Displacement Hull Surfboard - Designs

Before I actually started shaping Displacement Hull, I layed out the design and shape I wanted for the board. It was originally going to be a pintail, but then decided to change it to a diamond tail. The link below is a PDF of the designs I did for this board.

The Baby is Born: Displacement Hull Surfboard

All done! Wow, quite an experience! Definitely learned a lot and found a whole new level of respect for all those shapers out there that do this for a living. Kudos to all you guys.

Ready to take it out!! I'll post some pictures as soon as I find someone to sit there and take some photos of me. Bummer it's really small here in SoCal right now.


Not much to say here. Not much fun. Wet sanded with 240 grit, then 400 grit and finally 600 grit. Although after sanding away that shininess, it was cool to see it come back once I started polishing it with the compound.

The only thing I might of done differently is wearing gloves while hand sanding. I didn't wear them sanding the gloss because I wasn't concerned with the glass ichies. But I ended up sanding some of the skin off my finger tips.

The Icing on the Cake

Sanding is all done and now goes on the gloss.

Here is the Gloss Mix:

Gloss Resin: 24oz
Catalyst: 15cc
SA: None
Pigment: None
Env Temp: 73 F

It kicked about in about 15 minutes. It looks like candy right now - shiny and all. Hopefully it will stay like that when I polish it.

No more sanding please!

I am getting a little tired of sanding. It has been a little frustrating for me only because I keep on sanding a little too much. You'll notice at the tip of the board that I sanded the black off. Jeeeeez! Got to do more touch-up work.

Here is a picture of the leash loop that I just glassed on. As you can tell, it needs some SANDING. Jeeeeez. Anway, I am pretty excited about this because this is going to be the first board I own with a glassed on leash loop. All my other boards have that drill through fin box thingy. That is nice and all, but wanted to try something different. I hope the placement is correct and won't get in the way.

Here are some shots of the most current.

I think I am getting pretty close in completing the board. This weekend I will be doing some final sanding and then to the gloss. If all goes well, I'll be surfing this board soon. Can't wait!

Adding the Last Pigment Color

Get the Fin Box In.

I made this template using some left over pegboard and raising it up a tad using some left over balsa. The cut went well. No problems cutting the hole. I used a 1/4 inch router bit with the DeWalt router. Had to make the template pretty low because the bit I used wasn't long enough to cut out a 1 1/8 inch hole.

I needed to do shallow cuts. Probably a 1/4 of an inch at a time. It was weird, any deeper than that, the sound it made was intolerable although it cut just fine.

Ready to Sand

Displacement Hull

Here is an image that gives you an idea of the curvature of the bottom hull.

All in all the kick times seemed alright. Freaked out a little bit at first only because I didn't know what to expect. I would kick it slower next time as the lam job started to gel a little and would of like to work the lap tucks better. It started to gel in less than 10 minutes. After I was done with what I needed to do, I used a heater to cure the lam and hotcoat faster.

The kick time for the hotcoat was fine. Just noting that it had 3 teaspoons of pigment in it, the kick times would be faster if there was no pigment. After reading some threads, I think I did the lam job too thin where the glass looked dry. This is why I think I got pits and zits in the hotcoat.

I probably should have installed the fin box after the lamination, but I think I will do it before the gloss coat. Plus I am trying to spread out my spending. I still need to get a 1/4 inch router bit, a router template bushing and make myself a template.

So having said all that, now I'm ready for some sanding. Kind of dreading this part... But Jason over at gave me an awesome deal (like always) on a DeWalt 7” /9” Heavy-Duty Electronic Variable Speed Polisher! Should make things easier. I will keep you updated.

So So Shiny!

Hotcoated the other side. Love the drippies - except when it's on my skin.

I knew glassing was a messy job, but geeze! Definitely need a drip tray for the next glass job. The stuff tracks everywhere - And you were laughing at my floor lining.

It's Hotcoat Time!!!

It turned out to be a lot easier than laminating. I ended up using 3 teaspoons of white pigment to get it a little more opaque. Seems to be just the right amount.

Here is the Hotcoat Mix:

Resin: 32oz
Catalyst: 25cc
SA: 10cc
Pigment: 3 teapoons
Env Temp: 76 F

Another Photo Before Hotcoating

What a Mess!

Who spilled the milk?

This isn't what you think it is. And no, I am not lactating!

I should call this board "The Nipple".
Hmmm - From this point forward, it shall be called THE NIPPLE!!!
Jason, stop salivating!

Lamination Complete

Laps cut and finally ready to move on to the hotcoat. I think I should of used more pigment in the lamination resin. I only used one teaspoon and it still looks transparent. Maybe with a white haze.

Cutting the Laps

After the lamination hardened (still tacky - maybe 3/4 way cured), I started cutting the lapsThis is what the cut laps looked like.

Now masking the laps for the other side.

Laminating the Bottom

Alright, the bottom lamination is all done. Sorry I didn't take pictures as I don't have anyone to take my action shots.

Anyways, the idiot I am.... I wasn't wearing a shirt and those wonderful resin drips that fell all over my arm, started burning! Enduring the pain until I finished, I ran over to the acetone to clean the drips off. Again, idiot.... Come to find out that acetone takes everything dissolved in it right into your bloodstream, through your skin!!! Hopefully I'll survive.

Here is what I mixed up for the resin:
Resin: 40oz
Catalyst: 10cc
Pigment: 1 teapoon (white)
Env Temp: 76 F

After laminating, it didn't seem like it was gelling like it was suppose too. Like I would really know - I have never done this before. After reading all those threads regarding the resin not kicking, I started to get a little concerned that it would never harden. But, it was doing what it was suppose too. It wouldn't be burning my arm if it wasn't. Just to be sure, I ended up bringing down a heater to elevate the temperature a bit. It probably got to about 79 degrees.

Glassing Prep

4 oz E glass trimmed and ready to go. 1 layer for the bottom and 2 x 4 oz for the deck.

I actually used a laser printer on the rice paper instead of an ink-jet. It would of worked better if i would of used a better laser. Mine didn't print blacks too well - weird since it's only a black and white printer.

Here is the resin with white pigment added to the one on the right. The left one is there just in case I need to mix more in a hurry.
