Building a boat is no easy task. It is summer, and you feel like plunging into an adventure with a self-made boat. However, there are a few obstacles that you need to overcome. To extensively indulge with every nooks and cranny of the building boat process, you may require insurmountable knowledge and a scheme.
For those of you who are novices, plywood automatically becomes your first option among all the materials available. The valid reason being plywood tends to be very cost-effective and holds increased stability and strength.
Moreover, due to plywood’s inherent ability to being resistant to excessive impact further makes it a better choice.
There are many factors that loom over the building of a boat. This article will help you guide through all the essential aspects to turn your dreams into reality.
Essential Factors to Consider
We are all aware that building a boat using plywood is not only an inexpensive alternative but also a lightweight option. However, few elements need discussion before fabricating perfection.
First and foremost, ensure where you will be sailing like Popeye, the sailor man. Different types and sizes of the boat allow you to understand the mechanism; however, all of them are intended to safely and smoothly maneuver you through the water bodies.
Chiefly, there are two types of water qualities you will encounter. Firstly there is freshwater, and then there is saltwater.
Both of the water types require minimal maintenance when it comes to boating. Saltwater boats demand a little more nurturing than freshwater boats.
If you are an avid sailor for both water bodies, you can always opt for building a saltwater boat and use it in freshwater since saltwater boats are capable of withstanding harsher conditions compared to freshwater.
If you prefer to download the free programs available on the internet, go ahead. A good idea helps you design and construct not only an ideal boat but also aids in saving money and time in the future. This particular factor is considered to be one of the hardest decisions since there is a range of designs accessible to you.
Furthermore, if you are someone who has zero faith in free plans, then you can pay a professional to design a high-profile boat that you can make without any effort. Some of you may hold the idea that the less you pay for something, the inferior standard it will eventually be, mainly when there are expensive choices available.
Building a boat out of scratch may seem like a good idea at first, considering how profitable it sounds. However, the core materials utilized in hull and deck construction must be of top-notch quality for various reasons.
The selection of equipment is directly proportional to the performance and efficiency of the boat. Improved sustainability must be ensured before assembling your boat.
For instance, if you are thinking of painting your boat, make sure you get excellent quality paint instead of the cheap ones. The quality of the colour must be superior since longevity is a huge factor.
Retaining gloss, smoothness, and finesse can only be achieved through the right variety. Plus, surface adhesion is an additional benefit of good quality paint.
Marine Grade Plywood
When you are talking about exceptional grade plywood, the only term that comes to mind is marine plywood. It is manufactured by the superior standard, resistant to tropical water hardwood as well as top-grade veneers. If you are worried about any flaws, these materials take care of it. Prolonged exposure to water may cause harm to your boat. However, marine plywood is both moisture and waterproof.
Marine plywood includes fir, meranti and Okoume. This type of plywood consists of layers that have no breaks, and will not de-laminate. Moreover, boats are prone to fungus infestation, however with marine plywood you no longer have to worry about fungal issues. Both affordability and versatility are ensured with this specific type of plywood.
Those of you, who are rookies, must be quite unsure about the epoxy resin and its mechanism. It is the building blocks of making a boat. The manufacture of this material occurs through the chemical reaction of two or more industrial compounds.
Epoxy resin is fundamentally shaped by reacting bisphenol with epichlorohydrin. Ensuring the best quality epoxy resin available holds the highest priority.
There are a lot of resins available in the market; however, epoxy resin is the best among all for various reasons. Epoxy resin makes the boat water-resistant by enabling it to absorb moisture, to withstand the harshness of aqua.
Moreover, this resin has a more exceptional surface adhesion and can hold out against wear and tear. Along with durability and a strong façade, it offers a lightweight structure for you.
Fiberglass is considered to be of low maintenance since it can withstand abrasion and makes the cleaning process much more manageable. Moreover, coating a boat with fiberglass may seem like a hard task.
However, the process is as simple as possible. Most builders can mould fiberglass with clean lines. The clean lines ensure the boat glides through the water effectively and efficiently.
Fiberglass also helps cancel the noise of water splashing onto your boat. It provides you with a smooth and quiet continuous motion as you cruise around the place.
Some boats tend to be structurally damaged with more prolonged exposure to water, but a coating with fiberglass lets you keep the boat in the water for several months.
Boat Building Process
Since you are well aware of the essential aspects and ingredients involved in making a boat, you are ready to indulge in a significant process. The construction incorporates a technique of boat building named stitch and glue method. There are a few steps to get the boat you desire finally.
Plywood comes in 8 feet panels only. If more extended panels were to be found, you would most likely have a much easier job. However, it does not take a lot of effort to attach sheets to achieve a longer one. This entire process is known as scarfing.
