Swim Platform

[msbhammer]

Hey Guys,
Really stupid question here, but I gotta ask. I mounted your normal type swim platform on the back of my V. Its flush with the waterline.
When I take the boat out now, the boat seems to ride differnt and the bow tilts to the left all the time. Would the swim platform be causing the boat to tilt to the left all the time now, due to how the water rushes around the sides and back of the platform ?????
I did have some dive gear in the boat, but it isnt that much extra weight. DO alot of guys go with trim tabs for this problem ? Ahh, another cost !!
