Recently I have been experimenting with a softer, more rippling look to my seas. My Repulse and Prince of Wales builds each use the same technique. For rougher seas, I've outlined other ideas here:
viewtopic.php?f=4&t=155661It is a nice alternative to plaster or epoxy for smooth, gentle ripples. Here is how I have done calm water with plaster:
viewtopic.php?f=4&t=156538 Honestly, the method outlined below trumps my efforts with plaster or epoxy for neatness and ease of execution. I think the look is better as well.
These builds both use the method described below.

I start by using pink styrofoam. Of course, if you don't care about the V-shaped wake mounds going back, you could apply this technique to any flat surface. For example, you could trace your waterlined hull onto a flat piece of MDF, mask off the footprint, do the stuff described below, and slice around the mask to remove it and you're done and ready to put the ship down. Anyway I trace my waterlined hull shape onto the foam and use a sharp blade to make a slice deep into this line. I don't remove the foam where the ship will be until the sea is carved. It's just easier and less risky for wrecking the edges where the removed foam would be. Using a large tube (about 5 inches wide) covered in very coarse sandpaper, I carve the V-shaped wake that trails back and away from the ship. At this point, I'm just going for a perfectly smooth ocean with a couple of big swells moving back. No wavelets or anything like that. The waves come later. I basically sand back and forth to create 3 troughs on either side of where the ship will be with my big sanding tube. I then carve down the rest of the base so that the areas in front of the ship and behind are at the same level as the lowest part of the wake. The tube ensures perfectly straight mounds. I then sand the ocean perfectly smooth by hand with some sandpaper and refined the v-shaped mounds. This diagram shows the troughs I sand first, then the areas that need to come down. The tube makes it very even and smooth. The tube is also useful for creating deeper, undulating rough sea swells.

I finished this by coating the sea with as many as 12 layers of artist's gesso (basically white acrylic paint) which I then sanded. Always add new layers by brushing in the same directions (with the waves). Sanding this in between coats makes it better. With water, the more layers you do the better.
To create the wavelets, I used the following technique:
Artist's acrylic gloss medium has a unique viscosity and behavior to it that makes it perfect for making calm, undulating wavelets. The consistency is somewhat like white glue, but a little more runny. You don't want it running like water, but it has to hold it's bulbous form after you apply it. It self levels, but holds it's shape in a rounded way. This is what you want. I recommend using a high quality gloss medium; either Golden or Liquitex. A cheaper brand might dry with slight wrinkles or splits. Test first.

I use a flat synthetic brush that is about as wide as my finger to do this.

I load up the brush with a fair amount of medium. It has to form a blob when you put it down. The medium will shrink a fair bit once it dries. Make good, mounding blobs. Don't attempt to accelerate the drying process by using a fan or hairdryer. The blobs will split and ugly things will happen. Also, don't fiddle with the blobs once they start setting. Scabbing and other unwanted skin-like things will happen. they're hard to get rid of later.

You are now going to create a series of eye-shaped blobs onto your flat ocean surface. Each end of the eye-shape should trail off. Ensure that they are running parallel to each other. You might draft out some pencil lines to keep things more or less square before starting.
At this point, the eye-shapes must not touch! keep them about a half an inch from each other. In theory, this is all fine and perfect, but in real life, your blobs will sometimes deform over time as they sit due to gravity and flow. Monitor your blobs at all times and make little corrections to them. One thing that does happens is that a part of the blob will flatten out into a round bulbous circle in the middle or end of your eye shape making a tadpole shape. This is something to be avoided as it just doesn't look water-like in the end. It's a simple matter to just brush on either side directionally with the other waves to smear off the offending bulges.
You are not trying to cover the whole sea, just put down as many as you can without having them touch. Note that the medium will spread out a bit so allow space for this spreading. Again, they must not touch.
Once these are dry, you are going to add more eye-shapes in-between the ones you put down. It doesn't matter if these touch the dry ones.

Once these are dry, you are going to add more eyes in -between the ones from the last two sessions. Let this dry. Add more eyes, let that dry, add more eyes.... etc. Eventually the whole sea will be filled up with your eye shapes.
Once this is done, look at and see if it is perfect. By perfect, I mean ultra smooth and free of any sand-like lumps coming through from the base etc. Sand it all over if you have to, re-coat, add more eyes, just layer the hell out of it with nice water-like forms and layers of acrylic medium (applied with the direction of the waves of course) until it's a thing of beauty. You could coat the whole thing with several layers more of the acrylic medium once you're satisfied. Lots of layers really adds up to a smooth, undulating look. During the build of the ship, I just keep my sea out in the open and add a few coats every time I'm bored in the evening. Once you're satisfied, all you have to do is paint it one single color and finish it with your wake effects etc. The result is ultra perfect and smooth. It looks natural and not hand-made. I always finish my seas with many coats of Liquitex HIGH gloss acrylic varnish. Note: this is not the medium I use to do these effects. The High gloss varnish is ultra shiny and runny like water.
Here is a link to a thread where I demonstrate how I finish my seas with cotton etc.
viewtopic.php?f=4&t=157503&p=637868#p637868It is also possible to use the gloss acrylic medium to make an even gentler sea.
Simply apply the acrylic medium with your brush as one continuous field working back and forth with thick amounts of medium. You're basically applying it in a daubing motion from left to right so that there is a subtle sense of direction to the ripples.
When I do this, I'll do the sea once this way, let it dry, then do it again....check, re-coat, apply numerous layers etc.
