Early Tracker built Seacrafts

I cant imagine that a flaw that small would make any difference in performance. Can it?
Its hard to tell from the image but it looks like 3/32" to nothing cupped section in a 20" span,.

One might think so, and I'm not sure.
We do know that applying just "a little bit of trim tab" makes a boat tilt left or right, and that the pressure of water drag increases as speed increases.
So........to what affect the hook ?
Perhaps a marine engineer with experience can answer more specifically, while I'll just figure it will have at least some affect, perhaps including fuel economy.

Next part of the issue might be how to best fill in the gap with easiest / permanent solution.

The build quality on mine is good but definitely a bit lighter on the glass than the Potter builds that I have. The transom on mine is solid as well so it looks like Tracker did a decent job in this area. I did have soft spots in the floor at all the console and leaning post fasteners. They used balsa core in the floor, plywood squares in the hatches and access panel on mine. The plywood was rotted and water logged on mine. The Seacraft ride is still there though

Did yours also have the 70 gal tank which was 5 inches longer than the coffin deck opening?
The extra 20 gallons or 140 lbs of weight is forward which I suspect was to improve CG, balance, and ride.

The glass work on my 89 20 is also surprisingly good, but lighter than Potter builds.

Hull shape can also be adversely affected by age/rot and trailer set up.
Bunks which fall short of the transom or too few rollers can do the same thing.

Many BW foam sandwich hulls look like the moon because of this.

I spoke to the owner of that Sceptre I looked at, told him about the hook, and asked him if he'd ever noticed a tendency to heal to stbd at high speed, but he claimed he had never noticed any unusual handling characteristics, so it evidently wasn't enough of a hook for the average guy to notice. Of course the average boater doesn't seem to even know how to properly use trim tabs, so I'm not too surprised by that answer!

Yep mine did have the longer gas tank but it wasn't too get bad to get out of there, pulled it out with my tractor. When I had the new tank made I had them shorten it up by a foot and will shove it all the way forward when I finally get around to finishing the poor neglected thing

In retrospect the hook could be filled in pretty short order with a few layers of glass. I like my Potter but wouldn't think twice about buying an SCI if it can down to it, hook or not.

I am not a Naval Engineer...but let me tell you on my 21 I have volvo trim blades and when you apply one or two lights on (blade down) the boat will do a very fast and notable heel over. When you go aft and look at how far down the blades are ...you would swear they are at least 3 inches...NOPE not even a inch, most likely less than a 1/2".

So there you go....

Thanks for the input........and as you know, " I have a dream" to see a video of this 21 running in an honest 2'-3' chop, from inside the boat, and maybe even from spotter boat !
I can't figure why this hull hasn't been duplicated in an updated version for the hard core fisherman who likes a buddy boat ( like me for example).

My current boat's a beautiful 1996 Wellcraft V21 with Etec 200HO and trim tabs.
I fish mostly the ocean and it's fine for how I use it. Lots of deck space for the size, curtains to stay warm and dry up here in NJ etc....I see the original Carl Moesly 21' as the much bigger brother.
Similar concept, but specifically built for the " more brutal conditions."
I'd gladly pay $ 50 for a demo ride if someone's got one up here in the NorthEast !!

Alim V-20 (Wellcrack V-20) is what Carl out preformed with the Seacraft 21 in the Bay of Pigs / CIA Sea Trials in Miami. You'er scraping the guardrail on the Seacraft learning curve, Bro' - catch up. (LOL)

Your wish is my demand. Mind you it was not white capping but you can tell from the camera shake from my 23 that it was no pond on the way in. Everyone on my boat was holding on for dear life while Terry and crew was sipping cocktails in the 21.
