Re: How many holes are too many? (Through hull)

AP has NMRA 0183 capable, not 2000.
Not need to have depth an. Speed immediately but plan to update soon.
Right now using Airmar transducer for ST60s. I wonder I can use them with bus box or something provide info both ST 60 instruments and autopilot.

I replaced my old paddle wheel with a B&G triducer when I went from analog to NMEA2000. Using that existing thru hull, I got temperature, analog speed, and depth. Then I closed off the old transducer thru hull.

That's nice, I will check it out if it compatible with NMEA 0183.
It will help a lot.

There is an 0183 adaptor you can plug into the 2000 network. You can connect to that.

Re: How many holes are too many? (Through hull)

The answer to you original question is is 'no more than the absolute minimum'. I can see why an autopilot may be able to use boat speed rather than SOG for greater accuracy but not anything else. What an earth does an AP want to know depth for, unless you run aground it is not going to effect steering!

Good, I will check it out,
Thanks again!

Maybe alert function for shallow water.
Does not want to be beached while sleeping.

Re: How many holes are too many? (Through hull)

For compatibility, contact some of the various instrument manufacturers, as I'm sure they've fielded most of these questions before. And tested out quite a few options in terms of mixing systems, & or brands, in order to see what works, & what doesn't.

Also some guys, racers especially, will re-write code so that various brands can be interfaced with one another. I see threads on this from time to time over on Sailing Anarchy. And there are also some guys there involved in pro racing, who'll have a lot more depth of knowledge on the subject. Along with possibly having developed much of the hardware & software from concept/inception.

Re: How many holes are too many? (Through hull)

With through hulls, generally less is more. I would however rather have ten through hulls that are easily accessible than five that are a real pain in the neck to get to. If you can't get to them easily you can't inspect them nor is one likely to close them after every use. If it is a simple five second task to open a door and close the through hull then one will inspect and close it every chance they can.


In your case two it sounds like you are not adding any through hulls. If you need to add two new ones you can seal up the old ones. Just make sure you have good access to them.

Thanks, I will do that. Ya, like NKE has their own # for Airmar products.

Yes, basically I do not want to make more holes, for now I may have to have one more.
