Using
the vessel's 3D solid model, in Pro/DESKTOP, I determined the
precise mass properties for a single hull at various immersion
depths. Measurements are given from the waterline to the bottom
edge of the transom, on each hull's centerline, for convenience.
Because SEDATION
4 floats
"level" by design (unlike
Kit-Cat
boats which are quite stern-heavy) NO COMPARISON of
draft-to-displacement is applicable to other vessels based on this hull
model. The narrow bow sections are much less bouyant than
the
wide aft sections. The deep "rocker" keel amidships (at the point of
maximum draft) provides a bouyant pivot point which makes the hulls
very sensitive to fore-aft weight distribution. For
example, filling the bow water tanks with 171 gallons (1425.5
lbs) will cause the transoms to rise by only 2" while the bows
sink almost 4.5" with the vessel in her present static-load condition
of ~18,700 lbs. This is why most heavy components (batteries,
fuel tanks etc.) are located amidships.
