Scoop, anytime the majority of the weight of a boat is in the back, in your case, the far-back, bow rise will be noticeable more so than boats with the under-seat tank like our Caracal. The forward weight diminishes bow rise for us, and our hole shot is very fast when the tank is 1/2 full to full.
The good news is, your boat will be faster, once it’s out of the hole, than comparable boats with more weight forward, six of one, a half dozen of another…
To answer your question, adding weight forward will decrease the time for the boat to plane from a stand-still.
