here is how the new ruling is worded, this is from the NAMBA website
The following proposals relate to Section 20 which deals with Sport
Hydroplane racing rules:
Proposal #8: Replace existing Section 27.B.4 with (additions are italicized):
The boat must be attractively painted in the spirit of Limited or Unlimited inboard
hydroplane racing. Each boat must have a sponsor’s name or logo affixed to the hull.
The sponsor may be of the builder’s choice: a hobby shop, gas station, local business,
fictitious sponsor, etc. The boat must have the driver’s NAMBA number on it
preceded by the letter “U, UL, GP,J” Or any other limited or unlimited inboard
hydroplane racing designator past or present used by major full sized sanctioning body
such as but not limited to the APBA. The number can be on the hull or tail. In cases where
the boater uses the real Unlimited Hydroplane’s “U” number, the driver’s NAMBA
number must appear somewhere on the visible portion of the boat in numbers at least
1/4” in height.
Proposal #9: Replace existing Section 27.B.11 with:
No boat will have an after plane greater than 60% of the total length of the hull.
Length “C” will be measured from the transom to the point where the sponson is
attached to the hull (Figure 1).
Note: This change, if passed, would eliminate Figure 2 in this section as well as the
second column in Table 1 which relates to belly pan depth
But, to tell you the truth the bottom mod makes for a better handling boat, just my opinion
