How much does weight matter? We all could lose a little weight,... I mean on our boats of course. on a 9000 lbs boat what does 100 lbs do? 500 lbs? 1000 lbs?
Thanks

I read somewhere Formula said every 250lbs was worth 1 mph on their Fastec hulls.

Depends on the boat.

A little lightweight boat could be 2-3mph for 200lbs. and a significant difference in handling too.

Surely, 200lbs isn't gonna really effect a 9000lb boat.

Found this.

Looks like 2000 lbs off a 9300 pounder boat with 1000 hp would be 10 mph increase.

by your formula eq that would be 8 mph so they are close.

I just need to find 2000 lbs to throw off my boat.

Like said it depend on the boat. My Biese drag boat is a total different boat with just one of my kids riding along.

Toss the 500 and 1000 lb fat chic off your boat, you'll see a significant speed increase and probably save a ton on fuel and food bills at the same time!

Aerodynamic drag and hydrodynamic matters too. We can get another 1-2 MPH out of a 37AT just by playing with or removing the windscreen.

Swapping from 280 tabs to 380 tabs, as well as adding normal load tools, spare parts, anchors, lines, fenders, spare fluids, two extra batteries, and a fair sized stereo...
...is taking 3-5 mph off of my top end pending water conditions. I don't care though. I'd rather be prepared than chasing every last decimal point on the GPS speedo.

Remember:
Water: 8 lbs. per gallon
Fuel: 6 lbs. per galon

I also noticed my jeep gets better mileage towing a 24 pantera than my 25 crownline. And they are essentially same weight. So wind resistance against the part of the boat above the water plays a significant role as well. So if you have fat chicks and they like to stand up and show off their huge a$$es you have a double speed penalty...something to be said for spinners...

I know it makes a huge difference in my top gun. Just getting under a half tank it's like an entirely different boat than full.

If I didnt take 800 pds of beer I could hit light speed.
