Have a talk with John at Nauticus- he advised me pretty well on my boat
- I have a 29 footer and weight is 2300kgs. The ones you adjust -from what people have told me seem to be a pain to say the very least. Nauticus have a
a new range out - and they sent me the correct ones for my boat- which are in fact 2 activators /tab. Results are pretty good - have done about 42 knts ( not 52 jonny fuller - my mistake) in a 5/6 and the plain is constant. The cost was about 260$ FOB tampa- and you can get them direct from Nauticus

Hi Eupa,

I have in fact reinstalled my Nauticus tabs. I prefer them over the Lencos for sure.

Ollyit,

your setup looks exactly like mine. Everthing looks good.

I've had trim tabs on bigger hard boats and as far as I'm concerned they correct trim, as the name implies. On a larger boat where the load (people usually) might be unevenly distributed( sat to one side chatting) a trim inbalance can be corrected using the tabs. This does though create drag, hence I'm no fan of the things. There is the argument that they give effective extra hull length for speed. Not convinced on that one. As for correcting handling problems. I would look more at engine/boat set up.

hi mollunum,

We ( boastser and myself) are in fact talking about the "automatic" ones made by Nauticus in the states( www.nauticusinc.com)- i fitted them becasue I could never get a decent trim on the boat- and its simple to see why. I have 29' of boat with 420 kgs sitting on the back and a cabin in the middle. the total weight of the boat is 2300 kgs- there is no way that you can trim that out to give you a decent ride- with the engines alone. The engine trim area is miniscule

Fitting automatic trim tabs -they adjust themselves whilst moving ,serves two purposes
- it lifts the stern up
- at a certain speed they cease to act as lift and become stablizers. Drag does not seem to come into it

Its like a Boeing - these are the identical to the horizontal stablizer and act in exactly the same way - but havnt seen a Boeing on the water yet???????

Jonathan

I have to agree with Eupa,

I have noticed a real improvement in not only the ride of my boat but also the fuel economy. Although the Nauticus tabs seem like the "conventional" trim tabs they are anything but that in operation.
