Boat Hull Types: A Comparison Guide to Mod V, Deep V, and Flat Bottom Jon Boat Designs

Introduction

Buying a boat is the start of a lifelong journey filled with early mornings, casts into the mist, and the kind of family memories that simply can't be made on dry land. Whether you are a high school angler gearing up for your first tournament, a parent looking to take the kids fishing on weekends, or a retiree ready to explore new waters, choosing the right vessel is the first step toward those experiences.

At TRACKER Boats, we aim to make getting on the water more accessible, and the boat you choose should be built with the durability to last for generations. However, if you're new to boating, navigating different boat types—specifically boat hull designs and their purposes—can sometimes feel like learning a new language. Understanding the difference between a Mod V, a Deep V, and a flat bottom jon boat is essential to ensuring you get the performance and stability that matches your fishing or boating lifestyle.

This guide breaks down the basics of aluminum hull designs to help you decide which craft is the perfect fit for your future adventures.

Before diving into specific boat types, it is helpful to understand what a hull actually does. The hull is the watertight body of the boat that rides in the water. Its shape determines how the boat handles waves, how stable it feels when you are standing up to cast, how shallow of water you can access, and how fast it can go.

For aluminum fishing boats, the design of the hull is a balance of physics and craftsmanship. The goal is to create a vessel that is tough enough to handle underwater hazards like stumps or rocks, yet light enough to be fuel-efficient and easy to tow.

One of the most critical concepts to understand is "deadrise." Deadrise is the angle of the hull bottom relative to a horizontal line. A completely flat boat has zero deadrise. A boat with a sharp "V" shape has a high degree of deadrise. Generally speaking, a sharper V cuts through waves better (softer ride) but may rock more when stopped. A flatter bottom is more stable when stopped but can be rougher in choppy water.

The engineering magic happens when boat designers mix these elements to create specialized performance for different types of water.

Mod V Hulls: The Bass Fishing Specialist

If you have watched professional bass fishing tournaments or seen sleek aluminum boats zipping across a lake, you have likely witnessed the Modified V (Mod V) hull in action. This is one of the most popular boat types for anglers who prioritize speed, casting stability, and access to a wide variety of fishing spots.

What is a Mod V?

A Mod V hull is a hybrid design. It typically features a sharper V at the bow (front) to cut through the water, which transitions to a flatter bottom toward the transom (back). This design offers the "best of both worlds" for many anglers with the cutting ability of a V-hull and the shallow-water capabilities and stability of a flat bottom.

The TRACKER REVOLUTION™

TRACKER Boats take the standard Mod V concept and engineer it for superior performance. Our TRACKER® PRO TEAM™ bass boat series rides on our exclusive variable deadrise REVOLUTION™ hull.

Standard aluminum boats might use a simple, single-angle design, but the REVOLUTION™ hull is precision-engineered. It features a 16° angle at the bow which allows the boat to knife through the waves effectively, reducing the slap and bounce often associated with lighter aluminum boats. This angle transitions smoothly along the length of the boat to a flatter 10° angle at the transom.

This 10° angle at the transom is crucial. It provides exceptional stability at rest. When you shut off the engine and stand up on the casting deck to flip a jig or land a fish, the boat feels solid and planted. This is vital for families fishing with children or competitive anglers who need a stable platform to work from.

Performance and Speed

TRACKER Power-Trac Set-back transom

Another key feature of our Mod V design is the POWER-TRAC™ set-back transom. This design element delivers undisturbed water to the prop. By ensuring the propeller is biting into "clean" water, we achieve optimized performance both on take-off (hole shot) and at top-end speed.

Speaking of speed, TRACKER® PRO TEAM™ Mod Vs riding on the REVOLUTION™ Hull are rated for outboard motors ranging from 9.9 to 150 HP, depending on the model. On average, a PRO TEAM model equipped with the highest-rated motor for its size will see top speeds around 40 mph. For those craving more adrenaline or needing to beat competitors to a honey hole, the PRO TEAM 195 TXW is able to reach estimated speeds up to 60 mph.

Because of the confidence we have in this engineering, we offer the SMOOTH RIDE GUARANTEE™ on these models. It is a promise that your aluminum boat will ride comfortably, defying the old myths that aluminum boats have to be rough or noisy.

Mod V Hulls are Best For:

  • Bass and panfish fishing.
  • Lakes and rivers with light to moderate chop.
  • Anglers who want a blend of speed and stability.
  • Those fishing in shallow cover (docks, stumps, vegetation).

