I just bought a Tahoe 234 23' deck boat and it has a 5.0l mpi 260hp engine and a bravo 3 drive with dual 26p 3 blade SS props. I love the space available on this large boat, but trying to plane out is sometimes difficult when we have a group of 8 people of the boat and I really don't want to change the pitch of the factory props.

I have purchased a hydrofoil and it has helped, but now I'm looking at trim tabs. I've just joined this forum and have read that a bunch of people are using smart tabs, but I'm wondering if it would be better to go with Bennett hydraulic trim tabs for this size of boat. Any recommendations?

Re: Trim tabs electric vs smart?

I agree, lose the foil, it causes extra stress on the motor. Where are you boating? Do you use the boat the ski or wake board? I have been running smart tabs on my 8000 lb 254 Chris craft for 2 years and they are awesome. They are sized to the weight and length of your boat. No need to install hydraulics or electrical and no need to have room for a control pad. Nauticus tabs will cost you about $125.00 for your size/weight boat. Smart tabs properly installed are always working to keep your boat in the most efficient attitude, where helm controlled tabs require you to do that!

I would recommend Helm control tabs if you were running on the ocean with following seas and bad inlets. I'm guessing with your style boat, you will mainly be in protected waters, rivers, lakes, and maybe a few beach visits. I would also recommend helm controlled tabs if you need alot of weight distribution tab adjustment while running.

Simply put, it depends on your use and what you seem is better for you. I personally think that the smart tabs are the best bang for the buck.

Thanks QC! I just found another thread in this forum on the same topic. Apparently this is a common question, just missed it at first.

Maybe a dumb question, but I'll ask anyways. I did a search for helm adjustable tab on iboats and just found the Bennett controller. Is helm just the design and should look for the Bennett non-hydraulic, electrical tab? Just want to be sure and any links for recommendations would be great.

Thanks for your quick response!

Re: Trim tabs electric vs smart?

To chris,

Other than cost, why would you not want almost infinite control of shifting loads, and speeds and conditions? On any boat, any size?

To Alex,

Helm adjustable just means to me that you have switches at the helm. Lenco's, Bennett's and some others are all "helm adjustable". Bennett customer service is extremely good. I'd go that away except the Lenco install is easier.

Chris,
Yes, I mainly run my boat on Canyon lake, but thinking having the ability to control my boat if one side is leaning is nice. I'm mainly asking since people have tried both and would help me outweigh the nice to have vs being practical.

My boat is a little over 4000 w/o fuel and people and was wondering if I went with smart tabs, would you recommend stepping up to the model rated above 4700? I did a quick search and was thinking I might be on a boarder between two smart tab models.

QC,
I really appreciate your help. I'm new to boating terminology and will contact them directly if I decide on adjistable trim tabs. Still not sure which way to go just yet, but this is a good discussion.

Was the hydrofoil a waste of money?

Re: Trim tabs electric vs smart?

To Alex -Your best bet is to contact Nauticusinc and ask them which size to get. But I would say, you would want the ones that are above 4700. Once you add your fuel and people, you will want the bigger size. They do adjust to different positions. The leaning issue is something that has been debated for a long time.

Say you are cruising and have a 1/4 sea or wind coming from the side or a person decides to walk to one side causiong the boat to lean. These are all senarios that you could use helm controlled tabs for. The problem is when you controll it to act as a leveler, the minute the condition changes, you have to change the tab setting again.

I won't sit here and say that nauticus tabs do what helm controlled tabs do in that manner, but what I will say is nauticus tabs will help your boat ride more evenly all the time, they constantly adjust.

