Just a note to say the Q tabs work really well on the 31 and look good compacted against the transom vs the way standard planes stick out the back.

Unfortunately you will not be able to use the excuse that the tabs cut the line and my fish got away.

Can I take that as an endorsement? I have a 25 with single 330B Cummins/v drive. Would like to get the bow down a bit and trim side to side. I like the idea but can't confirm how they perform. Any input would be helpfull.
Thanks,
JG

I have them on the B20 and will be putting them on the 25. Easy to use, intuitive, quick, simple install, etc...

Thanks for the input

James, I love your 25, I looked over pictures on BD and Scot's web page. The only possible complaint I could have is the space behind the console to the transom. Since you looking to get the bow down, I am wondering if you feel you could have put the engine a little farther forward? I read all the explainations on Scot's page, but would like to think (hope actually, as thats a project I am interested in) it could move forward more. I am not by the way knocking your 25, it's the nicest by far that I have ever looked at, just more cockpit would be even better.

Appreciate the info. I've wondered for about a year if they performed as advertised and hadn't heard of anyone actually using them. The other day I stumbled onto this pic while searching for ql trim tabs:

I was surprised to see the name of a charterboat I know, a 46' Carman, Never-E-Nuff. I first-mate when not in school on a few of the other charter boats on the same dock as Never-E-Nuff in Solomons, Md. I asked Captain Shaun about them and he says they've been great.

Bruce, what size is best for a B28?

I've always thought that these were cool.... they work on the "separated bubble" theory, not unlike a pickup truck's tailgate. But I've never had any access to someone that had practical experience with them.

If I am correct (?) - when down, at slow speeds the Q tabs will create drag, but at planing speeds they will behave no differently than regular trim tabs.

Based on your actual experience, does that sound right?

Do they work electrically?Are they wired? Walter

Walter,

The QL tabs are hydraulic, electrically operated pump, same as Bennet. For more info see: http://www.qlmarine.com/ql.asp

The main components of the system are:
– Interceptor units.
– Control panel.
– Control unit.
– Plug-in cable harnesses.

Features:
– Easy, safe and exact manoeuvring.
– Less drag.
– Quick response.
– Built in trim sensor.
– Control panel with LEDs for precise trim indication.
– Automatic retraction.
– Electrical actuator, no hydraulics needed.
– Electric components “sealed for life ".
– Designed for several helm stations.
– Suitable for multiple installation.
– Composite material, no corrosion.
– Quick and easy to install.
– Small dimensions, light weight.
– Complies with CE and ABYC requirements.

Many factors affect the choice of properly sized trim unit configurations, and the ultimate responsibility for selection is up to the boat owner. These sizing recommendations are based on average performance. Your choice may vary based on power, engine configuration, weight distribution, type of boat and use. When making a choice, please remember that the largest interceptor configuration that will comfortably fit on the transom will be the most efficient. The QL Boat Trim System is designed to fully replace conventional trim tabs.

A B25 in the 25Bertram forum has them installed and he really likes them so take a gander at his posts, he's Eli.

Sorry Pat but no hydraulics. All electric.

Blade comes down out the bottom 90 degrees to the body "intercepting" the water creating drag.

Sorta like air brakes on a plane.

Apparently there is some limit to speed. 50 knots I think.

Any curved transom will require wedge blocks.

The last 31 I did, the owner likes to run fast in rough seas. Needed the bow to come down more to cut thru and splash him more on the bridge.

Didn't like the Bennet sticking out. Said he would have to add a platform to cover them up.

Saw them on the back of Gerry's 31 at my shop and liked the idea. I hadn't sea trialed Gerry's 31 so I didn't have any experience with them so we took a chance and they worked great.

Owner's from Randall's neck of the woods.

Like Bruce said I have them and they work great.


QL control on the bottom right.

How many do you have on each side of your deep-V stern? Walter

wow....thats a nice bridge

Walter,
If your referring to Gerry's, its one unit per side.

Any pics of what they look like mounted on a deep-v?

I have one on each side. Sorry no photos at this time. Thanks Randall.

Pat,

Thanks for posting the pics.

you're welcome ...what material are the hatches and under dash panel made from......clean.....i love clean....no screw heads or nothing...are the other two hatches full of electrics?

Capt. Patrick, what are the two metal things above the drain in the transom? Zinc? Dynaplate? As I put my B28 back together I have more and more questions...Thinking about it, my b28 had the dynaplate on the bottom. Re-installing it on the transom would reduce some drag, however minimal. After blasting, filling,fairing, barrier coat, and new bottom paint on my Stamas 26 I picked up 2 knots.

I need to re-read the bonding page in the boat-building tips, but does the dynaplate get wired in to the bonding system? I'm just learning about bonding/grounding and the difference between them.

Looks to me like drain plug / zinc / light

Scot is right, drain/zinc/underwater light.
Randal: storage on the other 2 compartments, no more electronics, clean & simple. Made out of fiberglass if that is what you are asking.

These photos are turning this into a boat porn site! Very, very nice boat in those pictures.

did you notice the two guys talking on the side of the boat?

That thing is so shiny it's a mirror!

And it's gelcoat, not paint...

Gelcoat Wow that is a nice Job!
Actually it looks like 3 guys talking Very Impressive to say the least.

Good eye Sean

On average what would one expect to pay for a set of the QL 450 tabs?

Dug

Dug: I do not remember, sorry.

I think the average price is 650.00
