I miss my 150 Evinrude. That Baby would Haul the Mail! 32 Gallon tank sounds good to me Wally!

Wallace,
I guess I am rusty...right idea, I think, error in execution
I calculated (as did all of us), the area of R2 should be 110 (not 120)X34X0.5=1,870cm^2
Making this correction and using my method (of sum of areas of 2 rectangles and the triangle) and I come up with V=193,860cm^3=193.86L=51.18G

However,
Lee's method of calculating total volume of cube and subtracting volume of the missing half cube seems simpler and sound.  Not sure what's going on here but when I calculate it this way I get a total volume:

259,200cm^3 (total V of cube) - 100,980cm^3 (total volume of half cube) =
V=158,220cm^3=158.22L=41.77G

Not sure what's going on here, I tried it severel different ways and keep coming up with the same 2 answers, I must be missing something here,
It is getting late, and I'm tired from 3 long days of doing science/conference stuff.  Guess someone better check my work.

Just make sure you don't neglect the 10cm spot on top, and use 1/2 X base X height X length for half cube volume.

Given the demensions it seems reasonable to expect it to hold 45-50 gals, so your initial estimate of 175L is prob good.  Fill er up, and find out.  I always had a back up emergency engine(kicker), seperate fuel supply(external tank/jug(s)), and seperate battery (charged but not wired to anything) when venturing offshore.

Yes, It is actually called a fish-n-ski. It has a ski bar that replaces the back seat. I bought it new in 1988 and have many fond memories of it. I sold it this past fall, I was having engine troubles and I'd say 25 years was a good run! It would cruise nicely at 55mph. When I needed fuel, I would drop the wife and kids off at the dock and open her up with only me. With little fuel and little weight, I could attain a speed of 68mph. This picture was taken last September. I took good care of her. 18' Arrow Glass Prototype.

tl 666
not sure myself,ill see what different answers we get
its 9/10 full at the moment

[MFB]

They're a great motor, have a 115 HP on 18' hull is rated up to 150HP, 130 on 19' is about right. Power is a good thing when your going over a west coast bar or having to punch through pressure waves.

Wallace, if you're still not sure, go with the lowest and you won't get in trouble .
Trim tabs will keep that boat steady and balanced, I also believe it saves on fuel if you set them just right.

[wallacewt]

nah its not that sal,my body wont take it.
no jarring for me
i leave earlier,take my time

[Irish Jigger]

Your estimate is very good Wallace.
I calculate the displacement of your tank to be 187.92L.
The volume would be slightly less depending on material thickness of tank.

getting rust off plastic,
I tried this, GUMPTION,after I removed plastic holders.
its terrific,bit coarser than toothpaste,instant
before and after pics

[wallacewt]

starboard side is the same as this,1 in the middle over the engine
clean up,paint,5 metal rod holders
a good day.
cheers
