    Basic Fuse Rating Question

    What is MRBF? ANL? So, if I have a fuse stamped 10A at 24V, it is going to blow at 5A at 12V?

    Basic Fuse Rating Question

    Thank you! I've long wondered about this. Why is it then that the voltage is stamped on the fuse along with the amperage?

    Basic Fuse Rating Question

    Hi; If a fuse is rated at 40 Amps at 24 Volts, what would it's rating be at 12 volts? Do you simply calculate it's resistance at 24 volts and then plug that into Ohm's law equation for 12 volts (ie is 20A at 12V)? Somehow doesn't make sense. Thanks.

    Basic Fuse rating question

    Hi; I often find fuses rated for a different voltage than 12 volts (ie 24volts or 32 volts.) Does the rated fuse amperage need to be converted to a 12 volt rating? Thanks.

    Not of concern; he will not be navigating; would just like to learn the principles and try using it. Will never be used on a body of water!

    Can anyone please recommend a decent sextant to purchase either metal or plastic; have a landlubber friend interested in astronomy who would like to purchase one and learn how to use it

    Seems like a lot of extra effort if you can use the SS ones on a piece of mahogany

    H34 cowl vents

    I spent forever trying to replace those and could not find any. Here's what I did. While I was at it I put baffles in the dorade box as there weren't any to prevent sideways water intake (although these cowls came with shut-off plates and insect screens that can be inserted.) Are actually much...

    Why You Should Inspect Your Foam Air Filter Element

    When I bought my '86 boat 5 years ago, the 3GM30 filter foam was gone with just the metal mesh remaining. Had obviously been ingested by the engine. This in a boat operating in a cold pristine environment with the boat stored every winter. When we tore apart the engine the following year (for a...

    Anyone use a CPAP when they anchor or moor out?

    You folks are terrific. I went about this all wrong and actually purchased an inverter etc. Going to go a different route and look into the portable 12 v machines for travel. I initially inquired with my doctor about 1 year ago and was told that the travel machines are far to noisy and will keep...
