dont forget to order the base plate for your radar ! THIS IS SOLD SEPARATELY !!!!Perfect size. High enough for my radar too work properly. Easy installation. The reason for 4 stars... I understand the base not coming with mounting bolts, but it should come with an adapter plate. Very happy with my purchase.this radar mount fit my needs perfectly for my 2003 Sea Ray Sundancer 320. My boat had never had radar on it before and installing was not to difficult, although drilling 3/8" holes is not fun. use at the very least 4 drill bits if drilling gel coat at that size of hole gel coat is easy to chip and crack. The mount looks great and the way everything else (mounting plate, light bar, nav lights) attaches are easy to install. none of the seaview products come with directions but if you go to the website they have PDFs of them.great product and install was cake. i installed this with the spreader kit (wing) for my gps and xm works great, and the baseplate for the garmin radome was spot on.Customer service is awesome as well.
