Bahia Candeleros to Puerto Escondido

Q: How far north are you planning to go?

A: We doubt we’ll go farther north than Bahia de Los Angeles, but we have no firm plans.

Q: Have you fished? Is the sea warm?

A: We have not fished as of yet. The sea is about 84 degrees Fahrenheit. 

On Thursday, Eric ran the generator first thing in the morning, as he normally does. But this time, the batteries weren’t charging. Eric spent some time trouble-shooting the problem. We decided that we should head to the nearest marina, where it would be easier to diagnose and fix the problem. The batteries were still charging from the wind generator and the solar panels, and we have a small back up battery charger that was working, so this wasn’t an urgent issue for us. But charging the batteries with the full-size battery charger certainly makes life easier. 

We contacted the marina at Puerto Escondido, only 6 nm away, and made a reservation for Friday. We spent the rest of the day doing chores. In the afternoon, Eric got out the SNUBA gear so Christi could tackle her most arduous chore: cleaning the bottom.

It was particularly rocky in the water that day, so swimming took a lot of effort. She pooped out pretty fast. Eric used the SNUBA to make sure all was fine under the waterline, then he used it to adjust the flopper stopper. Eric and Keith played in the water for a while before we called it a day.

Bahia Falsa to La Paz

On Thursday afternoon, we’d attempted to go to La Paz via the road. Unfortunately, the logistics hadn’t worked out.  

Here are a couple sunrise photos from Friday:

Still wanting to go to La Paz, we started Friday morning off by planning the logistics to take Kosmos. Once we realized that conditions would be more favorable to travel in the early afternoon, we went back to the shallow nook and frolicked in the water some more. Oddly enough, there were less fish and birds than yesterday.

February 2019 Update on Us

Our big news is that we have moved back to San Diego! The San Francisco Bay Area was nice, and we did enjoy the boating up there, but we are deeply rooted in San Diego. Eric has returned to work at DivX, and he is excited by the new opportunities there. Keith is back at his former French language immersion school. We have mostly fallen back into our old routine. That includes helping our two remaining parents, who are both in their late 80s, very frail, and need a lot of help.

We returned in early January, when weather windows along the coast are few and far between. We lucked out and got an amazing weather window from San Francisco to San Diego in between two big weather systems. The window lasted three days, and we managed to get back into San Diego in (relatively) blazing fast 70 hours. Here is a photo of sea conditions:

Last year, we did a lot of work to Kosmos. We changed out both refrigerators and the washer/dryer, resealed the main engine keel cooler, installed a new wind sensor and display, installed a new inverter, got new bottom paint, and put Prop Speed on the keel coolers.

We’re hoping that life slows down for us soon so that we can find time to fix the technical issues with the blog site, as well as write posts about the work we’ve done to Kosmos and the places we’ve explored, both via boat and via land travel. Meanwhile, here is a pic from Angel Island, a small island park in the middle of the Bay:

Choosing a New Muffler and Removing the Old One

…continued from the Exhaust Wrap and Exhaust Leak (and Muffler) post. Here is what the muffler looked like when we took the exhaust wrap off:

Eric wanted to replace the old muffler with a stainless steel one. He contacted Nordhavn to see if the same muffler was made in stainless steel. It was, however, it was $1,400 vs $400 for the carbon steel version. But the bad news was that, while it wouldn’t rust as quickly as the carbon steel one, the stainless steel one was still prone to rusting, too. Hmmm… that didn’t sound good.

Eric talked to a few people and found out that Continue reading →

Exhaust Wrap and Exhaust Leak (and Muffler)

In early 2010, we knew we had an exhaust leak. Also, the shiny metallic coating on our exhaust wrap in the engine room was starting to disintegrate, regularly shedding small silver fragments all over the engine room.

Eric knew getting the exhaust wrap off to look for the leak would be be messy, since it was falling apart. Getting it back on would be difficult and even messier. We decided it was time to replace the wrap, and hired a professional to remove the old wrap, measure and fabricate new wrap, and install it. While the wrap was off, Eric could inspect the system and make the repair.
