We interrupt the political programming to bring you a boat question.

My 14' Lund aluminum yacht has been exhibiting some odd behavior at the
transom, and the last foot of the sides. Lots of spray. I've seen transom
spray when the motor's been dragging a large clump of weeds, and spray from
the sides when the boat's obviously (but rarely) overloaded. Now, I'm seeing
a combination of both. Absolutely NOTHING about the boat has been changed,
at least not by me. No accessories added or moved, and the motor hasn't
banged against any obstructions, and its angle has not been adjusted in
years. There is no bilge, so I'm positive it's not a matter of collected
water.

The boat's bottom has two strakes, about 8" out from the keel. The keel &
strakes are in perfect condition - no dents, all rivets are tight and
there's no debris snagged between the hull and the metal strips. There's an
aluminum spray strip along each side, also in perfect condition. The problem
seems the same whether the gas tank is full or near empty, which I mention
in case anyone's still wondering about weight issues.

If the hull had somehow become misshapen, perhaps by the trailer bunks, it
seems it would be obvious, but perhaps not. How small a change to hull shape
cause this type of thing?
