440 - 4207 Different draft

[1202sam]

Hello. does anybody know why the 440 draws 6" more water than the 4207. They look the same to me.
The 4207 specs say 3.5' and the 440 is 4'.
Thanks Sam

4207 with gas, 440 with diesel? Larger diameter props on the diesel?
Just a guess.

Just comparing some specs...

They both have a beam of 15', but

The 440 has a 15 degree deadrise, vs the 4207 at 12 degrees

The 440 displaces 32,000 lbs, vs the 4207 at 23,600

The 440 shows up at 47'8" overall length, vs the 4207 at 42'

4207 was over 48 feet overall

QR_BBPOST 4207 was over 48 feet overall

I wonder if that difference is the "bow pulpit and swim platform" thing? I got those specs out of the Powerboat Guide

Be careful what the specs say I’m not sure how they measure but our 41CMY measurement from waterline to bottom of prop is 16 inches more than all the spec. say

Curious. What is your actual draft? The PowerBoat guide lists that boat at 31 inches, which seems a little light, but adding another 16 inches inches to that would seem really excessive for that kind of displacement. Do you have prop pockets?

[Steve2020]

Measured yesterday while on the hard it is 47inches from water line to bottom of propeller I would guess the 31” would be to the front of rear strut

[Steve2020]

Opps! No it does not have prop pockets

The best way is to measure your own boat like Steve did, even the same type and size hull will have different measurements when the internal mechanicals are different, for example, diesels, straight drive inboards, "v" drive inboards and pods. The down angle changes can alter measurements.
