Trim Tab Help needed!

Unread post by Gotofflucky »

So the boat is a 1999 Searunner 22. I would love to try some trim tabs on her, primarily to minimize the roll, especially in chop. Also think some fuel saving might be captured as well.
The issue I have with current configuration, is that there is not much room back there.
Between the main, trolling kicker, transducer, etc. seems like a lot going on there already.
Boat does not have a pod. Short of adding one, I’m thinking the only way is to extend aluminum tabs outboard? Suggestions? Anyone have any experience with “SmartTab” products?

Standard transom owners are sort of stuck, especially if you've got dual transducer brackets and a kicker, this is the primary reason our ProV doesn't have trim tabs.

Ok, so I did some more research and found a product that I was willing to try out…Nauticus “smart tabs”. These are automatic tabs, which use water pressure to compress a nitrogen filled actuator (shock). No power, no hydraulic pump. I chose to purchase the “low profile” tabs, which are stainless steel 6” x 9”, but substituted the 7.5” shocks that come with that kit for 10” standard shocks ( 60lb pressure) in order to avoid the hull support beam weld on the transom of my boat. Had to install somewhat midway between keel and edge of hull, so lost some efficiency there, but was told by the manufacturer that the tabs will still perform. One needs a minimum of 10” distance from the main engine to the tab placement…I went with 12” which gave me a similar distance from my transducer. It is busy back there but all is installed and seems to work, although I have only been out once since install and it was a bit choppy. Next trip out before storage I plan to adjust the tabs for a small permanent list to port. May be a possible option for others with the standard transom.

Looks very good. Wish I had the skill and equipment to do something like that. Mirror control between the main and kicker was what pushed me in the direction I took. Be interested to see how how you accomplish that!
