Custom Built in Our Shop in Maine

We love building boards. It’s what inspires everything we do. And while we're passionate about sharing the process with you, we also realize that not everyone has the space, the patience and the tools to build their own. If you're interested in having us build you a surfboard, there are several ways to start to the process. Putting down an $800 deposit is the quickest. Just close this window, select "Custom Board Deposit" and you're in our queue. For more info on the custom board process, click HERE. Or reach out to us at or 207-457-5313. We'd love to chat with you. 

Putting the Experience Back in Your Hands

For too many years, surfers have felt barred from the act of creating their own boards.  The industry that grew up around surfing after the 1950's (and the industrialized materials brought with it) made it seem like this once common practice - part of every surfer's experience at one time - was out of reach. We disagree. So we've found a bunch of ways that we can help you build your own at home.

Multi-Day Board Building Workshops  

We began offering workshops for people who thought that taking on the building process at home might be a little more than they wanted to take on solo. 

But it's turned out that lots of our students come for other things besides a new surfboard.  And whether they come for the experience of working beside Grain's board builders in our shops in Maine, New York or on the road, for the chance to meet new friends among the other students and our crew, or for getting a chance to try out any of our boards, everyone leaves with a board they built themselves.  And that's pretty great. Check out our workshops HERE.  

HomeGrown Kits

Most of the boards in our line are offered as complete DIY kits, designed for you to tackle at home. Kits contains all of the material you need to build your board, plus a 170 page instruction that walks you though each step of the process.

If you’re good with your hands, can work carefully with an attention to detail and follow written instructions, then you’ll love the feeling of dropping into your first wave on a Homegrown Surfboard Kit you built yourself. It’s indescribable. More information our kits can be found HERE.  

Hard Copy Paper Plans

If you don't need the guidance and support that comes with a full surfboard kit, we've developed a complete set of plans printed on plotter paper that will get you well on your way to a great board. 

Paper plans include full-scale keel and frames, nose and tail templates, board outline, and a few construction detail notes. These represent the inside shape of the board, accounting for a 1/4" plank thickness to be added back to the board. We also include a 46-page guide that covers the high points of the building process. More information on our paper plans can be found HERE

Keel and Frames

One step above paper plans, our frame-sets save you the cost of buying your own plywood and the time of making all those intricate cuts, but still allows you get creative with your own woods. 

Each frame set includes full-scale keel and frame, CNC cut and numbered from 1/4" marine ply, nose and tail templates, construction detail notes, and just like our Plans, includes a 46 page instruction manual that covers the high points of the building process. Break the frames out and assemble them by number and you're off and running. More information can be found HERE

Downloadable Study Plans 

We’ve noticed over the years that a lot of our customers, especially those overseas, get stuck dealing with high shipping rates. To help get around that, and give people one more resource to help turn their dream project into a reality, we’re excited to offer downloadable Study Plans for every surfboard shape we offer as a DIY product. Just select Study Plans from the drop down menu, check out, and you'll have your plans at your finger tips in just a few moments. 

Note that these Study Plans are not just an inexpensive form of our other DIY product - no wood is included, nor are there any instructions. Study Plans are just that, full outside cross sections, profiles and outlines of the final shape of the surfboard, a perfect tool to get more familiar with the board shape you’re dreaming of. More information on our Study plans can be found HERE
