    adding a pad? good or bad?

    Soooo id like to hear some feedback from guys who have added a pad or lifting strakes, or both to a vee hull. was it a terrible idea? did it work out as planned? would it be better to add the strakes over the pad or the pad over the strakes? any advice?

    My boat only has one set of full length strakes (out of the 3 sets total) and a flattened/ rounded vee the last 5 ish feet of the hull. im wondering if its even worth going down the road of adding a pad or running the other strakes full length to help it fly more, or just accept it as she is.

    Boat is a '92 seaswirl spyder 188

    I considered this as well and what I discovered is its a LOT of work, and a lot of testing and likely a few reworks to get things working at high levels. Doable? Absolutely. Worth it? For me no it wasnt. Bought a hyrdrostream, then another... lol

    im thinking it might not be worth the time and money to go down that road either, the boats gonna need a new floor and stringers soon so thinking about going all out when i do. maybe not so much the pad but i think running the rest of the strakes full length would be worth it????

    Not alot of lift at the centre of the hull, the centre most strakes terminate about half way down the hull so most of the time i believe it just kinda runs flat on the rounded vee when i get it up there.

    The Tunnelboat Design program from Aeromarine Research has a 19' vee hull with a pad already all input... be a lot quicker & cheaper to make changes in the sim; if you're into that kind of stuff.

    Strakes and pads lift the hull -but, only if there is enough hydraulic pressure to lift the weight. You don't mention the speeds, horsepower, or weight so we're all guessing. The vertical surfaces actually increase the wetted surface of the hull if there is insufficient speed to take advantage of the pressure. I've owned 20+ boats through the years and most of those had pads. Very few of those actually needed or benefited from having those pads. My experience with these different Pad-V's is that it would take 60+ mph for any of those to start climbing up on the pad. Only one of my boats could actually support it's full weight on it's pad like a ski. My Allison is still very wet at 60 mph.

    Adding a pad to a boat that will run 55 mph without a pad won't suddenly go 65, 70, or 75 mph with one. Gordon

    currently running 65mph with a G1 Evinrude 225HO with 14" setback and best results with the propshaft around 3" bellow the "pad" and weight in at just shy of 3500lbs boat motor and trailer.

    looks like a cost effective way to see if there is any benefit to adding a pad without actually doing it. I like!

    A pad for 3,000 lbs of boat, fuel, and passengers is way above my pay grade...

    in other words, probably not worth the hassle?

    Just quickly changing the power, weight, setback & height, lower unit, etc on the "demo" boat to resemble yours... 71.0 mph without the pad, 71.9 with. Obviously this doesn't match your exact boat, but the difference with or without a 12" wide pad looks small.

    yeah there are other factors to include but i imagine it would still compute to a difference of not really worth it in the end. a simple repower to a 300 would likely get me 70-75 and thats something that can be done with ease.

    It has good overall manners at WOT, just wish it would “fly” a little better. But every hull has its limitations I guess.
