Anyone know of a Velocity that is sitting out of the water anywhere around me? I'm not looking to buy anything right now, just more looking to learn. The engineer in me is never going to just "use" the boat to go boating. That much I know of myself.

Besides everything previously mentioned the X dimension is very important. If the prop is running too deep, trim response will be poor and the boat will run wet, (too big a footprint).
At speed wake should be breaking at or behind the helm. Maybe a Bravo "shortie" will help. |

I also like the ride of a 38 TG and Formula with steps. The stepped bigger (42- 47' Fountains) are fine. I'm also wondering if steps are even necessary in a boat that small? They obviously help a great deal on the bigger boats you mention, but do they do anything on a fast, small boat that only runs on the last three feet anyway? |

The x-dim or more importantly the distance of the prop shaft from the bottom of the boat was another question I'm looking at: If you're going to run a modern "normal" 4 blade prop (Like a bravo1) how far would you put it below the hull bottom? I assume the kind of water you run in plays a factor in this. You obviously don't want the prop coming out of the water on every wave. How far below does velocity put their props? Anyone know? |
The X on my outlaw is a makes-me-sick-to-my-stomach 7"
I'm currently working to improve that somewhat. |

Here is a bad pic ( only one I have) of the bottom of my 26 Corsa. If you click on the pic and enlarge it you can see how wide the strakes are. The bottom strakes end a few feet before the transom. I set my X dimension at 18 1/4". That puts my drive shaft around 3 1/2" below the keel. This hull runs extremely well in the rough.

[QUOTE=bcarpman;2631597]What does that mean "wake should be breaking at or behind the helm"?
When you are on plane and driving, look over the side and see where the wake is coming off the hull. If it is forward of the helm, you may be running the hull too wet. If you can't trim the outdrive enough to pull the wake aft, chances are the prop is too low or you are getting too much stern lift. |

3.5 inches? Wow, I think I'm about 12 inches. Doesn't that put part of the prop out of the water? Is it a surfacing prop? |
I would add that the boat needs to be "still" with 2-3 degrees to bow lift...ideal balance. Nail this balance with the perfect X and an average production hull with a straighten/flat bottom can make amazing speed with superior hull efficiency. Reggie spends more $ on dialing in the right set up on Fountain's production boats than most.
