Re: Furling boom

You mention any system can jam "if handled incorrectly". Just curious what steps are necessary to furl (or additionally furl) your in-boom furler when sailing deep off wind in 25 kts TWS in 8-10...

Re: Energy recovery from freewheeling prop

I was thinking a small clutch made for a tractor or piece of farm equipment. When I google "Prop Shaft Clutch" I get lots of hits.

Re: Energy recovery from freewheeling prop

I'm an electrical engineer, so please excuse me for venturing a comment on mechanical issues.

Have you not just described a clutch? They used to be on old cars.

Re: Energy recovery from freewheeling prop

I got rid of my maxprop as it was a continual maintenance headache, and put on a hefty three blade fixed prop, and let the shaft spin free under sail. Yanmar mandates this for my transmission.

Re: Catalina Morgan 45 Owners

For Catalina-Morgan 44/45 owners only: Rudder post flax is 3/8" and ideally uses three rings. I removed three, but was only able to get two new rings installed. I tried using 5/16" for the third...

Re: Navionics on a Win 11 PC using a VM?

Thx, I will take a look at this app. I wonder how it gets the Navionics charts? Maybe it is from Navionics?

BTW Navionics has a web page labeled Chart Viewer that is pretty nice. It has their...

Re: Navionics on a Win 11 PC using a VM?

I wondered about Playstore and how downloading and installing might go. Also, navigation seems very cpu-intensive and hence not likely to run well on a VM. Maybe there will be some more replies from...

Re: Catalina Morgan 45 Owners

Thanks. Measuring is worth a try, but it might be difficult - I am trying to avoid removing the quadrant. Might be time to buy some good calipers. Looks like it might be anywhere from 3/8" (used in...

Re: Catalina Morgan 45 Owners

I need to repack my rudder post stuffing box. Does anyone know the thickness of the flax used on that packing gland?

Re: Has boat insurance become so hard to find?

Does having a USCG 100 ton or six-pack ticket help get insurance for non-commercial operation and ownership of a private yacht? I was told by an agent it helps.



Could be an option for these...

Re: Beware: non-Yanmar impellers for 4JH series may not prime

I would like to see a picture of these pliers or a mfr PN. Extracting my impeller is one of the worst maintenance jobs on my boat. A real PITA. No room for the cleaver puller tool I bought -...

Re: Antenna TV on boats - the latest?

Cool Blue is the fridge. Got it from Rich at CruiseRO. It's a spillover setup - one compressor for the freezer and fridge box. Just put it in this year, DIY install, used it all summer. Draws 5 Amps...

Re: Antenna TV on boats - the latest?

Just curious, how much is "very little power" in watts? Maybe you have measured it?

For fun I looked up a new Vizio 43" Smart TV model V435M-K04. The Energy Guide says it uses 165 Kw/year at 5...

Re: Beware: non-Yanmar impellers for 4JH series may not prime

Yep, I learned this one the hard way. Use Yanmar. I also change the impeller every 300 h instead of the prescribed 600 h on my 4JHE. Also change them at least once each calendar year. I have been...

Re: Antenna TV on boats - the latest?

Well, to each his own. Enjoy that big screen.

By contrast, I don't need a TV (large or small, smart or dumb). It just takes up space, uses power, can't be used from anyplace on the boat. I don't...

Re: Antenna TV on boats - the latest?

It's very reasonable, but with my 2022-vintage Xantrex inverter, I see 25 watts of continuous power (2 amps) when running the inverter. If I try using the low power load-sense mode, the inverter...

Re: Antenna TV on boats - the latest?

Yes, these are cool devices. But, the main thing I want is antenna tv video. I can see everything on NMEA2K/Seatalk with my Raymarine Axiom.

Re: Antenna TV on boats - the latest?

Thanks, Richard, this is super valuable info and sounds like just what I need. I like the 12volts. Hope it is not too much power.
