Is there a need to have both on a boat?

A buddy of mine has that set up on his boat don't know why but he cant trim the boat for sh't, it pulls to the side.

It seems to me that it could be a real problem trying to trim a boat with tabs and a diverter. If not just right, wouldn't they work against each other?

Thats exactly what happens .
Trim tabs can also be installed horizontally to keep a hull from chine walking .

I have had both on two different hulls...Spectra 20 and a 19' aluminum, they work bitchen with eachother. but from what I understand they aren't needed on lighter smaller hulls, never tried it though..

On a lot of boats they are an absolutle neccesity, diverter or not , some they seem to have no effect we use them for "tuning". In the "nuetral position they make the boat think its longer and adjusted or actuated down they create a kind of "hook" (lifting) at the bottom of the stern to help force the bow down , tunnels use them to close down the air drafting thru and help with lift The Sanger wouldn't be drivable at all without them ;D

after putting a new engine in my little day cruiser this past winter along with moving my pump back I discovered that I absolutely need to put the trim tabs back on. It is completely undrivable and just wants to keep putting the nose in the air. My old v-drive rode better than this does.

Well, then, I guess I'll keep the ones that came with my new project and put them back on. Thanks
