Water line and angle on 290 AJ help please

[Red Wolf]

I just picked up a 2001 290 sea ray AJ

In the process of mounting a radar arch from Atlantic Towers.

My boat is on a trailer this minute and we are trying to level the top of the arch bow to stern. The water line is it visible to go off of.

My gut feeling is to use the kitchen table top angle for my nominal dock side float angle.

I would only assume almost if not all boats would float with things like tables example a kitchen table as level as possible dock side by design.

Any knowledge on the oils be great I would hate to mount the arch point up or down when the boat is in the water.

We will be mounting it to the gunnel top not the vertical cockpit upright under the side glass

You can see I have a level on top of the arch. I would think if i set the kitchen cook are table level to the world. The correct angle on top of the arch would be level to the world / tipped down a few degrees for the radar.

This is just tied in a close proximity before final angle is determined and mounted.

FYI the boat was stored out if the water on a sling lift. The boot strips are in the process of getting removed and we will be cleaning and bottom painting

Thanks for all the help
