Lots of changes. Interested to hear how you make out with the new wheel and rudder.

"Starboard sure is handy stuff. When I did this project on the sailboat I used G10. It was much harder to work and fabricate, and I had to paint it. Starboard cuts like butter. Just be careful using a hole saw..."

What is the problem using a hole-saw on Starboard?

Those labels look great. What is the gadget you're using to make them?

It melts rather than cuts from the friction, making a real mess and requiring constant clearing of the teeth. And lots of edge cleaning afterwards.

Just a standard label maker. It's one of many good ideas from Compass Marine.

On another note, I was recently trying to troubleshoot an electrical problem with one of our apparatus here at work, and when I pulled the panel cover off I found that the entire wiring harness was built with wire that had been custom printed with the circuit label. It certainly makes it easy to trace wires through the harness.

When I got to the boatyard Thursday morning my boat wasn't where I left it. A good sign. The little travel lift dock got blown out by a big squid boat when he couldn't stop and crushed it, so the yard uses the big commercial lift for everything right now. So they used the little lift to move the trawler over to the big lift, and then used the big lift to launch. So they moved me over first thing.

I have been procrastinating dealing with my nasty bilge since day 1. But no longer. I used a cheap Harbor Freight transfer pump to pump it into a 5 gallon bucket. It was so nasty smelling I just tossed the pump in when I was done. I plan to go grab some elbow length gloves before scrubbing it.

The launch went as scheduled, and nothing leaked. The engine started right up so I buttoned everything up for the night. It felt great to finally be back in the water.

We did a sea trial Friday morning. I can't even begin to describe how much better the boat handles (but I'll try.) If you don't have a wedge on your rudder, do whatever it takes to add one!

First the new prop: the acceleration is impressive. Before, when I throttled up it would immediately make more noise and slowly add speed. Now the stern dips and the boat picks up speed smoothly. Slowing and stopping is night and day different. The first few times I goosed it in reverse I not only stopped but ended up drifting backwards. The engine hit WOT way too easily, with the tach reading 3100 RPM when I backed off, so I'll have to experiment with that later. Also, on the trip up it seemed that the top end speed was lower per RPM, but the trip was uphill and up current. "No honey, I HAVE to go out again to test the prop. The prop shop guy said so..." :-)

The biggest change was the addition of the rudder wedge. An amazing difference is that I now have steerage, without throttle input, at speeds above about 1.5 kn. The turning radius is much tighter, and I can manage the turn into my slip in a single smooth movement instead of needing to use reverse to help walk the stern.

Another pleasant surprise is the handling in reverse. I actually have some steerage in reverse. Above about a knot of speed I was able to turn to starboard (counter to my walk direction) with the throttle in reverse idle. I'll have to go practice more down at the side-tie, but I think it might be physically possible to back into my slip now. Another perfect excuse for boat time: handling practice.

Overall I'm super pleased with the results from the mechanical changes. The boat is much quieter and smoother, the shaft vibration is gone, and it handles like a completely different boat.

Made the trip back up from Ventura to SB on Friday morning. I didn't have time to finish the autopilot install, so I hand steered. It was significantly more pleasant with the revamped steering. I also played with the new electronics toys, and drove quite a bit from the flybridge. It's just so pleasant up there. Conditions were great, although it was pretty windy in SB when I arrived.

Leaving Ventura. Perfect weather.

Nearing Santa Barbara. The weather is still perfect. That isn't haze, it's smoke from the Rey fire.

The new radar worked great. I need to calibrate the heading sensor a few degrees to get the overlay dialed in, but it's already usable even without. I spent a little time playing with the various gain and noise reduction settings. I somehow managed not to take any pictures of it in action, but the color differentiation of return strength was nifty, although I don't think the 18" dome really has the angular resolution to make it a "must have" feature.

I didn't see any whales this time, and only two pods of dolphins. A few came over to say hello, but none really surfed the bow for long.

All said, another great trip and good time.

Sounds like everything worked out well although you may be a little under pitched on the prop. Have always liked a big rudder that makes things happen NOW.

It's been short of forever, but sometimes life just gets entertaining.

I've been using the trawler rather than working on it, as I've been doing projects on other boats. That and the boss declared a moratorium on tearing her up for the fall.

I had shoulder surgery, and it wasn't until this week that the doc has finally released me to start doing real stuff, as long as it isn't over my shoulder height, or heavier than 10 lbs. That limits the boat yoga...

But, I have at least been sitting on her a ton, which is nice. And we spent a spell back in Wyoming, where it got to -40F and snowed most of the time. So it was nice to get back and sit in a tshirt and shorts.

So I've been spending my downtime learning digital electronics, among other things. I've always kicked around building a custom boat monitoring / management system, so I figured this would be a good time. I decided to go with the low hanging fruit, so my first piece is a temperature and humidity sensor. The plan is to put several of these around various places (salon, cabins, engine room, bilge, flybridge, fridge.) There are lots of sensor options I've been considering, such as water level monitors, bilge pump counters (and duty cycle monitoring), heck, I even have a UV level sensor on the way (slow boat from China, literally.)

Version 1 functions so far. I have an upgrade with a tiny OLED screen that is working, but I'm in the middle of learning the screen drivers, so it doesn't display data properly yet. That'll be the next goal. I have set up a raspberry pi with a little touchscreen that will be the control head and primary display. They can talk over the wire now, but range is limited.

As soon as the doc clears me to start boatwork again I have one other boat to finish, and then it's back to work on the trawler. My goal is to back to trawler work by mid-march. Until then my plan is to build the boat monitoring system here at the house, and then install it this spring.

Thanks for following, folks. If there's interest, I'll document the building of the monitoring / management system.