I rather have my tabs adjusting for me, than me having to adjust my tabs. But thats my choice and opinion. You really do need to decide whats best for you. Here is a great read and information at this link.http://www.nauticusinc.com/pdf/nauticus_smart_tabs_tech_info.pdf
I recommend that link to anyone that has questions on hydro foils, trim tabs or motor trim. You can learn alot from this no matter what tabs you decide to buy. Good luck with your purchase and enjoy. Any tabs you buy will greatly help the performance of your boat

To QC - why would you not want a trim tab to constantly adjust improving your performance always! Why would you want to have to constantly adjust your tabs manually? By the way, I've run lenco, bennett and Nauticus. They all have there place, I think on the op's size boat and where he will be boating the Nauticus tabs provide more benifits than the others. The fact is, it all depends on the boat use. Smaller boats usually will not see the type of use that larger cruisers do. Smaller boats are usually used for shorter spurts, skiing, wakeboarding, fishing, etc, These boats run all over the place. Where a larger vessel is more of a destination type boat, cruise from one location to another location etc. They are just used differently. My parents houseboat, will never be used for wakeboarding,lol I know thats extreme but you get what I'm saying.

I agree with Chris the smart tabs are plug and play. Put them on and forget them no driver interaction required. I installed them and they work exactly as advertised and it only took 30 minutes to install them.

Re: Trim tabs electric vs smart?

I love Smart Tabs, and I have installed and operated them. Also Lenco's, Bennett's and K-plane knock offs. I will say that anyone who says that SmartTabs are better has not used adjustable tabs. Ever have anyone move to one side of the boat and cause a list? Ever have a cross wind cause a list? Ever wished you could get your boat to squat with the bow up to keep down spray? Ever wish you could drive the bow down harder into some chop? Ever wish you could lift your tabs on the trailer? Ever wish you could have a little more tab or a little less tab at ANY condition? If you have answered yes to any of those questions you would LOVE helm adjustable tabs.

I completely understand loving what you have and what you are comfortable with, but one thing is consistent, those who argue that Smart Tabs are "better" have never used helm adjustable. You cannot have had the level of control they offer and call Smart Tabs better. Just not possible ;)

Edit: BTW chris, of all the boats being discussed here, including your parents houseboat, the one that would benefit the most from helm adjustable tabs is, uh . . . yours :eek: :p ;)

Re: Trim tabs electric vs smart?

Qc, do I really need to go into all the things that nauticus tabs do that helm controlled tabs don't? I mean really man, there two totally different animals! I agree that Nauticaus tabs aren't better than helm controlled tabs in all areas, but they do out perform helm controlled tabs in most performance areas on boats under 26 ft or boats weighing under 8500 pounds. To say either is better or worse than the other wouldn't do either one any justice because they do different things. Yes they do some of the same things, but they do it very differently! The buyer needs to decide whats better for him, and what pros and cons come with which tab. There is almost always a down side to anything, both helm controlled tabs and Nauticus tabs have down sides in the way they operate or don't operate in various conditions. Nauticus doesn't claim to be better for larger boats and doesn't claim that there tabs do everything that helm controlled tabs do. But hlem controlled tabs companies can also not claim that there tabs do what nauticus tabs do.

Nauticus tabs weren't designed to level the boat out when the heffer goes to one side of the boat. Although they do keep your boat alot more level than without them. They were made to improve performance in a wider range of areas and be hands free and improve performance numbers drastically in most areas. Yes, the helm controlled tabs are going to be better for high load changes on the boat from side to side. The helm tabs are going to be better for a list period or in a following sea.

But now lets look at the areas that nauticus tabs excell over helm controlled tabs. The tabs are self adjusting, meaning they are working from the time you leave the dock to the time you get home. Positioning themselves to give your boat the best running attitude at all times. Helm controlled tabs rely on the captain to be the effecient one and do that! You lose performance with helm controlled tabs anytime the tab is over positioned or under positioned, which is pretty much all the time because the water pressure/waves are constantly changing. It literally would be impossible for someone to adjust helm controlled tabs as fast as nauticus tabs are self adjusting. Again nauticus tabs probably adjust more in one minute than most people adjust there helm contolled tabs in one day.

Nauticus tabs are great for there targeted market because of what performance they bring to the table. And no, I don't need to adjust side to side motion on my smaller boats. Nauticus tabs do that for me to a certain degree.. Only time my boat really leans hard is if I am at rest with two or more people standing on one side or the other. Your helm controlled tabs aren't going to fix that either. I also don't have and have never had an issue trailering with any tabs on any boat!? If your having that issue it is probably a poor trailer setup. Also, if you had used these like you claim, you would have seen that you can still control bow up and down attitude by adjusting the trim on the motor while still having the stability of the tabs. If the Nauticus tabs are sized properly and adjusted properly to your size boat, you will very rarely, if ever, wish you had more or less control of them. Thats why they are great and people love them. They do what they were designed to do plus some!

