    I have a 2007 SeaRay sundancer 2007. Great boat, but it rides so bow high at cruise even with the trim tabs fully down. Is it just the way it is or can something be down?

    You don’t mention what boat you have, nor does your profile page list it. 320, 340, 420, 240, etc. also, do you have v-drive, or I/O (stern drive). When the boat is out of the water, do the trim tabs actually work and move all the way down?

    2007 31 ft SeaRay Sundance with V-drives. The tabs do work and go all the way down, but does not lower the bow enough at cruise.

    When you say "cruise", what speed are you talking about? To me, this would mean, at a bare minimum, up on plane - say 20-ish mph. Do you happen to have a bunch of people or gear sitting all the way aft?

    The boat will plane at 16-18 knots. But even at 20-25 knots the bow will not lower any more.
    It could be just the way the boat is, or maybe needs larger tabs or tabs that lower more ??
    I recently purchased this model and maybe have to get used to it, but I can`t help but think that there is a solution.

    1E943CE3-5FF0-4A89-B965-A0641D7D6F87.jpg My 2012 310 feels like the bow cruises high, like you mention, however, realizing cruising speed is 15+ mph and playing with trim tabs I finally got her right. Bow starts to drop and she's on plane past 20mph. Keep try and get the rooms over3.2-3.5k than ease up and trim.

    This may sound silly. Are you working the tab controls correctly. At first, the intuition I had was just opposite of how the tab controls actually work. You may try doing just the opposite of what you have been and see if it changes the ride.

    With v-drives, you obviously don't have the added benefit of drives to further help your trim. How much weight/people and where are they?

    Is this your first cruiser? Meaning, something with a longer bow sticking out in front of you? This is going to be a tough one to figure out via a forum as "too high" is subjective. If you could get a friend to drive next to you and take a few pictures, that would help.

    If the bottom is dirty, that could affect things, too. Increasing tab size (especially the span) is NEVER a bad idea, though... if you have the room, of course.

    The weight doesn't seem to effect it. Tab size seems the most logical answer.

    use a couple hundred feet of chain for the anchor rode to replace the rope....chain weighs about 1 lb. per foot......that will help bring the bow down....

    What about the question about "first cruiser"?

    With my boat, I press “up buttons” and this makes the tabs go down. Which is opposite of how I would think they would work. Also, left button changes the right side tab, again, opposite of what you would think. However, I don’t think this is your issue, since you know the tabs are moving down.

    I know in my 370 that if im light on water it will do the same thing. One most cases I rin 1/2-full tank of water. my water tank is under the v berth... so that really effects how she rides ecp if im full fuel. my suggestion would be to fill the water if the tank is under the v birth, try 8-10 seconds of trim tab before you make the jump from trolling speed to hard throttle.
