First board… Terrible build haha.
Seemed alright on small waves… Tried bigger… Wouldn’t turn! At all!

Not much rocker:

Haven’t got anything to measure toe on fins other than to say if you aligned pointing to the nose then they wouldn’t… They’re more straight…
Can I reposition fins and get it to bottom turn?
Have to show some more photos… Try here

Happy that you have a self-made board and are getting to surf, sorry you are having issues.
You’ll need to round out your question with visible pictures and some dimensions to get reasonable answers.
There is a picture button in the reply window that you can use with the Imagur URL to make the photo appear in the thread.
Too bad you don’t have a set of plugs or a Bahne box in the center.
Huck’s recent ‘Huerta’ thread might be of interest too for the whole winged twin trailer thing.
Aloha Jaga,
You’re right ! It is a terrible build. That said, I have to say that it’s on a par with my first build. Were my first build to surface today, I’d deny all knowledge of it ! I think your bottom turn issues, are rocker related, more than fin related. Keep at it, you’ll be surprised how rapidly you builds will improve.
There are two principles turn a modern surfboard. You can make a rockery outline and have fairly straight fins…this allows the board to turn from its rail line. This set up is great in waves with mo juice. Or 2, a board can be fairly flat and have more toe and can’t… This works ok in mushy waves.
Don’t know what you have going on here but I’m assuming that it is a flat rocker with fairly straight fins. And to add insult to injury… You, you, you tried to make a quad, with wings, and a diamond tail…and all that fancy stuff…WTF chuck? While I applaud your vigor to try something extreme…let’s try to get the basics down first. There is a reason why good surfboard shapers are in demand.
Let’s get the shaping dialed in first, fin placement etc. do some research, ask some questions etc…then we will get you buttoned up on glassing and sanding.
So let’s throw that POS away, or reposition the fins into a trifin and see if it will work. /p>
You know the more I look at the pictures… I know I have been catfished. There’s no way someone could have made a board that jacked up. And it has FCS plugs in it…who uses those nasty fin plugs anymore?
So , ha ha… You got me
Glad we see the funny side of it 
I’ll have to get on desktop to add more photos… Though it’s a bit embarrassing to be honest. I was hoping for a bit more of a laugh a the beach but I just got a load of frowns 
I went with as flat rocker as I’ve seen mentioned because I read Bob Simmons say you don’t need it. But… Fins too straight. I’ll drill in some more and retoe them.
Yeah, made so many mistakes. Which seemed like a bad thing St first. But now I think it was really great to make so many mistakes as I’ve learnt so much.
Biggest mistakes were:
Kevlar rails too thick fabric (it was cheap)
Lapped the wrong side first.
No Dowels after laser cut.
Want ahead with too thick epoxy as didn’t want to waste it.
3d printed parts slipped overnight when gluing.
Xps foam too high density.
Missed opportunity to try routing proper fin boxes
Maybe make and glass a single fin on and try it as a single. What do you have to lose :)
Those fin plugs looks like a close cluster to me
Keep at it and have fun
Going by your photo of your bored it looks like it’s got enough rocker and there’s plenty of curve in the outline I don’t understand why it wouldn’t turn the only thing it could be is your fin setup maybe reset both sets of fins front and rear to an inch off the nose each side that seems to work pretty well as a standard.
Apart from that just turn it into a wall hanger
Just checked. It’s more like 2.5-3" from the nose. Oops. Will drill another 2 sets next the the front ones and leave the back as they are.
Tight cluster, faster? In same turbulence zone would make sense; another test to try
TO ME it looks like the fin cluster is way far forward when compared to what most people do with quads. How far forward is the trailing edge of the rear fin?
put a sharp edge around the tail starting3-4" infront of the side fins… That might do something.
10.5" from the tail straight line trail fin
The rail and tail is aboutr as sharp as possible with normalish techniques yorky; 10mm at thinnest. This was a big thing I wanted to try out actually (thick board, thin rails)
So where do I move these fins folks?
Try riding the board with just 2 fins in the rear plugs. Try placing your back foot above the fins or just behind them.
try adding another set of fin plugs about halfway back from your rear set, then use them with the ones at 10.5"… for a board like that fins can be more like 6" and 12" from the tail, or 5" and 11"… not 10.5 and whatever. I’d suggest your rear set of fins be more like a McKee setup rather than near the rail. Try putting them 3" off the stringer, and toed in so they are basically pointed an inch or two off the nose of the board.
Bottom turns died with the birth of the thruster. In order to do a good bottom turn you need to fade the opposite way on takeoff and then lean out and bury the rail.
If you are a 250 pound Hawaiian it helps.
ah but keith if I do that then we got not much toe at the front… and probably not much toe at the back on that setup? maybe I should just drill all 4 again in mckee layout
I think I’ll start by drilling 4 more by the front but toed to 1" off nose
Good idea Keith.
You just may end up with a toed Toad !
Corrected the toe. Better, but seems to want to ride from the nose and not the tail.
I think in my zeal for step deck rails I made the tail too little foam and the chest area too much. In other words, Centre of gravity too far toward the nose.
Live and learn.