If I ever lived on the ocean again or had to go through rough inlets or had to deal with a tremendous amount of following seas, then I would consider having helm controlled tabs again. But for the best performance over all, I will choose Nauticus tabs every time.

Qc, you made the statement that most people that run Nauticus tabs have not ever run helm controlled tabs. I can make the same statement but in reverse, because most people that have run helm controlled tabs have not run nauticus tabs. Heres the real question, why did you install and run Nauticus tabs if you believe that helm controlled tabs are the way to go??? What kind of boat was it on? And what kind of changed performance numbers did you get running them? Just curious! :D

I installed them on a friend's boat:

1) He is a point and shoot kind of guy. Really shouldn't even own a boat. He is that inept with switches and steering wheels and drive trim and wind and waves etc. But the tabs make him a safer boater.
2) He was trying to correct a porpoising situation.
3) I've piloted the boat a lot.
4) It slowed top speed, but definitely improved hole shot and eliminated the porpoise.
5) I recommend SmartTabs for those who are also point and shoot types, or if the budget is the main concern or if ease of install is the main concern.
6) There is nothing that SmartTabs do that cannot be duplicated by helm adjustable except them flying down when the hull leaves the water as in the picture on their website. Explain why this is good and I will retract my statement . . . :)

Re: Trim tabs electric vs smart?

$450 Bennett hydraulic trim tabs were the best addition to my inboard outboard I've ever done.

Benefits:
1. Accelerates from a stop like it's got 50 hp more.
2. Boat will plane off @ 10 mph while sightseeing.
3. Makes the boat ride like it's 4' longer--if you drop'em slightly @ cruise speeds in wavy conditions.
4. Can level the boat laterally when all the fat women sit on one side.
5. When you're up to speed and coming up on a big gut wrenching wave, you can drop the nose down for a second, plow thru the wave, then raise the nose back up.
6. Doesn't drag at all when retracted up--no loss of speed or use any more fuel.
7. Very easily owner installed--doesn't require a mechanic.

Every planing full hulled boat should have them as standard equipment. (They're not required or used on bass boats, flat bottom fishing boats or pontoons, however.)

Re: Trim tabs electric vs smart?

This is silly. Smart tabs are great. Adjustable like my Bennets are BETTER than Smart tabs, no doubt about it.

I ran about 15 miles in pitch darkness the other night and stayed on plane at a slow speed where no Smart tabs could have helped.

I also have used it on windy days when the wind and current are working against me. Smart tabs can't do that.

I've also used it to pick up my wife's side a bit when she's catching spray, she appreciates that. Smart tabs can't do that.

Some of us actually like to be in control of our boats ;)

Re: Trim tabs electric vs smart?

I love it when people mention all the things that helm control tabs do, because Nauticus tabs do so much more. Basically a helm controlled tab is a leveling tool. Nauticus tabs are a performance tool.:D By the way, if I did run bennetts again, I would be looking into there automatic controller. ;)

Wrong again. Why are you so adamant that Smart tabs are BETTER than Adjustable tabs? They are NOT, plain and simple.

Like QC said, it's for people on a budget. No way I would put smart tabs on anything over 18' personally. Maybe you should hire a captain to run your boat for you! :D

LOL, You keep saying smart tabs do so much more, they don't do anything more or better. Sorry, admit defeat and move on newbie!

I like to debate when I know I'm right:D

Why are you so adamant that helm controlled tabs are better than Nauticus tabs? They are NOT! Plain and simple. ! Neither one is better than the other for all sized boats. There not for people on a budget, I spent 12 g in upgrades to my boat, do you think I was worried about a few extra hundred dollars. No, your wrong to make that statement! By you saying that, you are saying that anyone that buys nauticus tabs is cheap or can't afford "real tabs"! I just have to laugh at that one!:p

First place, maybe you should actually go back and read my statements, at no time did I say Smart Tabs were better than helm controlled tabs all the time, for every boat, or in every condition!! I did say they are two different animals. They don't do the same things! Yes they do some of the same things! The helm control tabs like I stated before will excell over Nauticus tabs in certain areas, but nauticus tabs will excell over helm controlled tabs in other areas like better performance.

