I attached the 46” guides to my 2023 Karavan trailer (2023 18' Sea-Doo Switch.) They were easy to install (on top of the frame) and function well. I used a ratchet wrench on the nuts until they were snug and then used the supplied little wrench for final tightening (didn’t want to over tighten.)
I let the PVC pipes roll on the guides when launching and retrieving the boat. With only one person on the dock, the far (water side) pole is sometimes hidden and the boat front can get snagged on that pole. In order to see the pole more easily, I used a 5’ section of white central-vac PVC pipe in it. Fits great and easy to put in and take out.
As for the lights, it is against the law to travel with flashing red lights in Ontario (Highway Act (14) Subject to subsections (14.1), (15) and (17.1), no person shall use a lamp, other than turning signal lamps or the vehicular hazard warning signal lamps commonly known as four way flashers, that produces intermittent flashes of red light.). I removed the red LED’s. I soldered in yellow LED’s and, as the plastic lens is slightly orange, they flash orange. The constant flashing at night is really annoying so I installed an on/off waterproof switch on each light.
The guides help when there is a wind or large waves coming on-shore.
