I have a little 27 Excalibur
that is 24 deg bottom and only 6' wide at the transom
to top it off has wide lifting strakes and lower strake is only 3"
from bottom of vee
this hull rides very high out of water at 70+
the tabs were soo touchy that I went to 24v pump motors on 12 volts to slow tabs down
as would toss the boat from side to side if bumped too much
and raised the motors to allow hull to ride deeper so would not be soo drastic
with them mounted following the bottom
have the boat riding real nice and can cruise 70-80 in 2'ers
want to try tabs horrizonal
and lower the motors as I have more slip in rough water 3'ers than I like
luckily im runnin trip outboards so moving motors is easy,,,

just spoke to Mr Simmons of the APBA hall of champions fame 
and he say go for it! in a nutshell it was a plus, didnt have much affect on turning but rough water ability benefited greatly. I was told the boat will land flatter and fly straighter. Angle mounting the tabs tend to give the boat side side to side squirrely-ness that horizontal mounting corrects.You need this ROB . . . although i dont know if its you or that boat that is squirrely . . . . and maybe you wont have to call your mommy when it gets rough out

Mine is not a 24x7 nut 27x8 with 25deg V and it also has tabs horizontal.
:less chance of chine walking,less drag, and if gives me ability to bury the nose
evenly and stay on plane at half the speed i can without them.

Some info I have gathered in my quest for an answer:
The following is from Tegque on tech, Power boat mag.
I have a 1999 21' Baja Hammer. It is equipped with a 7.4-liter MerCruiser engine, and has a top speed in the 65 to 70 mph range. It is great for the lake we live on, but occasionally my son and I take it to a much larger lake for a poker run.
While the top speed is OK to run with most of the boats, the handling gets a little out of shape especially when one of the much larger boats goes past and we cross its wake. My question is would trim tabs help or do I just buy a bigger boat?

Answer: Adding trim tabs would help to settle the boat down in the cross wakes. Using them will result in a reduction of your top speed, though. When they are up, the boat will be the same as it is now. They can be lowered just enough to improve control without scrubbing off too much speed. I would install them toward the keel, a little in from the traditional mounting location out by the chine. This will allow them to still be effective when the boat is riding high up on the keel and the chines are pretty much out of the water. I also would consider mounting the tabs horizontally as opposed to parallel to the bottom surface. This will allow the outside tips to touch water before the whole plane does. Sometimes, when the planes are mounted parallel to the bottom, the angle of the plate accentuates the chine-walking motion as the boat launches off each plane alternately.
