Define 'planing out'

[carlisle]

Over on the repair forum, some suggest that my 12 foot v-hull aluminum boat should plane out nicely with my little, recently overhauled '65 6 HP Evinrude, even at half to 3/4 throttle. Well, I'm not really sure how to determine this. Is it when the turbulence behind the transom smooths out into a uniform, symmetric flow? Is it when the bow shifts downwards? Maybe my expectations are a little high, but it never really seems to 'perch' itself up on the water so that the bow wave moves back along the hull and water isn't spraying outwards, almost all the way to the bow.<br /><br />CHRIS

Re: Define 'planing out'

When a boat planes it goes from pushing the water to the side (displacement speed) to riding on the top of the water. In a small boat such as yours you should notice a change in the sound of the motor as the rpm goes up. The transition is known as climbing the step. The bow should drop down also.<br /><br />Your 6 hp may be able to plane your boat if you are not a heavyweight and have the load properly balanced. You may need to put some weight up forward. You may not be able to plane as, at least in my opinion, that is asking a lot from 6 hp. I know a 9.9 will get a 13'r on plane as I have one.

Re: Define 'planing out'

I think the boat should plane but it is never going to run very fast. In a boat this size, everything makes a difference, where you sit , your weight, other loads, motor trim angle, etc.<br /><br />Where is the motor trimmed? Do you run a Hydrofoil? Need a bit more info.
