Check out the photos attached let me know what you think 12' long. Sort of a hybrid of a Florida flats boat spray rail, sneak box, and a little old school privateer sheer line with more bow...

what would you add or want different?

Best,

At 12' long I'd be concerned for the lack of freeboard in the rear. I think the transom and midship and rearward sheer needs to be taller. An outboard, a heavy hunter, dog, and gear will find there way in this boat so err on the side of displacement capacity. Thanks for asking for our input. It's great to see someone putting the pencil to paper on a duckboat so-to-speak.
 
I,d bet that bottom design, while very stable would be very hard to drag around in mud. Kind of Boston whalerish.
 
I like it! That bow design, looks like it could handle a chop yet the hull would draft shallow. Add a manual on the fly jack plate and I bet she'd really run in skinny water.
 
I do think you’re on the right track looking at some of the poling skiffs from FL. Although they don’t ge freighted down with a lab and decoys they do need to support the platform and a guy on it at the very far end of the moment arm of the boat’s stern. FL builders have this dialed.
I also concur w Eric’s thoughts on adding a bit of height to the sheer in the stern. Even w the nice combing any extra helps in a stability type test where you lean the hull over hard with weight to one side or the other. And since the motor is already high up in the air on the mount I don’t think you will suffer duck wise once it’s grassed up or covered in a cloth drape.
I do like the line of the classic Privateer hulls. Aa lot of work has been done on the water with that shape. They had a 15’ or 16’ bay boat. You might look at that for influence.
Harry Speers boats for FL fishing are really well thought out also.
Enjoy the process of design and build.
 
I would go a minimum of 14' long. Even most of the smaller marsh boats like 4 rivers, duck boss, momarsh, etc. are at minimum 13'. And even those are somewhat tight when you include 1 person, dog, and gear. Plus it would probably increase your outboard or mud motor rating as well.

I'd like the lines, they are classic yet unique.

I would add a bit more heft to the transom or alternately you could add more rise angle to the decking and serve the same purpose.
 
updated to 14' and made it a little more stout. What do you think are some must haves for the boat? What about canvas spray shields?

How about the beam at the transom? I really don't like wedge shaped boats but it would increase capacity.

starting to look more like a boat and not a low profile sneak box...

Looks a bit like that sailing hull Steve Sanford rebuilt into a sneak bx. in one of his early projects. Think it was the one he found beside dumpster but cant remember the original builder. Might want to check his tutorials for the back story. Might help with your design flow.
 
Must be nice to have CAD skills. I like the 12' version and wouldn't give up on it. Offer both the 12 and 14. In your latest pictures it look like the new version has the max beam moved forward. This is all personal preference but to my eye a sneakbox has the max beam somewhere midship. The transom beam looks fine to me. The cockpit looks a bit elongated. I would bring the rear deck forward enough to offer real storage. Perhaps tiller length on modern outboards with longer tillers. I think a spray skirt is a good idea. If you design it at this stage you can optimize the front cockpit shape to best pair with a spray shield.

I'd like to get a design ironed out on something that a good number of people would want and put it into a made to order production.

I was thinking something between the traditional Barnegat bay sneakbox and a florida flats boat - hells bay/chittum skiff.

Something for two people and a dog that could safely go on open water but also be as small as possible.

I've watched this thread, but not commented because I'm not sure what niche you are trying to fill. More information would be helpful.

I kind of intended something between an estuary duck boat / Barnegat bay sneak box and a Florida's flats skiff... a boat you can take into rougher water but keep it smaller in the two person range with some of the classic features of the sneak box.

I know a couple of spots where people are towing or carrying in the smaller boats I have build to hunt tighter marsh holes off of open water. I was thinking a boat in between size may simplify the process. Going through the open water we have in the sneakbox seems sketchy. I'm sure that is why in our area you don't see any... and most of the Florida flats skiffs are pretty expensive with high demand. The 18' or so center consoles are too big to get everywhere and x marks the spot.

I would like to jig build a couple of different boats first and then maybe plug and mold the best for made to order production. Or that's the thought...
 
That is quite the project, give you credit to work towards it but each one of those boats has its own unique characteristics. Many have attempted a hybrid style of boat similar to some above but unfortunately the design, production, manufacturing and regulations have kept the lid on creativity. As mentioned earlier above Steve Sanford restored a boat called the James Caird with similar lines… Jay Fleming’s boat is stunning I’ve seen it myself In Maryland it’s a tank! Dave also makes one hell of a boat good guy to chat with and get some ideas as well. The Estuary rides like a dream IMG_0806.jpeg
