Bow heavy on waterline

Greetings
I am an owner of a 1981 Seaforth 24, built by Precision Boatworks. This is the model with the 8hp Renault Diesel Inboard.
When viewed from the dock my boat appears to be bow heavy on the waterline. Even after I removed every single life jacket, extra line, coffee mug, etc. from the boat, it still sits so.
I am thinking that it has to do with the addition of the inboard diesel in the later productions, instead of the outboard in a motor well. Any body else ran into this problem?
Sorry I do not own a camera. Otherwise I would have taken a picture. I can assure you it looks exactly as you might picture it, with the waterline at the bow sitting about 1" lower than the stern.
Thanks,
Marlin

Where are the water and fuel tanks located and are they full or empty?

The fuel tank is located amidship, next to the engine. Likewise the two batteries I carry are located amidship on the other side of the engine. The fuel tank is stainless, glassed in place. I don not carry water in a tank and the fuel tank is half full.

Put 400 pounds in the cockpit and see if doesn't settle out evenly on the waterline. Three crew in the cockpit will probably right this imbalance.

Are you sure the water line is painted correctly?

How does the actual waterline compare to the attached line drawing (ignoring its currently painted waterline stripe)? It does seem like they should have compensated for the shift in weight when they moved the engine from the back (outboard, probably lighter) toward the front (inboard, probably heavier) in some way such as reshaping the ballast, but perhaps any solutions were a more costly a proposition then they cared to take on?

I haven't tried, but I wonder if you can find Google or Yachtworld images of sister-ships at rest for comparison. If no solution, repainting the waterline might not be a bad idea (else, tilt head when looking? )

Is the boat floating BELOW the waterline forward? Usually the bottom paint comes up to the designed waterline or the stern is high (several additional inches above the designed waterline)...

May boats will float a bit bow low when crew is NOT in the cockpit. Mine is that way a bit too.

There is a Piper? that is not right, the little flat bottom cabin new boats that folks buy here at my marina, when empty, very nose down, with a person or two in the cockpit, it would be level.

I would not worry about it personally.
