Are you asking because you want to buy one? If so, it's your business but do you really need to go 78mph?

What’s a list of bass boats (20-21ft) that can hit 78+ consistently with a 250, also if it’s rated for a 300 can.
My previous fx20 was a 74.5 mph boat. Ranger 520L is a 71mph boat.

Why the need to go in the high 70s? A better question is what bass boat handles rough water the best.

The new Gambler line (Both Models: 20'7" & 21'9") out of S.C. will run in the mid 80s & low 80s with a stock 250 SHO. They are not mass produced so they you don't see them very often, but they're very nice boats with a comfortable ride. https://www.gamblerbassboats.com/

Just visited their website and watched the video----Sorry, I'm not buying it--I was born in Missouri so they would have to "SHO" me (No Pun Intended--LOL). Numbers simply don't add up to their claims. Prop slip calculator says 4%-5%---On a 2100lb hull---Yeah Right!! Most hulls I am familiar with at similar weights can't even turn a 27P prop, when and if they can get on plane, prop slip would be in the 15%-20% range! Matter of fact, they are saying they get a lower slip % than I can running a hull nearly 1000lbs lighter!!! There will be those of you that say they have a better hull design---it is different but it still takes HP, TQ, and RPMs which mean the ability to push all that weight and the numbers simply don't add up! "EVERY" prop become less efficient as weight goes up no matter the hull design 2000 lbs is still 2000 lbs. Allison builds the most efficient hull in the bass boat market, this is so simply because of weight and hull/pad design. Because they are lighter they can turn a much bigger wheel. Because they run on about the last 2 feet of the pad means less friction. Because of these 2 factors alone makes them faster and more efficient. For Gambler to say they can turn a 27P prop on a 2100 lb hull at 5900 rpms @ near 82 mph, when other boats of similar weights would be lucky to turn a 25P prop at the same RPMs is a big mouthful!! Everyone of you knows that when you add a person or 2 to your boat what happens to your hole-shot and top speed??

Basscat Lynx with a 300 can hit 82-83 with a good driver. Myself, best I have done is 81. I also threw my wife out going only 60 mph so don't take much advice from me. When i'm fishing winter time, I will use my speed prop fury 3 blade worked by ronny gilbert. horrible hole shot and rough water is a little sketchy at top end with 3 blade. When I fish my little club tournaments or a media here or there, I will put my bravo 1 fs 4 blade and best I can get is 78 but the mid range and rough water ride is crazy good. doesn't get to walk until after about 78-79. I hear people say all the time "why would you want to go 80". 95% of the time Im going mid 70s. Sometimes, its nice to just let it eat. A slight rush to it. same reason people buy corvettes and all those when clearly the speed limit is tops 75. sometimes you just want to push it.

Gamber's concave pad and reverse chines pack a lot of air under the boat. This helps with lift and reduces friction. Yes they go that fast weather you believe it or not.

I guess I should have been more specific--I am aware they are a fast boat, been around many of them. My issue is believing they will run that fast with a stock 250 and a 27p prop
