For a 5m boat should be very quick.
I got into boating since I was given a 4.2m inflatable with 15hp outboard. I soon realised it was too small for what I want to do, which is heading out to coastal reefs, such as long reef. I then bought a new quintrex sea spirit 510 for that purpose and to learn on. It seemed daunting at first driving it onto the trailer, but just a few goes it becomes so easy. It didn't stop there though, soon after the Qunnie I wanted to so further out to sea to fish species like tuna or marlin(which I'm yet to catch), which got me into a 6m glass boat. From my experience the 5m aluminium boat is much easier to handle and forgiving, so a better learning boat.
