IT FINALLY GOT WARM ENOUGH FOR THE FIRST ATTEMPT OF THE YEAR IN KENTUCKY.

WATER WAS 67 DEG.  AND HAD DECENTLY CALM WATER.

 

 

 

I HAD 2 EXPERIENCE GUYS BEHIND THE BOAT THAT SURF VERY WELL.  WE PLAYED WITH THE BALLAST AND TRIED FOR A FEW HOURS TO DIAL IT IN.

I DO NOT HAVE TRIM TABS, OR TRIM ON MY 21 TOMCAT TO START.

I AM NOT INTERESTED IN INSTALLING IT.

 

WITH THIS SAID I WANT TO GET THE BEST SURF WAKE POSSIBE OUT OF MY BOAT AND WAS LOOKING FOR SOME HELP, OR SOMEONE EXPERIENCED WITH THIS BOAT.  I HAVE HAD SEVERAL BOATS, AND THIS IS MY FIRST MB.   I AM JUST TRYING TO SAVE A LOT OF TIME DIALING IT IN.   ANY HELP WOULD BE GREAT.

 

I FILLED THE PASSANGER SIDE FACTORY FULL.

PUT A 1100# BAG IN THE SKI LOCKER AND ABOUT 625# FROM THE AMPS RUNNING TOWARDS THE BACK OF THE BOAT UNDER THE SEAT.

 

 THIS WORKED PRETTY GOOD BUT THE TOP HAD A LITTLE WHITE ON IT AND THE POCKET WASNT AS LONG AS EXPECTED.

 

I THEN FILLED THE RIGHT SIDE UP HALF FULL AND DIDNT MAKE MUCH DIFFERENCE.

 

 

WE HAD FUN WITH THIS, BUT I KNOW I AM NOT GETTING THE BEST POTIENTIAL OUT OF THE BOAT.    WE RAN OUT OF DAYLIGHT AND THIS IS ALL WE GOT FOR THE FIRST OUTING.

 

 

THANKS FOR THE HELP IN ADVANCE.

bow weight and start with both factory tanks full. withoutsomething to knock down the wash your best bet will be adding bow weight to adjust the running angle and draining non surf side stock tank from full untill its clean.

Welcome to the forum!

 

my summary is that you have wash, don't have a trim tab, don't want to install a trim tab.  

 

Your options are:

 

do a "duffy flap," (http://www.wakeworld...ad.php?t=787204)

 

get over it and install a trim tab,

 

live with the wash, or

 

sell the boat.

 

(and yeah YOU DON'T NEED THE ALL CAPS!)

with out a trim tab or a flap its only going to be clean to a point. I run a flap and for $40 its an easy thing to mess with. before I had the flap I noticed adding bow weight cleaned up a lot of the wash. imo you can live with it if you dont want to add something to the back of the boat. the wash is enhanced with to much bow rise hence adding bow weight will tame it... to a point.

What did you use for a Flap? I am trying to clean up my F21 Reg side and need a bit of assistance...

Thanks in advance

Thanks SD,

I looked through and didnt see MFGs comments anywhere. I see Duffey used 3/4" horse stall mat and the other Tiga used 1/2", but I kinda wanted to know what MFG ran and make something similar....

you are gonna need to come down to the wco and see it in person

duffy had the original idea but stopped once the fae spray was gone. others have taken it to a level of wave shaping and wave stability that duff didnt... imo the "duffy flap" only applies to fae spray compensation.

I'm not saying his shape is the only way to do it, but peeps have been using his idea to clean up waves, not just mitigate FAE spray.  I wasn't trying to say "must use this particular shape."  LOL I guess I'm just giving him props for coming up with the idea.

Yeah, like everyone said, bow weight is a must. As for the spray, it would be very tough to clean it up without a trim tab or a flap on the regular side.

 

Ask Greeko, he tried and ended up installing a trim tab

I installed a trim tab and it helped HUGE!

 $1200 - $1500 Dealer installed (includes the very pricey and proprietary brain box that allows gauge reading and auto retract)

 

or

 

$300 - $400 for DIY (you buy the plate, actuator, switch, and misc wires and hardware and do it yourself (no auto retract and no gauge indicator) but not really necessary IMHO.

And there are several threads on this forum where people have done the DIY trim plate. Some good info to get you started.

 

here is one of the more thorough ones

MFB, do I have to compete at the WCO? I understand this is part of the Endless Wave Tour but everytime I tried to register, it prompts me to register for the comp.

 

My skill is quite limited and rather not compete.
