    Can Trim Tabs be dangerous

    When i had my 625 Cruise Craft i asked to fit trim tabs and his answer was it did not need them and they could be dangerous.
    Any thoughts on this.

    Yeah. I installed a Permatrim on my 115 Yammie 2s a few years ago to get better slow speed planing and better control. Never regretted this. This boat has been in all sorts of seas from offshore Sydney to many, many reef trips in its current home in Nth Qld. Never any danger from following seas which is an urban myth spread by others with an agenda.

    What's that got to do with trim tabs & why they're dangerous?

    I had tabs fitted to the victory a few months ago. I cant imagine life without them now.
    They help you nose down into the swell, correct a list effortlessly and deal with a sea coming onto your front quarter . I tend to get them pretty much out of the way in a following sea but I cant see where the danger is except if you make gross adjustments very quickly.
    I'm a definite vote in favour.

    Re: Can Trim Tabs be dangerous

    Hey Tenzing, I have thought about them on my 575 outsider. I have used a set on a 6.8 metre plate boat once and found that they can be very scarey if used in the wrong conditions. We were going in towards Stanage bay boat ramp and I wanted to keep the nose down in the lumpy conditions as well as correcting a list towards the port side. I lowered the port trim only and it nearly flipped us out the starboard side. My advice would be to make small adjustments when using just one side and see what the effect is. When using both together then I think faster trimming would be fine. They worked really well at keeping the nose down when heading into the waves, which stops the boat from rising then crashing into the next wave hollow.

    Yep who ever said it was a fool!


    The cruise craft DOES need tabs . in fact all mono hull boats over 5.5m should have them fitted as standard imho as they make a boat handle the differing conditions of the ocean soooooooo much better! I guess they could be dangerous if totally mishandled but mishandle a boat and it's dangerous, in fact mishandle a glass of water and it's dangerous!

    It would take you about 15 minutes to start working out how to use tabs properly, not real difficult mate!

    There are some really brilliant people on this site and Ian / Finding Time is one of them. Well said Ian. Spot on about boats from 5.5m on benefiting; be they tin, plate, plastic or glass.

    When I first read this thread I thought what a load of BS; on the same basis drinking water, eating food and crossing a road are all dangerous if done wrong.

    How about a bit of common sense pleeease!

    Hey Chris,
    I took mine for a run in the broadwater as soon as they were fitted, and had the same kind of experience.
    Firstly in a balanced boat they are not that necessary in the still water.
    Secondly, reading the instructions really helped. Bennett recommends activating them in 1/2 second bursts. Certainly when using both there is not such a problem but with one side at a time the short bursts are definitely the go as the boat takes a moment to react to the change.
    The other thing is that the control pad with indicator lights is EXTREMELY useful.
    My model has an automatic retractor feature which I have interrupted with a separate toggle switch, otherwise if you are drifting the little motor goes off for 10 secs every time you turn the boat motor off. I normally just activate it when we set out in the am , and when we turn for home.

    I've got them on the 650 sea legend and love them. Did have a moment once , had been running with the portside tab down to combat a rather stiff brease on the starboard bow . After stopping for a while then when we got going again this time in the different direction , motor trimed in and brease on the port bow gave it the berries to put it on the plane , came up on plane quickly but with a nasty lean to starboard as I had not retracted the trim tab , now I have got in the habit of retracting them as I come of the plane. Didn't think it was dangerous just a bit off putting.

    Ditto to all the above.
    Have them on my HH560 - took a bit to learn optimum positions for tabs & motor trim in various conditions - a good fuel flow meter is invaluable.
    Yes that can be dangerous ... in the hands of a reckless idiot or inexperienced tosser ... having them down in a following sea is usually asking for trouble ... like trying to pull a stuck anchor with a rear corner bollard.
    A cautious approach / learning curve is all thats required & you'll enjoy much beeter ride & probably better economy /performance depending on your rig & how you drive it.

    This came from the Dealer i bought the boat from and he had the same boat.
    Just curious as to why he would say this as he would have got extra dollars.

    Re: Can Trim Tabs be dangerous

    Had them on my last 2 boats and they were great for all the reasons already mentioned. Never found them dangerous. Don't have them on my latest boat but wish I did !

    Troy - a few years back I went to the Cruisecraft dealer here in Brisbane to look at a new 625 Outsider. The guy I spoke to there told me exactly the same thing that CCs did not require trim tabs and his reasoning was that they had relatively little wind heel due to the lower sides compared to other boats. He was a member of the nicholls family too.


    Anyway - that was his theory. I think any boat will benefit from tabs. Anything you do wrong while operating tabs you only do once

    I was going to say that owning a boat can be dangerous, but I think Chimo summed it up very well!
