Think of a loaf of bread from which you might make toast. One end is the bow, the other end the stern of your “boat.” Better yet, imagine four loaves of bread on your kitchen counter. Cutting one loaf of bread like a normal person does results in stations through the loaf of bread (your hull). Stations define the shape of a hull section at any point from bow to stern. They are viewed from head-on, as though the boat were coming right at you. Since the loaf of bread has the same section shape from “bow” to “stern,” all the cuts through the bread will be the same shape. Such is not the case with a hull, unless it’s a barge. Usually we divide the hull into 10 stations from bow to stern, beginning where the tip of the bow intersects the waterline and dividing the hull into equal stations from there to the transom. here

I received a question out of the blue from a friend in the auto industry the other day. He asked, “When you are designing a vessel and approximating the final weight and hull surface area, do you know where the waterline is going to be? I suppose the answer is yes, but how close? And do you know how the vessel will sit in the water before it actually gets wet?” more

Cutting the third loaf of bread vertically, like you would a cake, provides buttocks. (Or as Forrest Gump would say, BUTT-ocksss.) These lines are viewed in the hull’s profile, indicating the rise or fall of the hull bottom from bow to stern. Buttocks are a critical indicator of a hull’s speed potential. A high buttock angle in the aft half of the hull (usually coupled with a lot of curvature) limits a hull to not much more than displacement speeds. Sailboats, or tugboats with deep bilges amidships and very shallow draft at the transom, are examples of boats with high buttock angles aft. These hulls are incapable of high speeds unless they are dropped off a cliff. more

Understanding the basics of how water flows beneath your hull is imperative to buying the right boat for your needs. here

Since he’s affiliated with Ford’s design studio, I have to wonder what the next Mustang is going to look like after a question like this. [links]

Once this mathematical exercise is complete, the boat must be built so her actual center of gravity matches the designed center of buoyancy of the hull. Archimedes’ principle being what it is, the submerged volume and center of buoyancy will match the weight and center of gravity of the floating boat, so the designer and the builder should work in concert to come as close to the planned center of buoyancy as possible. This is the only way to ensure the boat will float “on her lines,” not down by the bow or stern, or generally too low. here

T hese BOAT TRAILER PLANS cover the latest in axles, wheels, hubs, brakes, suspension systems, tires, couplers, welded steel frame details, hull support systems, jackstands, and more! All parts and materials specified are standard items readily available anywhere. If you can weld or know someone who can, you can save big bucks. Best of all, you�ll get an all-welded steel framed boat trailer EXACTLY the way you want it to suit your boat EXACTLY! Plans are also suitable to existing boats if you know its size and weight. NOTE: Trailer plans assume the national legal trailering width of 8'6". here

O ur BOAT TRAILER PLANS feature the most modern, up-to-date, and technologically advanced features available to give you a boat trailer that�s equal or superior to those you can buy. Created by designer, Ken Hankinson, long associated with TRAILERBOATS Magazine as columnist and contributing editor, he knows boats AND boat trailers inside out. Each plan includes a comprehensive ILLUSTRATED MANUAL detailing all aspects of the project for QUICK & EASY assembly by anyone who can weld steel. more

Here is my fairing “sander” it’s about 650mm long- Also pictured is a set of dividers I made to measure the distances between screws when putting on the ply

[sujanacast]

I then built a full size cardboard mock- up to see what it would look like and to get a feel for the dimensions

I spent a lot of time getting this true/ symmetrical etc and carefully marking the timber so I could clue and screw it accurately. But first I had to match the cut outs in the centre rib to the curves of the chines and inwales- In the close up picture you can see the G Clamp holding a small steel bracket clamped to the chine for this