Deep V Hulls: Conquer Big Water & Multi-Species Fishing

When the wind picks up and the whitecaps start rolling across big water, the Deep V hull becomes the undisputed champion. These boats are designed for "multi-species" fishing—walleye, pike, muskie, and trout—often in larger, more unpredictable bodies of water.

What is a Deep V?

As the name implies, a Deep V boat has a much steeper deadrise (V-shape) that runs the entire length of the boat, or at least significantly further back than a Mod V. The hull sits deeper in the water, and the sides (gunnels) are usually higher. This design is built to slice through large waves rather than riding over the top of them, providing a much softer ride in rough conditions.

Hulls Engineered for a Drier Ride

One of the biggest concerns for anglers on big water is staying dry. If a hull hits a wave incorrectly, it can send a sheet of spray right into the cockpit. TRACKER® Deep V boat hulls address this with specific engineering features called reverse chines.

Chines are the changes in angle on the hull's surface. On our Deep V models, the reverse chines are turned-down edges where the transom's sides join the hull. The opposing angle of these chines forces the water spray downward and away from the boat, rather than allowing it to curl up and blow back onto the passengers. This results in a significantly drier ride, keeping you and your family comfortable even when the weather turns.

Stability and Control in Rough Water

While Deep V boats are known for cutting waves, some anglers worry they might rock too much when trolling or drifting. TRACKER solves this with the same reverse chine technology.

Those turned-down edges do more than deflect spray; they also improve responsiveness and stability. They "bite" into the water, providing edge-to-edge stability. When you are trolling crankbaits along a ridgeline or netting a trophy walleye over the side, that extra bite keeps the boat level and predictable. The hull also features lifting strakes, which help lift the boat onto the water's surface quickly for better acceleration and fuel economy.

Deep V Hulls are Best For:

  • Walleye, Pike, and Muskie fishing.
  • Big lakes and open water where conditions can change quickly.
  • Families who want higher sides (freeboard) for added safety with small children.
  • Anglers who extend their season into early spring or late fall when staying dry is critical.

Flat Bottom Jon Boats: Duck Hunting & Utility Workhorses

Sometimes, the best spots on the water are those that are hardest to reach. Shallow backwaters, narrow rivers, and stump-filled swamps are the domain of the flat bottom Jon boat. These are the workhorses of the water—simple, rugged, and incredibly versatile.

Duck Boat

Practical & Rugged Design Philosophy

A flat bottom boat typically has little to no deadrise. The bottom is practically flat from side to side (0°-7°) for the entire length of the boat. The deadrise will not gradually change from bow to stern as it does on Mod V designs. This design offers two distinct advantages:

  1. Shallow Draft: Because the boat doesn't sit deep in the water, it can float in mere inches of depth. This allows you to run in flooded marshes and timber, or navigate weed-choked creeks that would ground a Deep V or Mod V boat.
  2. Initial Stability: On calm water, a flat bottom boat is incredibly stable. It resists tipping from side to side, making it an excellent platform for duck hunting and shooting , or for standing to cast a rod or bowfishing.

Durability & Value

For the budget-conscious angler or the outdoorsman who values utility above all else, the Jon boat is often the entry point into boat ownership. TRACKER Jon boats are built with the same commitment to quality as our high-performance models. They are often lighter, making them easier to tow with smaller vehicles or even load into the bed of a pickup truck.

While they may not offer the wave-slicing capability of a Deep V or the top-end speed of a Mod V bass boat, their flat hull design makes them the most efficient load-carriers. They provide maximum interior space and buoyancy for their size, which is why they are favored not just for fishing, but for hunting and utility work as well.

Flat Bottom Boat Hulls are best for:

  • Duck hunting and bowfishing.
  • Small lakes, ponds, marshes and calm rivers.
  • Getting into extremely shallow water.
  • First-time boat owners looking for high value.

Choose Your Best Boat Type

Choosing between the basic hull types like a Mod V, Deep V, or Jon boat with practically no V, ultimately comes down to where you spend your time on the water, what type of water conditions you expect, and what you will be doing while you're out there.

  • Choose the Mod V if you are a bass angler or a family that wants a sporty, fast ride with a stable platform for casting near the shoreline. The 40-60 mph top-end potential and Smooth Ride Guarantee ensure excitement and comfort.
  • Choose the Deep V if your adventures take you to big water where safety, depth, and a dry ride are paramount. The reverse chines will keep you stable and comfortable when the wind picks up.
  • Choose the Jon Boat if you need rugged simplicity to access the shallowest, wildest places where other boats simply cannot go.
