Default Onslow Bay 33 step hull twin 350 Verados

Here are some pics of the first 33 step with the twin Mercury Verado 350's. We will probably run this boat next week and I will post numbers. Made some setup changes from first step hull and of course added some horse power. It's home will be in Jacksonville, FL with Don Frattle and will be called "Fratt House"

You sandbagging?

33 Invincible with F300's hits 62, I'd bet you get more than 64 light.

Maybe, but keep in mind that the Invincible has less deadrise and a notched bracket. It has about 2 feet less length along the centerline in the water than our 33. Since we extend the running surface all the way to the motors, our bottom is essentially longer as far as the ocean is concerned. That gives us more bottom to span waves, and more lift in the transom. On the downside, we have more bottom in the water which requires more power to push it the same speed as a boat with the notched bracket. Personally, I will take the trade off. For the 2 mph that we may lose WOT, I would rather have the ride in the ocean with the extra running surface length.

No, I'm going twin 350's. I think it will be our most popular boat and I should therefore have one in this configuration for demos.

We sea trialed "Fratt House" today. It is a 33 Tournament Edition with the new Mercury Verado 350's (twins). We had 4 people on board, and 100 gallons of fuel. We were into a current that was between 1 and 2 mph. The following numbers are with the current taken out.

Top speed (GPS) was between 64 and 65 mph. Fuel economy was 1.8 mpg at 40 mph and 1.7 at 45 mph. Very happy with these numbers. Mercury Marine has a winner with this engine.

Awesome numbers! What props? If you haven't tried a set of Eco props yet, you should.
