Tabman,
What options do I have for this type of boat hull. I have a set of m120 sport tabs on my old boat, not sure if theres a way they would work, if I moved em to this boat.
Boat is a 22'6" panga style hull. Thx for you Help!

Yes that's going to be a challenge! Do you have a picture of the stern from the side of the boat>

Okay there it is. Its about a 13 inch difference in the transom "difference" (if you will). I saw another company that makes tabs, that starts with a L and ends with a O. makes a 12x12 for 17-30 ft boats. I guess not even 12 is enough. Is this going to require a ccustom deal?
As you point out the "difference" (it looks closer to 14-1/2" to me) is going to rule out finding a stock Tab with enough chord (fore to aft measurement). Also with the actuator (ram) positioned on the trailing edge of the Tab the standard strokes of Lenco or Bennett will yield a reduced amount of deflection, although the increased surface area of a longer chord will make up for that a little bit.
The next issue is the height of that little step before the overhang. It looks to be 1/2" - 3/4", that's not enough room to mount the hinge plate for a Tab. The hinge plate would have to be installed on the bottom and screwed up into the hull. This can be done with any brand.
To attach the actuator to the transom you will need to position where it attaches to the trailing edge of the Trim Tab far enough aft so the cylinder body does not strike the transom when the Trim Tabs are in the full down position.
Also with the long chord the Tab will need to be reinforced to prevent cupping. One way to do that would to bend the sides of the Trim Tabs up 1" to increase its rigidity.
I know that we (Bennett) don't have anything that will fit and I suspect the same for Lenco.
On way to proceed may be to find a fabricator who can custom make the Tabs and by the rest of the components from a Trim Tab manufacturer.

Ouch thats what i was afraid of.....Ugh!
Any ideas of who to talk to?

I know its a different company....Wondering if the mounting bracket portion would fit on the small vertical flat portion. Maybe a little trimming lol
Also the (step) that the hinge mounts too actually ranges from 1 3/8"- 1 1/2"......I don't know how wide it really needs to be for a hinge mount.
And would not fit under the overhang. So it would be best to check first.
We make some Trim Tabs that are 16" fore to aft, but you can see how big the hinge is and its not made to fit under the boat. Also note the location of the actuators:
I think itr's pretty much the same for Lenco:
I think the smallest height hinge plate we make is about 1-5/8" and I would not recommend it for a Tim Tab laonger than 12".

Thanks for your help tabman as always!

And well lenco makes a 18 X 12 tab Part no 10638-101
Its a complete special order/custom deal....You have to ask for it etc. through a dealer. Its their special "panga tab"
Price tag about 1k with switch, etc. I am not sure tabs will make a thousand dollar difference, but I don't know.
wish I had other options, just thought I'd let you know

haha I'm sure to some people.....yes. Unfort I just can't afford it.....It would be nice. I strapped a doel-fin on and replaced the prop (which was needed anyway) Thats made a good difference. I think tabs would help me in the 3+ seas and for side to side listing....but oh well.
