I would tend to doubt that the 228R uses a pole for its forward nav lights but I guess anything is possible. Most Hurricanes and other boats in this class have the forward nav lights port and starboard. That being said most marine stores have a variety of add-on nav lights, some of which clamp to the railing others use suction cups and so on (if you are looking for a quick fix). As far as the aft nav light. Most but not all earlier Hurricanes have the stern light attached to and wired through the back rib of the bimini. I have seen a couple of 228R config'ed this way. Clamp-on stern lights are also available if you aren't up for a wire job. BTW, these are USCG approved.
Hope this helps.
