looks like torque roll causing this?

Thanks guys.
I might see is I can run at lunch today. Rain coming in tho.

Take care of yourself. I have never had stones but I do know plenty of people that have had them and it sounds very painfull.

Keep this thread updated when you get a chance. I am very interested to see what can be done with this hull.

Will wider (2 1/4) trim tabs stabilize the boat?

[JPriami]

Ive been wondering about this with the trim tabs. If someone has them I'd say give it a try just to find out if it helps or hurts. because I hear some say and reading that you need two sets of trim tabs on a vee. the outter set are for cornering & the inner set are for ride attitude and fine tuning. But I also hear some say and read that a good boat doesn't even need trim tabs.
So just to put caution to the wind and find out by trial and error. maybe they will or wont. Lets find out.

Well, I have a set coming. On mounting them, shouldn't they be flush with the bottom of the hull? The stock spartan tabs are slightly above the bottom of the hull. Should they be centered between the strut drive and turn fins or biased one way or the other?

[JPriami]

It's to my understanding that trim tabs should be just a little above the bottom of the hull. So how they are on the Spartan is correct to my knowledge. I had that same question. But I did a bunch of reading and even reading on real vee hull setups with trim tabs. And even on a real vee hull it's recommended that the trim tabs be about 1/2" or more above the bottom of the hull. So on scale that would just be a little bit on an rc but looks about right on the Spartan. It has something to do with the fact that your just using the back edges of the tabs for correction. I won't go into grave detail.

The tabs need to be above the bottom. Thanks.

As JP has already pointed out, there are differing opinions on trim tabs.

I read one opinion on the spartan, that because the vee is so deep when it comes onto plane at high speed it will be high enough out of the water the stock trim tabs will be running basically dry.

This individual suggested a second set of tabs closer to the strut would help provided stability when the hull is high out of the water.

If you look inside the hull you will see there are specific moldings in the plastic designed to hold mounting screws coming through the transom. It might be advisable to try to utilize those mounting points if at all possible.

JP had posted a photo of them early.

Yep, i recall the posts and photos. I've identified the tabs and it's going to be a tight fit. I won't know for sure until I have them in my hand. Thanks for the input.
