Re: Proper placement of trimtabs
Generaider, just as everyone else has suggested ….. I posed this exact question directly to Tom (tabman) awhile ago …..
I had asked about size and mounting options …. As I did not want to go across the lifting strake ….due to the variable deadrise. As I recall the first recommendation was for an 18” tab …as calculated on the website…hence what I wrote below From the centerline to the first lifting strake its about 15.5 " then to the next strake 14.25" and then to the chine 15.25". I also snooped around and found some other 23's with tabs. Basically they all looked to have a 12" span but some had a 9" chord and other a 12" (Seacraft 23 inboard and a 24 Silverhawk had the 12"). and to quote his response ….. “…..the 12" x 12" would be the better choice, it is more in keeping with our guidelines and the space that the strakes allow. If you choose the 12" x 12" you would be happy. I would suggest that the M120 will be a better choice. It provides about the same amount of lift as a 12" x 12' due to the fins on the sides. They capture water pressure that normally escapes out the sides of the Tab and channel it aft for additional lift. The M120s come with a Rocker Switch Control as standard, and the pre connected hydraulic fittings will make it easier to install. You can mount either the 12" x 12" or the M120 in 3" from the chine and run the Tab right up to the strake. I have marked what I mean on a copy of the photo you sent me, it is attached to this e-mail.” I would have to assume that these suggestions still stand ….. Tom is a great person to deal with … and helps in anyway he can

Re: Proper placement of trimtabs
You mat want to check out Lenco Tabs. They are very easy to install and do not use any oil. This means no pump to mount in the boat. Bennett has been out there for a long time and make a great product so no matter how you go youll be ok.

Scott is right about the 3" from the chine. But Be aware that if you should go bigger than the 12"x 12" (not recommended) or mount closer to the centerline you could cause interferance with transom mount electronics when pushing your bow down. [img]images/icons/shocked.gif[/img]

Re: Proper placement of trimtabs
Capt chuck ...so true about the 18" tab ..... That's what prompted the question to Tom .... and once I clarified the application with Tom about the SeaCrafts hull configuration ... with the steps in the hull's bottom changing deadrise angles .... The 12" was the max to go with

Re: Proper placement of trimtabs
Just got off the phone w/ Tom and he felt that the lift is nearly the same between the M120 and the 12 x 12 and the M120 is easier to install. I almost went with LENCO because the design sounded simpler and less to install but my boat is going to be in the water all the time and stuff grows like crazy down here.
Bill If one is good the two are better.

Re: Proper placement of trimtabs
Bill,
I enjoyed speaking with you! I have to visit this site more often [img]images/icons/smile.gif[/img] The M120s or the 12 x 12s will work great, but as we discussed the M120s will mount easier and will fit under the bracket. Let me know if you need anything and I will be delighetd to help. Thank you very much for choosing our Tabs! Tom McGow Bennett Marine
