 I have a Yanmar 4JH2DTE in my boat and I don’t seem to be getting the power I am used to above 2,400 rpm. I checked the fuel filters and they seem OK. What else should I check?

Can I use a regular computer monitor? http://sailingmagazine.net/article-1792-can-i-use-a-regular-computer-monitor.html Can I use a regular computer monitor?

 We’ve used an Argonaut T-Flex marine monitor on our boat for more than 15 years. It worked great because it allowed us to keep the laptop running the navigation software safely in the nav desk and it operated with a wireless mouse. We could see it even with sun glare and we never had to worry about power spikes or water damage if a wave came down the comp...

Why are my halyards fraying? http://sailingmagazine.net/article-1780-why-are-my-halyards-fraying.html Why are my halyards fraying?

 My Tayana 48 came with wire and rope halyards and as part of my refitting efforts I replaced them with high-quality Dyneema double braid last summer. After wintering in the Caribbean on the boat and bringing the boat back this spring, I found that the cover on a couple halyards and the topping lift has worn through. I bought what I thought was good cordage,...

How do I track my boat's systems? http://sailingmagazine.net/article-1763-how-do-i-track-my-boats-systems.html How do I track my boat's systems?

 I’m the kind of person who likes to know how things work and a few systems on my boat have me stymied. A few years ago I installed a Frigoboat keel-cooled refrigerator. It works great, but I am trying to figure how many times per day it runs and for how long. It’s so quiet that I can hardly tell when it is running....

How do I install an AIS antenna? http://sailingmagazine.net/article-1741-how-do-i-install-an-ais-antenna.html How do I install an AIS antenna?

 I am adding an AIS transceiver to my boat. After a few close calls, I decided that not only do I want to know where other boats are, I’d like them to be able to see me as well. It looks like the AIS will work well with my chartplotter but I don’t know what I’m supposed to be doing with the antenna. I’d appreciate your guidance.

Why does the tachometer read high? http://sailingmagazine.net/article-1714-why-does-the-tachometer-read-high.html Why does the tachometer read high?

 I just bought a used Catalina 36 MkII. I’m thrilled with the boat but I have an issue that came up during the survey that I’d like to resolve. The tachometer appears to read high. The boat idles at the proper speed, but the tachometer reads more than 1,000 rpm. A similar problem occurs at cruising speed as well. I discussed it with the surveyor and he ...

How long should running rigging be? http://sailingmagazine.net/article-1649-how-long-should-running-rigging-be.html How long should running rigging be?

My Jeanneau Sun Odyssey 40 came with running rigging lines that all seemed needlessly long. The extra line adds to the difficulty of housekeeping, and in rough going sometimes creates a mess under foot that creates what I would call a hazard.  After a few years, I cut all lines to their longest useful length.
