Calling All Surf Flap Experts (that is you, Duffy)!

[dakota4ce]

Yesterday was the first test of the 2006 Tige Frankenstein 24Ve. Quick reminder of everything done:

1. Removal of factory ballast stuff
2. Centralizing of Batteries et al
3. Enlargement of Rear lockers all way to transom
3. Install of custom sacs and pumps--1800ish# port 1600is# stbd 600ish# bow (and 200# in lead for good measure)
4. Rework of cruise control--elimination SpeedSet, addition of a new throttle setup and a Hydrophase RideSteady
5. FAE install and complete exhaust re-routing (muffler removal)
6. Trimming of "lip" on factory swim platform
7. 1235 Prop
8. etc etc etc (such as a witty naming of the boat)

So I took it to a local puddle close to town to test it--it was windy as heck, and the lake varies in depth from 10-18'. Filled surf side full, filled bow mostly full, put lead on surf side, set cruise to 11.5 and went about it, varied TAPS all over the map.

Offe we went. I thought wave size was impressive...overall though, I was PLEASED AS PUNCH that the throttle worked perfectly, the cruise worked perfectly, the pumps all worked perfectly, the boat listed like it was going to sink.....shockingly all worked!

KINDA DISAPPOINTED THAT COULD NOT GET WAVE TO CLEAN UP. Looking for top level suggestions on how to get a clean wave? What are your first thoughts? Admittedly, I was giddy that it simply worked and was overwhelmed with variables to test, so "science" was poor for this session.

HOW ABOUT A SURF FLAP?

Lets chat! Here are the photos: why the heck are these sideways??!! Please crane your neck to see them.

It's a multidimensional game of varying the speed, AND the TAPS, AND shifting weight around. Takes time, fuel, and patient passengers.

There are also some tried and true general principles that apply to a certain hull, hopefully I can squeeze some of these gems out of you experts out there.

Mainly also, wondering if a surf flap is a no brainer?

[WYTige?]

Glad everything worked out for you, gotta love those results. I'm sure more will chime in here, but I've heard depth of the water will sometimes jack with the wake. Not sure if that's your issue or not. Again, well done on all the DIY mods.

FAE is creating the extra wash via the rooster tail it creates. Need flap or no FAE.

[dakota4ce]

Boom! A strong opinion, I love it. I will fashion a flap and give a whirl.

The other thing to consider, platform trimming.

My first thought is try some off side weight and let some out of the bow.

Thank you, I will also mess with that. I just need to go to the lake by myself, with a notebook, and do some science.

Do you have a factory platform fiberglass on your Ve?

Yes I still have the stock platform.

I have a 22Ve with the factory fiberglass platform, no modifications. I have found lots of weight on the surf side as far back as you can and no bow weight. I know many may say add ow weight but so far it hasn't helped me at all. I have the FAE and no flap.

LOL. Apologies for brief, abrupt answer. I suggested the flap because it worked magic for me and it was less than $50. My setup was super simple too so that helped me. I've read lots of posts on different forums of people correcting surf wave related FAE problems with flaps. My guess is that the wave looks cleaner at 1 or 2 than it does at 4 or 5. The FAE creates a whole other dimension to the water flow already coming off the transom then the taps plate. Just my .02 man. I'm sure there other solutions to it as well.

I am going to the farm store today for flap component gathering. Seems like a no brainer to try to me!

Dakota4ce, were you running on Okoboji...? if so where the lake has a lot of areas specifically on the north end where a sandbar runs across and impacts the wave a lot. I would also try to maybe add a little bit of weight to the opposite rear corner of the boat...you're right the best thing that you can do is head out with the notebook by yourself on a nice day and a ballast bag or two to simulate one or two people and have at it!

I am running a "FLAP" on mine, and it makes a huge difference. There are some variables to take into account though when building one.
1. Mounting-Most are mounting to the swim-step
2. Depth in the water-not just resting but while underway, if you set it for a resting position you will get to much water that goes over the top and does not work as well.
3. There is not as much pressure on these tabs as some people may guess. All you are really doing is lengthening the hull on one side to make the wave converge at a different point behind the boat. My "FLAP" is 24LX10W and makes a huge difference. I only have about 30lbs of pressure on the plate, so no worries on stressing the swim-step.
4. Speed for what I have noticed the speed with the tab is a bit faster, my wave really cleans up around 13-15.
5. My one and only issue, they can be big and heavy, you have to usually get in the water to put it on and you have to take it off when running full speed.

Hope this helps, I posted a few pics of mine on here under the Direct Surf file.

Ohh I also forgot to mention, if you are using a "FLAP" I Weight my boat evenly. Makes it quite a bit safer to run more weight.