If you already hold a plan, then this gets significantly easier for you. First of all, make sure you cut two plywood panels into a pointy and knife-like manner. Both of the similar pieces are then glued together using epoxy resin. Remember, plywood generally has a good side. Flip it before you start cutting.
Before you put the glue in and after cutting the edges equally, you must sharpen the sheets properly. The sharpening procedure includes a belt sander, and the aftermath consists of a smooth and even plane from top to bottom. However make sure, the panels remain straight and parallel.
You must provide a good sanding to your plywood either by a grit paper or through a sheet sander. The sanding process results in a polished surface for the glue to hold on.
During the gluing task, mix the epoxy resin with powder and lay it out evenly. To cure the epoxy, position the wax paper properly on top of the joint, and secure the joint with weight to hold the scarf firmly.
Since you already own a plan for your boat, the first of many obstacles has been overcome. The next step follows you to estimate and sketch several parts of your plywood attentively. The plan provides you with every angle and measurement required.
Before you assemble the boat, all these marks, measurements and reference points must be incorporated in the plywood using small nails, pointers or even markers. This process helps you determine the arrangement of many vital aspects, including the centerline, the placement of seats, the position of the centreboard.
The following step involves you fragmenting the parts into the actual ordeal. You can use various saws to cut the plywood in perfect shape including jigsaw, circular saw, and Sawall. Remember to cut out the parts in a slightly large manner since you have to further sand the plywood for refinement.
However, if you are worried about making errors while cutting, then throw your worries to the wind. The epoxy resin allows you the freedom to make minor errors, as epoxy can fill the mistakes.
To further ensure complete accuracy, make sure by laying out your plywood properly and inspect by comparing all the measurements and markings.
The subsequent step requires you to drill your plywood in numerous places. Although before the drilling procedure, ensure the diameter of your wire at first since the width of drilling will be slightly larger than the wire.
Your plan will guide you through the drilling process, which tells you where to drill and where not to drill.
You have many options of material when it comes to wires, including copper and steel. However, remain extra cautious with water since corrosion can appear any time with these wires. Stitching or wiring allows you to assemble your boat and take pride in your creation.
Before you start stitching, decide on what length your wire must be for you to be comfortable with it. As you have already drilled the holes, you only need to slide the cables inside the holes. After insertion, bring the wires and put the ends opposite to each other and twist it firmly.
Since you already have a plan, you stitch and assemble your boat according to it. Adjust the panels and start the wiring action with finesse. After you are done with your stitching procedure, you open the folded sides and erect your design while making sure the alignment and accuracy remain optimal.
After ensuring the stitching method according to your plan and adjusting the plywood to the right position, you dive in with the epoxy glue. A minimal gap is required to make sure the glue settles in nice and slow.
Before smearing the glue, measure the boat side by side or diagonally. Both parties must be of the same length.
Also make sure the boat is level from the front, plus the back. This factor will inhibit your boat from deformation. Once you make sure of the alignment and its uniformity, then apply the epoxy glue throughout the boat to ensure perfect semblance.
Powder-like substances such as silica or fibers are added to it, to make the glue more concentrated. The thickness enables te the glue to not have the water-like consistency.
It should be the right amount of thick to apply the glue-like butter. However, it may take some time to adjust the thickness but do not worry; it is not a tough task.
After gluing your boat correctly, make sure it is positioned correctly. Let the epoxy cure, which assists in the hardening process. When the process completes, and the epoxy settles in, your boat will be in a fixed and firm position. Meanwhile, you can pull out the wires.
You will be required to fillet your boat once you are done with the previous task. A fillet is thickened epoxy, which increases surface area and provides surface adhesion. Not only does it offer strength to the joints but it also hides any mistake that may have been made during the assembly.
Fiberglass and Paint
As we have already mentioned before, fiberglass cloth is a crucial aspect of building a boat. After putting the fillet, you can immediately jump to fiber-glassing the boat.
The fabric is placed in the boat; make sure not to pin down the material since it will stick to the fillet. You will be required to spread some epoxy consistently across the boat without putting pressure on the fillets.
Make sure the viscosity of epoxy remains constant at all places. Remember the wetness of the cloth does not matter; however, if the resin coagulates, quickly spread it around before it settles in.
The motion must be fast as well as tender to achieve absolute perfection in your work. Do not worry if the fabric lifts; just maintain your movement.
After you are done settling the fiberglass cloth, you will most certainly opt for varnishing and painting. Make sure to use top quality paint to acquire supreme results.
As for varnishing, remember to remove the marks since it will not cover up while you varnish. The drilled holes must be filled with epoxy resin to keep the boat waterproof.
Finally, you are done assembling your boat made out of plywood. Through patience and impeccable refinement, all of you will be able to do the task. It does not take much effort, making a boat is as simple as it sounds. Now you may paddle your way through the water.
