During our recent trip to the Philippines, Katya and I saw a lot of people on the waterways and even on the open ocean traveling on traditional stand up paddleboards. Seated paddler (squatting) with two-bladed paddle, traveling among the nipa, Balingasay River, Bolinao. Although most people paddle standing using a long single bladed paddle, I have seen some sit and paddle them like a kayak, using narrow two-bladed paddles. Bamboo contains starch which makes it especially attractive as a food source for many organisms, including fungi and insects such as borer beetles.
Our board is totally finished now and we’ve had the opportunity to take her out on a few casual trips. Unlike a sea kayak, which has a cockpit and perimeter lines, a paddleboard doesn’t have a lot to grab on to, so hand carrying and cartopping a slippery, heavy board can be a serious issue.
I think the weight is actually real advantage on the water though because she feels very solid and stable, even in a rough chop. As I mentioned before, I haven’t been on a lot of paddleboards, but I can say that this board so far has been the best I’ve tried!
Anyone who has built a wooden kayak is familiar with hearing plenty of compliments from admirers, and then getting into long conversations with people on the beach about boatbuilding as they are about to launch. If you were thinking ahead you would have carefully marked where the balsa wood blocks were after the bottom was stripped so you would know exactly where you could install the fin box.
When mounting the fin box it is important to have the fin in place, so you can tell that it is perfectly perpendicular to the surface of the board. Simply letting the board sit in the sun for a few minutes will result in an increase in the internal air pressure, as I found out when moved our board from the garage to the yard. We placed a simple vent (also available from Wood Surfboard Supply) consisting of a screw and a neoprene washer at the tail next to the leash cup.
Katya and I caught up with Joe Greenley of Redfish Kayaks at the annual Redfish Wooden Kayak Rendezvous and talked to him about his cedar strip SUP. Joe couldn’t tell us exactly how much his board weighs but we estimated it was about the same as ours, a little over 40 pounds. Although I haven’t been on SUPs enough to really be a discriminating judge their performance, I was impressed with Joe’s board and thought it was the most comfortable board I've tried so far. After seeing Joe’s board I would definitely strip the rails in a single layer as I stripped the hull and deck. After both sides of the board were sealed, we unrolled a layer of 4 oz uncoated plain weave fiberglass intended for clear coating.
Pour the epoxy over the glass starting in the middle of the board and spread it out to the ends.
Now that the entire board has been stripped, it’s time to fair the deck and hull and shape the rails. After the entire board has been sanded with 80 grit paper, we sanded it again with 120 grit. In my previous post, I said that the wooden structure was complete, but I forgot to mention that we still needed to install the nose and tail blocks. The process of planking the hull, or bottom, of the paddleboard is similar to planking the deck but poses a few extra challenges.
Since you will be working with the board lying free and not secured to the workbench, possibly on soft blankets like we did, it is easy to introduce a twist to the board if you are not careful placing the weights evenly and making sure the board is balanced side to side.
The length along the curved bottom of a 12 ft board will necessarily be greater than 12 ft, so your 12 ft strips will come up a couple inches short.
Many paddle boards also feature a notch in the deck which serves as a hand hold to carry the board under your arm.
The deck of this board is mostly flat, but has compound curves which follow the rocker of the board in one direction and the domes of the ribs in another.
All the dimensions you need to build this board are included in the book along with lots more pictures and information.
Unfortunately, the deck on a paddleboard is constantly exposed to the sand and pebbles stuck on the bottom of your feet and booties. This is primarily to hold a pfd on board when we don’t feel like actually wearing one on hot sunny days! Katya has been getting her first taste of that, sometimes talking so long she hardly has any time to paddle!
Because of the curvature of the board, it was difficult to clamp a guide in place.The first few passes with the router were shallow, just used to define the area. The central spar effectively separates the left and right halves of the board into two separate air chambers so it’s important that the vent overrides the spar. The Rendezvous is a casual event where local wooden kayak builders gather on the Fort Worden beach in Port Townsend with their kayaks. I suspect the weight gives it a lot of extra stability compared to the lighter foam boards and is a difference you will really notice in any kind of chop. Since the purpose of sanding with 120 grit is only to smooth out the scratches from the 80 grit paper and not to fair the board, it takes a lot less time. We thought it would be more aesthetically pleasing to have the pattern of vertical rails continuous around the entire board. We used epoxy thickened with wood flour instead of Gorilla Glue, because we anticipated that there would be gaps between the strips, and epoxy is a better choice when you need a gap-filling glue and when joints might be exposed. You can get really creative by combining different woods, stripping in angles or curved patterns, or adding inlays. Clear cedar boards are usually available at your big box home improvement stores in 12 ft lengths. The boards are constructed simply out of a few thick stems of bamboo which are lashed together with heavy duty fishing line to three or four thin bamboo crosspieces placed along the deck. The smaller ones might be used merely as tenders to transport people and supplies from a beach to fishing boats anchored in deeper water, while the longer ones are used for fishing on the open ocean, and usually equipped with a small raised platform for sitting, a fishing net, small styrofoam cooler, and other fishing gear.
