Making AT5 Files for Navico Chartplotters (Simrad, Lowrance and B&G)

September 8, 2018

We first started to use satellite images on openCPN about five years ago and what a difference they’ve made. I’ve dreamed about having those satellite images on my chartplotter, and with Navico chartplotters, it’s possible.

After a year of trial and error, I’ve finally, in my opinion, perfected my method of making satellite charts for our Simrad EVO3 chartplotters. I made a set of instructions for myself to remind me of the steps. Those instructions have now turned in to four videos and accompanying PDFs. I hope you’ll find these step-by-step tutorials on the method I’ve been using useful.

Here’s a link to the info on our Cruising Info pages.

And here’s an example of the result. Below is a screenshot from our chartplotter while we were going between reefs that Navionics doesn’t show with any reasonable accuracy.

Season in Fiji, Update

September 2, 2018

So here’s what we’ve been up to lately in Suva, Kadavu and Beqa, in pictures (and in no particular order)…

This has been a GREAT cruising season and there’s still so much time and so many places yet ahead. -Rich

Yogurt and Headsets, Thanks Lady Hawk!

August 31, 2018

While sitting out some higher winds here in Beqa, Fiji, we have a little time in our busy schedules (ha ha ha) to share a bit of information that was passed on to us by Sonya and Trevor on Lady Hawk in Tauranga, New Zealand. After all, for us, a big part of cruising is sharing.

They told us about making yogurt aboard. We’ve run in to a lot of cruisers that make yogurt, but somehow, Sonya made it more accessible. It’s now become an indispensable part of our cruising cuisine. Here’s how we make it.

We use an inexpensive yogurt maker, available in many grocery stores (even here in Fiji). We use this one from EasiYo.

Here’s the recipe that has evolved. (We’re really happy with the results.)

Step 1: Put two grotesquely heaping tablespoons of your previous batch of yogurt into the yogurt container as the “starter.” If we don’t have a previous batch, we make a batch from a pouch like this one.

Step 2: Add a little just slightly warm water, maybe an inch or so, and swirl it around to mix the yogurt and water together. (That’s 25 mm for you metric people, but you knew that, didn’t you?)

Step 3: Add 220 grams of powdered, full fat milk powder (update: now using 250 grams). We’re happy with the Pam’s brand we’ve been using but we’re running out so we tried another brand available here in Fiji and it’s just as good, if not a little better.

220 grams seems to be the magic number for us (update: now we’re using 250 grams). More powdered milk makes the yogurt thicker (like we like it), but too much makes it taste like powdered milk. We have an inexpensive digital scale we use to weigh out the powder. We zero it with the starter and water in the container.

Note: Maybe this should have been obvious to us, but it’s really hard to use this scale at sea! Before we leave on our next passage, we’ll weigh out zip-lock bags of powdered milk.

Step 4: Fill the yogurt container with warm water. Not hot. Just warm. Think really comfortable swimming pool temperature. Put the lid on and shake, shake, shake until all the milk powder is dissolved. Then top it up again with warm water and put the lid on (the water level goes down when the powdered milk mixes with water).

Update: Now we’re using cold water.

Step 5: Fill the EasiYo “thermos” with boiling water to the EasiYo suggested fill mark.

Step 6: Now the interesting part: We usually make our yogurt in the morning about 8 am. After making it, I set an alarm for 4 pm. At that point, I look at the yogurt. If it’s still a little runny, I leave it until we go to bed at about 8 pm (cruiser’s midnight!).

If it’s really runny, I dump out some water from the thermos and add boiling water to bring it back up to it’s recommended level and let it sit until bedtime.

I check it before we go to sleep. If it looks good when I tilt the container – if it looks thick enough, I put it in the refrigerator. If it’s still runny, I leave it overnight and put it in the refrigerator when I wake up.

With that procedure, I’m usually able to get nice, thick yogurt. Usually. Sometimes, it doesn’t thicken. If it’s really thin, like milk, I dump it and start again with a new package. I don’t know why the inconsistency. I don’t get too meticulous about the process. Maybe I should sterilize the container? Maybe boil the water I use to make the yogurt? But our results are good enough that it doesn’t seem worth the bother.

And when it’s right, which is most of the time, it’s amazing! It’s some of the best yogurt we’ve ever had! We add some walnut pieces and a drizzle of honey on top and it makes a great breakfast.

Update, April 30, 2020:

We’re now using 250 grams of powdered milk, mixing it with cold water (tap water).

We’ve found that if we shake the yogurt in the afternoon, before it gets thick, it will get really thick but slightly grainy, which is a good trade-off for us.

We’ll sometimes let the yogurt “cook” overnight to make it thicker. It’s a little more sour but a good sour taste, not too sour.

I’m no longer using the previous batch as a starter. I just buy yogurt starter at the health food store. It’s more consistent that way.

Occasionally, we’ll add a packet (50 grams) of dry coconut milk powder for really great coconut yogurt. That’s great with maple syrup and walnuts on it.

Headsets:

In the title I said “and Headsets.” Lady Hawk also recommend Sena “Marriage Saver” headsets. We bought a pair ($$$ expensive $$$) and wow, I can’t believe we’d lived without them! But that’s a subject for another blog post (coming soon). Hint: Sena may not be the best way to go.

Update, April 30, 2020:

Sena SUCKS! The quality is really poor and after a few months, one wouldn’t turn on at all. Before that, it would often quit after a few minutes of use and then not turn back on. There’s got to be a better product out there. I love the concept of the full-duplex headsets, and when they worked, there were great. They just didn’t work all that often.

Update: 

We made our own headsets, mostly. Here’s more about it.

Mantas at Vurolevu Island

August 19, 2018

Wow, Cyndi wanted to come to the Kadavu, Fiji area mainly to see manta rays and did she ever! She was with five at once at one point. I had one of the largest I’ve ever seen swim over me, slowly. So slowly that I was getting worried about getting to the surface to breathe. That was a first for me – manta-blocked ascent. There must be some kind of PADI class for that, don’t you think?

Here’s the video…

This seems to be a cleaning station rather than a location where they feed. The little rock with the most action was here: 18 51.533 S, 178 31.323 E. We went back several times and even saw one when we motored by on Legacy. They’re pretty easy to see from out of the water. Bombies just aren’t jet-black like this. When we got a little experience, we’d look for them from the dinghy and then jump in once we found one.

They weren’t exactly friendly, but the next best thing: unconcerned by our presence. I was worried that diving down would scare them away, but it didn’t (as you could see in the video). In fact, it seemed like they might have been a little curious as each time I rattled the dinghy anchor to get it set, one would show up. That could have been coincidence.

Sorry for the shaky camera work. That was Cyndi’s unstabilized Olympus Tough with some pretty heavy surface chop. We wish we’d had better visibility for the video, but oh well. We take what we can get.

Sometimes We Really DO Live the Dream!

August 19, 2018

Like today…

A very short while after we headed out of the bay, we caught this walu. Our second on this trip to Kadavu, and such great eating!

(I’m the one in the red shirt!)

After a short, 10 mile ride, we arrived at Vurolevu Island where we’d hoped to snorkel with manta rays again. We had five at once, including this guy who passed right over me. (Video coming soon.)

Snorkeling with manta rays at Vurolevu Island, Fiji.

Wow, this day deserved a toast! A champagne toast (followed by an amazing fresh-caught fish dinner).

And Nabouwalu Bay on Ono, where we ended up, was stunning!
