I have a question about this specific design. Most of these 20s look to have the sheer break close to mid-ship. But a couple, this one included, seems to have the break about 1/3 from the stern (as they should). I always think the break is too far forward, but lenm's example here is absolutely perfect. I think Shay built one that had the sheer pulled back also...not sure.
So the question is, are there two different plans? The boat in this thread is as fine an example as has been presented.

I like that you filled between the strips/side stringers. Some folks leave them as-is or they sheet over them leaving the interior hollow. The foam core adds a ton of strength with minor weigh penalty. It's a good strategy. A good friend of mine builds his sportfishing boats that same way.

Beautiful rig. That is also one huge top on there!

Typing from the bleachers here...
One of the main advantages of using carbon is for weight savings. The stuff is very expensive in comparison to glass. To me, it doesn't make sense to use carbon (especially alot of it) in a hand layup. Unless you are very good at epoxy work, you are almost assured to use too much resin...which will negate the weight savings you were hoping to get from the carbon in the first place. I feel that carbon fiber should be bagged in order to gain it's full advantage.
My other "issue" with it is the fact that it's so stiff. One of the best attributes of a wood boat is how it rides in comparison to a "glass" boat. It just seems that some of that soft wood feel would be lost with carbon in the hull skin. Maybe that's the wrong way of thinking, I don't know.
With all that said, you can get an aramid/eglass blend that might work better for you. I suspect that it would be less expensive than the carbon weave. Regardless, you may want to consider adding glass over top just so you don't have to deal with sanding over aramid.

Trim tabs will give you the performance enhancement you're looking for. Yes, it's alot more work than bolting on a fin...but it's a better alternative in my opinion.
-
It's not just the light weight of cold molding the boat...it's that she has a bottom that's easy to shove.
-
Good to know that monofilament on the dock trick is alive & well. Ours fell off a while back...need to get it back up.
-
Nice looking job. With those built in reverse chines you should not need to add spray rails (add on chines). That's pretty much redundant if you do.
-
You have a very nice bottom, sir.

Where will you be staying? Remley's Point is a good ramp with plenty of parking. Shem Creek is popular, but parking is a bear. There are other public ramps...just depends on where you are going to be.

The Carolina Bow is a pretty common feature on this type of boat, so not any real theft, as it's been well done, if not overly so over the years. The broken sheer is also a fairly common feature and also not a surprise. The bracket has a number of logical reasons behind it's shape and a designer of Dudley 's skill wouldn't need to copy anything.
Agreed. The styling cues are common...and just like the lines of a Carolina hull, there's only so many ways to integrate a bracket.

Looks awesome!
Post up some #s once you get them.

It's almost spooky it's so good...

When it comes time to fair the hull (before sheathing) I would apply some kind of guide coat to the surface such as a light dusting with some contrasting color of rattle can primer (it doesn't take much) or spritzing the boat down with a spray bottle solution of denatured alcohol with some red food coloring in it. The alcohol evaps away leaving the light pigment on the surface. Then once you begin sanding all the small low spots will jump out at you and you can go in with a wide putty knife and apply microspheres to each area, then fair again and it should be ready for glass. You can repeat the coloring again if you wish depending on how far you want to take the surface.
That's what i'd do anyway.

This is what I've seen done countless times. Thanks.
I mentioned this a while back on another boat building forum and was blasted for even suggesting that any faring material go under the glass. I shook my head & kept quiet (which is a struggle for me...).
-
What is the consensus when it comes to fairing the wood before glass? I know some guys do it...the wood is easy to fair down, and you're not taking much.

Double post...

Opinion #1,257...
She looks great! Absolutely beautiful.
I also feel she sits ok. Certainly not "bad"...and definitely not bad for the first hull with twins! I would not be against using her as she is, but testing with some ballast is also a good idea. I would suggest getting her to the final stance before tweaking the engine (height, props, angles, etc.). As several others have already suggested, I would not put dead ballast 100% forward. Maybe some there (Lotus' suggestion of a longer/heavier anchor chain is a darned good idea), but further aft for the bulk of it. Also, I would not go full flat. Keep in mind that if you're fishing, you'll likely have several hundred pounds riding forward of the console (coolers, boxes, ice, people, etc.).
I seriously feel it will take less ballast than you expect. If you don't already have an anchor, put a real one (read: heavy) up there with a chain that's a size larger & twice as long as you planned on using. At that point I'd put your largest cooler up front and fill it with ice...then see how she sits with no further ballast.
Best of luck...she's beautiful.

Looks outstanding.

Looking great! What size bilge pump is going inside the bracket?
-
That basic shape, without the wrinkles, is really nice. It'll be sharp if you can get it to hold.
-
If possible...IF...find a trailer guy near you that will put one together specifically for your boat.

I hope you and your family are safe after the earthquake.

Thank you very much for your answer, Mr. Graham. In the past, I would have talked with our friend Buck about these design intricacies over lunch (since I fed him nearly every day of the week) ... but none of us have that pleasure any more. It, apparently, is more optical illusion than anything else. I can't imagine a better example than what Len has produced. Thank you for your information.
