Default Mounting a radome

Hello all,
I am having a T-Top made for my boat on which I will install a
Raymarine radome. Is there any advantage to mounting it on "power mount"
(Seaview) as opposed to mounting it directly on the top, other than
gaining a few inches in height? The top will be canvas with a mounting
plate installed.

Thanks,

bob baldwin

A few inches in height won't make a world of difference, assuming your bow
doesn't rise too high while underway and hide the view straight ahead. I'm
not familiar with the current RayNav domes, but in the past, some had attach
fasteners (Just for the dome cover, now) which pointed up from under the
lower half of the dome. If that's the case, it is helpful to have enough
clearance to get a screwdriver or wrench under the dome.

How much clearance is there? Enough to let you install/remove the canvas
without the radome interfering? The mounts generally let you get two
things: clearance and down tilt. Speak with your boat maker about how much
tilt is common on your model vessel. You don't want to have the radome's
plane of coverage being so low as to not clear the bow (not very likely but
something to consider). Also check what the total height would end up
being. No sense making the radome higher if it ends up being too low to
clear bridges. Again, not terribly likely but something to consider.

The seaview mounts also have options on mounting the light behind/above the
radome. A nice way to keep the arch from getting overly crowded while
keeping that nav light visible.

Chief Lynn,
Thanks for the info - yes, mine has the holes that are hard to get to,
but it came with little screwdriver made to fit up under the dome's
edge. A little extra clearance would be nice, but I will probably just
mount it level on the top (while on plane) and use that screwdriver.

Thanks again,
bob baldwin

Bill,
The canvas on my new roof is "permanent", at least, till it's time to
replace it. The canvas is laced all the way around the aluminum
framework. I have a Stingray Hydrofoil attached to the outboard that
helps keep the bow down, and the top is 80" above the floor. The boat is
a small 19' center console. I think I'll make some kind of wedge to tilt
the rear of the dome up slightly so that it will be level while at my
normal cruise speed. Those holes under the dome almost require the
special screwdriver that came with the radar - it's a very close fit. I
had seen those power mounts advertised, and didn't know what they really
provided. The nav light idea is good too.
Thanks to you and everyone that responded with ideas.

Consider using longer bolts and some stainless sleeves. I don't know how
your setup actually installs but that's probably the most reasonable way to
get the tilt.

Yeah, those are pretty clever aren't they. My arch actually has a stern
light that's to the starboard of the radome, on a ratchet mount. The pole
goes up, bends to port over the middle of the radome and then up about 6"
for the light. Dunno who makes it. But it allows the radome to be centered
along with the light. The radome's mounted on an area of the arch that's
molded with some tilt already in the fiberglas. The radome's then mounted
on sleeves about 2" off the gelcoat. Seems to work nicely both on plane and
off.

Bill,
Those sleeves sound like a good idea. I drilled out the mounting plates
this weekend and mounted the radome. I'll need to get longer bolts
anyway because the mounting plates are a full 1/4" thick. I can put
short sleeves in front, and slightly longer ones in back for tilt. Don't
think it will need much tilt with the stingray tail on the outboard, but
extra clearance for that little screwdriver is always welcome. It's
going to hurt drilling through the new canvas top to feed the radar
cable up to the dome, but it has to be done. The cable will run inside
the t-top tubing all the way up and will be hidden for the most part.

Regards,

bob baldwin
