I added some red pinstripe tape to the port rudder arm and port side of the tiller crossbar. Takes the guesswork out of reinstalling your rudders correctly after removing them for transport.

Most states have a 6 foot overhang law measured from the rear support of the trailer (rear hull cradles/rollers/etc.) to the end of rudders/mast/hulls (whichever protrudes the most). Anything beyond that requires a red clearance flag. Some states even require a red clearance light to be attached for night travel. Check your state trailering regs and make sure you're legal.
