Question Aft/Forward Mount or No mount Radar??????

Looking for opinions. The more I search the more confused I get. The boat is a hydrasports 3000vx. Radar is used for a few days in april/may for fog and then nights in summer.

All good thoughts appreciated.

Not at all sure what you're asking. Do you mean should you install a RADAR? Or what sort of RADAR to install? Or where on the boat to install it? Or what sort of hardware to use to install it?

The number of days to be used, during particular calendar months, and what types of restricted visibility, are not pertinent to selecting a radar mount. Knowing which antenna you have in mind and where you will mount it would be important to know.

Furuno 24 dome. I guess my question is, how much feedback to you get from rod holders or a search light to need a mount? Does an aft or forward facing mount make a difference or is it just for personal taste.

By the way, I am on the Great Lakes.

The non-technical answer is that most typical obstructions, such as fishing rods and tower legs are insignificant. However, if you can eliminate items in the path of the radar beam with a mount, why not do so. As far as the choice of aft or forward leaning mounts, each is designed to fit a particular mounting situation. Where either orientation will work, it becomes a matter of esthetics and personal preference.

well worded pez. thanks. 6" 4 degree tiled aft sound good then.

I have a slight tilt forward, allowing the dome to be level at the running angle of the boat..it's tilts forward while at idle speed, which can't be all that bad for close targets. Some accessories say not to put them in the beam path (gps, sat antennas etc..)

Once you have it, you'll want to use it all the time.

You really don't want any of that stuff within the RADAR's transmission beam, if you can avoid it. Most very small objects like VHF antennas will not be debilitating obstructions; but they aren't going to help, either (and in the particular case of antennas, MAY pick up interference from the RADAR). Best to not ask for trouble.


Does an aft or forward facing mount make a difference or is it just for personal taste.
It's more about mechanical security. An aft-swept mount atop an aft-swept RADAR arch, for example, creates that much longer of a lever arm for the RADAR unit's weight to bear on the arch's mounting points. Most of the time, it won't be a problem; but again, why ask for trouble?

Hold on!

That's not what Pez meant by "aft or forward leaning". Regardless of the mount style or its location, you want the finished installation to tilt the unit itself downward (at the front) by perhaps four degrees or so. The precise angle isn't critical (you basically want to split the difference between the boat's at-rest and on-plane running angles); but it should NOT be the other way around!

It's a hard top. No arch.

And the arch example was exactly that: An example. The principles remain the same, regardless.

24" vs. an open array?

So are you saying you would never use an aft or forward mount because of structual issues?

The way the mount itself leans is personal preference. For my new Simrad 4G, I bought a 100% welded stainless BattleWagon Aft leaning mount with a 4 degree angle. The mount itself leans aft so it matches the lines on my Fountain 38LX better than straight or forward leaning. However, the mounting plate on top of the mount has a 4 degree slope down. Structural integrity IMO is a non issue. Don't under estimate the strength of a good weld. I have had mounts on all of my boat over the past 12 years. Even with the older larger and "heavier" radar technology, I have never had any issues with radars or mounts. Pick what fits your needs and preference and be done with it.

I have included a couple of pics of my install to give you an idea. I am not quite finished with the install so you will have to forgive my mess but you can get the idea.

Good luck.

Again, your question is not clear. Are you asking which type of RADAR unit you should buy? I thought you had earlier said that you had a "Furuno 24 dome"?

No, that is NOT what I am saying.

I merely suggested keeping the overall structural assembly in mind when choosing a RADAR mount. Given a well-designed and well-installed hardtop with multiple widely-spaced (and more-or-less symmetrical relative to the center of gravity) mounting points, this is very probably a non-issue from a practical point of view. But it's just one more part of the overall picture; and it can't hurt to consider it.
