My 2002 RL80C bit the dust so time to make an upgrade to a new electronics package. Went with the Garmin 1242xsv and the solid sate radar dome. I have reached out to sea scan on a radar mount who has been extremely helpful and has a great radar mount system and willing to match my current hole pattern. My question is does anyone know what angle mount is needed for the arch they go fro 0 to 6 degrees? The arch of the 380 is already angled down. He does sell the mount with adjustment plates that can go from 2 degrees to 6 but figured I would try to find the answer before I guessed as I am not sure what degree the boat rides on when on plane. I have read on one post that a 340 sea ray suggested a 0 degree mount. Any help would be appreciated, I also spoke to Garmin and the Raymarine Auto Pilot will work with the new garmin system using a conversion kit which is a big plus....Thanks

I installed a 4 degree wedge on my radar when I added the Seaview dual mount to accomodate both, my radar & KVH satellite dome.

How about using an angle gauge to measure the difference between your boat on and off plane.
Thanks I ended up talking with Steve from Seascan who is going to make the mount to match current holes, Going with a forward tilt 6 inch base with a 0 degree angle as the radar arch already has a 4 degree angle. Very helpful company with great customer service and very reasonably priced.....Hard to find these days!
We went through this when changing from the Raymarine to the Garmin xHD2 system. The process is:
1. Measure the boat's angle at rest (this is the hull angle to gravity. An electronic level on the cockpit floor will do.
2. Measure the boat's angle at cruise from the same location taken in 1 above.
3. The difference between these is the change in hull attitude at cruise. As the shim measurement will be done at boat's rest position (not moving) a compensation in angle is needed for hull attitude during cruise. Radar's principal use is when the boat is moving.
4. With the electronic level, measure the mount area on the arch. Take that value and calculate the angle to get to level then compensate with the factor found in 3 above.
You then have the angle of the mount. This will ensure the radar's sweep centerline will be horizon at the boat's running attitude.