Give me the numbers! All you guys that say nauticus isn't as good, give me the numbers! I know exactly what the tabs did for my boat because I ran a test with and without them on the boat. The proof is in the performance.

You are correct when you say, I said the nauticus tabs do more, (in the performance areas). It is not possible for any human to adjust helm controlled tabs (manually) fast enough for them to be beneficial to performance all the time on your boat. Unless you have invested heavily in automatic controls for your helm controlled tabs, it is impossible for you to adjust them as fast as nauticus tabs adjust on there own.

Skier and fishing - Lets say you are getting on plane, then you slow down, then you speed up, then you turn, speed up again, slow down, stop, start planing again,stop, plane, turn, slow down, throttle to wot! How many times would you have adjusted your trim tabs in that scenario for best performance????? Ohh, by the way, you will need to be adjusting them while you are driving the boat, moving the throttle, watching for on coming boats, looking for debris in the water, watching your skier, and paying attention to other people on board etc etc etc. I have to do non of that while adjusting my tabs because mine adjust on there own. The point is, my tabs are constantly adjusting to put the boat into the best running position saving me fuel and making the ride better. Your helm controlled tabs rely on you to do that!

Helm controlled tabs Like I have said have there place. They have been used for many years and will continue to be used, but they are better on certain boats, just like nauticus tabs are better on certain boats.

You sir, are the one that is wrong if you think that helm controlled tabs do the same thing or are better than nauticus tabs in all areas. It simply isn't true and is impossible for them to change to conditions fast enough to be a performance gain in most areas. That being said, nauticus tabs will fail in comparison when trying to level out a severe leaning or in a following sea. But thats about where it stops!

Must be nice to be so closed minded and think you are right about it all. Also must be sad to have been on this forum (O ld Salt) for so long and not learned a thing about what Nauticus tabs bring to the table. Enjoy having to control your tabs and getting the most efficient attitude out of them! Meanwhile, I will enjoy being hands free while my tabs are doing there best to improve the boats performance all the time by themselves.:D

By the way, the newbee card doesn't work unless your talking to someone that is with out much boating experience.:facepalm: I've only been operating a boat on the water offshore and inland for almost 30 years. Again, like I said, show me your performance numbers before and after your tab install, then we can compare how much efficientcy your getting from your tabs.

Its easy to come on here and talk about what you think you know, but its better if you actually know what your talking about. Have you ever had Nauticus tabs on a boat you owned, ran, and tested? If so, show the numbers! Why sir would you put them on a 18 foot boat and under? Why? Because there cheap? That to me shows your ignorance because there are many very expensive 18 ft boats on the water and many people that are not worried about the cost of trim tabs.


By the way old timer, responding to your earlier post, nauticus tabs allow your boat to plain at a much slower speed, thats part of what makes them great. While allowing that they are also doing it with much less rpms per speed.

They also adjust automatically to 1/4 seas or if the wind is blowing they have already and continue to adjust to the pressure it is putting on your boat. Thus giving you a better ride.

Also, you said you adjust your boat for spray, I don't get spray on my boat hardly ever. Maybe its because the style boat I have or just maybe its because my tabs have the boat in the right position to start with instead of me having to adjust the attitude of the boat with helm controls to prevent spray.

Smart tabs do alot more than you think by always putting the boat in the best running position. Do the helm control tabs help more in some situation, as I have already said, yup! But the pros of the smart tabs "imo" outweight the pros of the helm controlled tabs for my boat.

As I stated in my first post here, the OP will have to decide whats better for him and his boat. I assume he will take everyones opinions and make the choice thats best for him.

Sorry, admit defeat, and move on old timer!:D

Good Lord, OK, you are right, I will remove my Bennets tomorrow and throw them away, then I will pretend like I can't afford real tabs and put Smart tabs on. Sweet!

Seriously, you sure do talk a lot with absolutely nothing to say HAHAHAHA
