Do trim tabs need to be adjustable?

[Blahst]

I've been looking around for trim tabs but most now seem to be electrically or hydraulically actuated i.e. bennett & Lenco. Are they not available in an adjustable bolt form? i.e. use a spanner to adjust.
I'm running a Mod VP type tunnel hull but think that trim tabs will help a little at lower speeds with porpoising but I'm not terribly interested in spending a fortune on trim tabs that i can adjust in the drivers seat.
Or am I going about it all wrong :confused:

There was a discussion about this a while back, and to answer your question, yes, you can do that. You might want to search and see if you can find it.

spend $30 on doel fins first to control low speed porpoising. i have both but only use the trim tabs for real low speed planning for skiing
