many GPS's to take? The Inreach SE has a GPS; the Simrad 36 has a GPS and both can be used to get the current position. The McMurdo PLB also has GPS but you can't use it without sending out a distress signal.

So no, I would not bring yet another GPS like the Garmin 72. Enough GPS'es. But yes a map for yourself is always cool.

I would also not bring two VHF radios. The Simrad HH36 is a fully waterproof handheld VHF.

The difference between this PLB and a full EPIRB is that the EPIRB has 24h extra transmit. But he can't wear it. Also, the PLB is a backup because the Delorme SE also has a distress button and is 2-way so it will be the primary method when it works (you want to know they got you covered, status updates etc.)

If you really want 48h EPIRB instead of 24h, then McMurdo has a bigger PLB that can do that. It is the FastFind MaxG which makes it equivalent to a full EPIRB except for the floating upright and strobe. I would opt for the small one, but here's the bigger version:

It is also double the price, $500.-

This also made me realize that I forgot the personal strobe which will fit inside the auto-inflatable lifevests ($20.- only):

Re: what is the best navigation system to install on a 16ft dinghy?

I would pop a handfull of AA batteries in a ziplock bag, and use a Garmin GPSmap76CSX or similar. Only turn it on every few hours to check your location. No biggie.

Yes, conversation always seems better when you look at who you're talking to.

Re: what is the best navigation system to install on a 16ft dinghy?

Just out of curiosity - what are the plans for food and water? One of the limitations of small boat sailing, no matter how seaworthy the boat and skipper are is storage. You don't want to weigh the boat down so much that it looses its seaworthiness. Before I got too far in planning, I would know exactly how much the boat can safely carry; water, food, tools, spare parts, etc. That would tell the "what I need" part of equation, only then would I start to thing about the "how".

Yup, you're right on the GPS. Three is definitely overkill, even for me... I'm just partial to the Garmin 7* series as they are built like brick outhouses. But push comes to shove, head west till ya hit land...

The spare VHF is the one you place in the bailout bag, the other one is on the deck.

Comes down to personal philosophy and how much room is has left for food, water and the two stoves.

Space for food and water?...how about fresh fish daily caught while sailing, of course...not to mention an occasional drop-in seagull, pelican or a cormorant! Yum! Life's good! Mauritz

Sort of a fishy-chicken flavor. If smoke cured, it is more like duck. Smoke cured with pepper, it reminds me of pastrami.
