    Default Spoon the bottom????

    what can you expect to get going from a flat keel "in a daytona" to a spooned bottom? is it worth doing it? i dont have a ton of HP but i getting tired of trying to load the pump to a point where its not starving the pump. any of the pros on the boards your advice would be appreciated.

    I definately am not an expert on the Daytona, but just going to a radiused keel from the flat keel is worth more than a nickel at 90. Going to the drop keel is going to have more to do with your hull and engine combination. I'm going to go out on a limb and say at 800 HP it will be worth at least 10 MPH above 100.

    Most definately is worth the money. There is a '78 Eliminator locally that has a 555" BBC of decent build and a Bennett bottom that runs over 110 in lake trim.

    And it will be safer coming down from speed.

    Thumbs down

    I have keeled 2 daytonas and both picked up 5 to 10 mph with 600/750hp,also keeled v bottoms and gullwings and all responed to the keels. Would spend time and money for a keel.

    the 1st boat i keeled was my eliminator sprint with a delta pad bottom,had 550hp 454. I still picked up 10 mph even though it lost 1000 rpm. The boat ended up running 93 mph at 5000ft with 640hp. recommend a keel on almost any boat you want to run hard.

    whats the thought of doing like a nasa duct instead of the spoon, sure that nasa spent millions on research and allegedly this is the most efficient design to feed an "intake". thoughts or experiences?
