Re: Shallow depth alarm

The Garmin 700 series has an output wire that will go low when the alarm is sounding. It is rated at 100ma max so I doubt you could drive a speaker from it but you could trip a relay that could drive the speaker.

Re: Top Speed?

Here are my measurements for a moderately heavily loaded :macx: with a BF40D (fuel injected). Bottom is clean but paint is a little rough. 12x10 3 blade Solas. Ballast is out, mast up, no jib, main under sail cover. No appreciable wind or chop. No current. Fresh water. Speed measured by GPS. Fuel fl...

Oops. Looks like Tom beat me to the X mast flotation. :wink:

Re: What communications radio do you have?

RG58 is 0.195" in diameter and has a loss of 0.061 db/ft. RG8X is 0.245" and loses 0.045db/ft. RG213 is 0.41" and loses 0.027 db/ft. RG213 costs approximately 3x RG58 and RG8X is about twice as expensive. For the length of our boats the power loss is not bad even for the RG58. I ran my coax between ...

Re: So I just bought a Mac X....

When a powerboat user is planing he is describing the case where the boat is ahead of the bow wave. About the time the bow wave passes under the stern of the boat the boat will level out and start going faster without having to increase engine RPM. In fact, you can often throttle back noticeably and...

Re: What communications radio do you have?

What I meant... was my simplistic logic said... a good relatively high-end ($350-$500) VHF fixed radio with GPS and DSC already has every thing needed included some kind of microprocessor for the DSC stuff. If I understand "all" AIS is... takes your GPS and some manually filled-out data and sends i...

Re: So I just bought a Mac X....

One other important (flooded lead acid) battery requirement: it must be in a battery box and it must be fastened so that it cannot move around. Not really placement considerations but you mentioned sleeping next to one in the aft berth. That is not a great place for a battery: too close to the stern...

Re: So I just bought a Mac X....

The answer is, "It depends...". If you have one 12v "marine" battery, it won't make much difference where you put it. I have 4 6v deep cycle batteries. That's a lot of weight an it will affect your trim. Battery placement is a balancing act where you will be playing several competing requirements ag...

Re: So I just bought a Mac X....

I can give you a good idea what the original wiring looked like. The battery was connected to a small fuse panel. I'm pretty sure it was a 4 position panel with glass 5 amp fuses for the entire run of the boat. All of the branch circuits were wired with 18AWG lamp cord. All of the ground wires were ...

Re: What communications radio do you have?

I'm feeling good about my choices. I have the same chart plotter as Nice Aft and had already decided on the same AIS as Highlander :) . Tom, I'm afraid I have to admit I still have my handheld as well, but I did put a much more expensive cell phone on the bottom of the St. Johns river when I leaned ...

Re: What communications radio do you have?

Ok?... You have Standard Horizions radio and Garmin chart plotter. Is there something special about those two or do all radios with AIS capability work with all chart plotters. I've heard a little about NMEA communications, but I assumed that companies try to lock you in to their product line by ma...

Re: What communications radio do you have?

Besides A and B, I didn't know there was different processing options. What do I need to be looking for? And I just assumed that if a radio already has the GPS and DSC (my decade old Standard Horizons hand unit has those) that adding AIS logic was relatively trivial vs having to repeat that GPS, an...

Re: What communications radio do you have?

I have a fixed VHF connected to an antenna on the top of the mast. I also have one mounted on the cockpit rail I can use when the mast is not up (more on that later). I keep an inexpensive handheld in the cockpit. Later this year I will be installing a standalone AIS transceiver that will integrate ...

Re: Trailer questions

I pulled my fairly heavily loaded :macx: with a 2WD XTerra for eight years with no trailer brakes. I could tell it was back there when I hit the brakes but I never felt like it was out of control. I've also never taken it out of Florida (read: mostly flat). When one of my spindles broke I replaced b...
