My testing ground for this modular top plate was my 32-foot sport cruiser, which spends most of its time moored in a busy marina with moderate wave action and regular exposure to the elements. The installation was performed during a routine Saturday maintenance session, a perfect opportunity to integrate this component into my existing setup. The unit was mounted atop the existing pedestal, integrating seamlessly with the 24-inch JRC dome it was designed for.

Initial use involved standard operational checks, primarily ensuring the radar could sweep 360 degrees without obstruction and that the dome itself was rigidly secured. Over the subsequent weeks, the boat experienced typical coastal cruising conditions, including light chop, occasional squalls, and prolonged periods of direct sunlight. I specifically monitored the radar’s performance for any anomalies that might suggest movement or vibration from the dome, and thankfully, none were observed. The PYI / Seaview Modular Top Plate for Select 24in Radomes held its ground admirably.

After several months of consistent use, this modular top plate has proven to be exceptionally reliable. The King Starboard material has resisted any visible signs of degradation, such as fading, chalking, or becoming brittle, despite being directly exposed to intense summer sun and numerous saltwater washdowns. The mounting hardware, which I supplemented with marine-grade stainless steel bolts and nylock nuts, remains secure with no loosening. Cleaning is as simple as a quick wipe-down with a damp cloth, and it hasn’t required any specialized maintenance beyond that. Compared to the original, which began showing wear within two years, this Seaview component feels built to last significantly longer.

First Use Experience

The installation process for this modular top plate was straightforward, taking approximately 30 minutes from start to finish. It required basic tools found in any well-equipped marine toolkit. The unit was fitted to the existing radar pedestal, and the 24-inch JRC radome was then secured to the top plate using the provided hardware.

Performance in varying conditions was a key focus. During a particularly choppy weekend, I paid close attention to the radar display for any evidence of vibration from the radome. The display remained clear and stable, indicating a secure mount. The unit was also exposed to a moderate amount of rain and spray, and I observed no water ingress or issues with the mounting mechanism.

Ease of use was a significant factor, and thankfully, this top plate required no real learning curve. Once the old plate was removed and the new one was positioned, the process of reattaching the radome was intuitive. The pre-drilled holes aligned perfectly with the standard mounting pattern of my JRC dome.

There were no major surprises or quirks upon first use. The most positive aspect was the immediate sense of increased rigidity and security the radome exhibited compared to its previously worn mount. It simply felt “right” and properly supported.

Extended Use & Reliability

Weeks of continued operation have solidified my positive impression of this modular top plate. It consistently holds the radar dome firmly in place, even during aggressive maneuvers or when encountering larger waves.