One ancient method involved immersing the stems with weights underwater for 3-4 weeks which leaches out the starch. We were concerned that the varnished deck might be slippery and even bought a few cakes of board wax, but it turned out not to be an issue. I bet applying board wax might actually make the situation worse by making the sand stick to the board. Compared to Joe Greenley’s cedar strip board, she’s less responsive to changes in trim (adjusting your position fore and aft), which makes sense because she has a more volume at the ends.
So one final tip: give yourself some extra time when planning trips to field those questions, bask in the admiration of strangers, and share the joy of boatbuilding! After we carved most of the fin box down, we removed the masking tape on the board and ground down the rest of the box lip flush with the board surface with a random orbital sander. If the inside gets wet the strips will start to warp and you would notice it as ridges running along the length of the board.
You could carefully cut, scrape, and sand the glass off and repair the hole with a patch of new glass, but sanding into the wood will result in a discolored area. You might be wondering why can’t we just lay the glass on bare wood and apply a single thick layer of epoxy on it to accomplish all three steps at once: sealing the wood, wetting out the glass, and filling the weave. When they are completely cured, sand the whole board again with the random orbital sander using 80 grit paper to smooth and fair the surface, then again with 120 grit paper to smooth over the scratches from the 80 grit. The outer layer vertical strips were also secured into place with staples, but only at the ends, and stapled into parts of the inner layer that would be trimmed off afterwards.
The last thing you want is to ruin all of your beautiful woodwork by trying to save a few cents on epoxy!
Like the hole for the fin box, the notch will be cut into the blocks using a router after the board is glassed. I expected them to be lightweight but they are remarkably heavy, which has the advantage of greater stability in waves as well as easier handling in wind and when going in and out of surf.
Factory manufactured boards seem to run anywhere from 28-45 pounds so she is at the upper limit but not far out of range.
The sling consists of a couple adjustable wide strips of nylon webbing that snap around the board with quick releases, and another adjustable padded strap that clips in between the other two that you wear over your shoulder. I felt like I had a good grip on the board with neoprene booties on, even in rough water when the deck was awash. I recommend installing a vent to equalize the external and internal pressures, and keeping it open whenever the board is not on the water.
It looked like it was about 30 inches wide and 4 inches thick, very similar to our own board. Unlike the foam boards I’ve tried in the past which couldn't go straight, Joe’s board tracked well even with a light breeze and I didn’t need to switch paddling sides at all. Since we are working in cedar, building up a rail that thick would require a lot of wood and add a ridiculous amount of weight to the finished board. The inner layer strips were then glued to them with Gorilla Glue and stapled and clamped into place. They are glued to both sides of the central spar in the three chambers between the 1st through 4th ribs, using epoxy thickened with wood flour.
Be warned that if you decide to make one of these you may grow to envy those dudes who can carry their boards to the water across big parking lots under one arm without breaking a sweat! The board probably won’t burst at the seams right away if you forget to open it one day, but repeated cycles of high and low pressures will eventually lead to failure. Although in the video I mention that the tracking is stiff, I discovered that shifting your weight more aft makes the board very maneuverable. Another effective way to heat the wood is to shine some hot lights right on the wood surface or, if you are building a kayak or canoe, put lights inside the boat.
Our main exposure to BPA is through food contamination, but it is easily absorbed through inhalation or the skin, for instance through handling thermal paper printed receipts, tickets, and boarding passes.
The blocks are planed to match the curve of the bottom of the board, and the strips glued directly to them. Wood Surf Board Supply sells a transparent traction film that protects the deck surface and provides a nonslip surface. And by standing on the very back of the board and lifting the nose up you can really swing it around quickly. You definitely do not want to start with a cool shop and warm it up after applying the resin. You might find that it’s a great way to meet your neighbors as they stop by to ask what you are building and compliment you on your beautiful woodwork. After the epoxy cured, we ground down the cup edges flush with the board surface with sandpaper. You should use as little epoxy as possible when sealing the wood, wetting out the glass and filling the weave. He lays the board on its side at an angle, and, working through the tail which is still open, uses gravity and a foam brush attached to a long stick to spread epoxy over the fiberglass tape along the inside seam.
Start from one end of the board, and always work from wet to dry, to the other end of the board. Don’t go back over an area that you’ve already varnished: you will leave brush marks because it has already started to dry. There is also an internal structure composed of three longitudinals and a few frames supporting the area in the middle of the board where the paddler stands.
