I have used the Stingray brand on a couple of boats. I really like the one on my little SIB as it planes at just under 13mph even with a light load. The wake is far smaller, allowing me to plane in areas I probably shouldn't without feeling too guilty. When loaded with people and dive gear to the gills, I can still plane. With that said I wouldn't put a wing on a 5.4meter boat, but instead look to trim tabs on the hull. More versatility, with the ability to level the boat. That is of course assuming the transom has the room, around any elephant trunks, sonar units, etc. If it were me, I would be doing a lot of research to pros and cons of both systems.
