Boat Collar Design

2019 Good Design Awards gold winner.

THE DETAILS BEHIND THE INVENTION

INITIAL OBJECTIVES

01
Change shape of hulls to improve their performance
02
Stabiliser that works whilst at-speed, not only during rest
03
Flotation to keep swamped boats balanced and upright
04
Never to cause drag but, rather, to generate lift and speed

AN ECOSYSTEM OF DESIGN ELEMENTS

EVERY FEATURE EFFECTS ANOTHER FEATURE'S EFFECTIVENESS

SHAPE

Cut on a specific 10 degree angle to create a wide reverse chine when fitted. Using hydro dynamic principles, water and spray is then captured for lift & speed.

SIZE

Fitted full-length, to the bow, so water pressure can lift the bow out of nose-diving, broaching and capsizing dangers.

MATERIAL

Criteria: #1. Provide superior flotation. #2. Be durable for fishing. #3. Survive a marine environment. #4. Twist with the shape of boats. #5. Be easy to install.

POSITION

Installed low on the side to #1. create a reverse chine, for performance. #2. increase a boat's footprint in the water, for maximum stability.

MAIN PERFORMANCE BENEFITS

HOW THE DESIGN WORKS ON YOUR BOAT

It may look like just a length of grey foam, but meticulous detail has gone into its design for optimal performance benefits and longevity.

STABILITY

External buoyancy, positioned low at the chine, together with the angular reverse-chine shape, 'cups' the water, providing great resistance to tipping. Curved flotation products do not have this force of resistance.

Performance at rest: use every inch of your boat at-will, with your boat responding with rock-solid stability.

Performance underway: travel side-on to swell, crossing waves at an angle, (which is gentler), while your Collar constantly balances your boat.

ANTI BROACHING

The sharp angle of the full-length reverse-chines of a Collar act like fins on a surfboard. Your boat gains lateral grip (won't slide sideways), and can track straight, easily keeping its true course. 

This fin-like control, together with sideways stability and hydrodynamic lift (especially at the bow), keeps your boat stable and resistant to broaching. It will no longer get a mind of it's own and veer wildly off track.

Performance: overtake waves with confidence, knowing you're in control and your boat can handle it.

LEVEL FLOTATION

Boats with "Basic" or no flotation usually capsize &/or sink when flooded. Buoyancy placed around the outside of your hull gives you flotation that continues to balance your boat when flooded. Due to the high volume of buoyancy in Collars, they are extremely hard to submerge, so they keep the sides of your boat steady, counteracting the natural forces to capsize.

Flooded performance:

  1. Gear not tipped out & sunk with a capsize.
  2. Wait inside your balanced boat, for rescue.
  3. Motor ashore.

LIFT & SPEED

The spray you generate at speed gets trapped and pressurised under the inverted V of your new reverse chine. This lifts your boat in a similar way to a hydrofoil, because liquids cannot be compressed.

Performance:

  1. Go faster through choppy conditions, using less throttle, with better fuel economy.
  2. Enjoy the softer ride of hydrofoil-action.
  3. Spray is turned down for your driest ride. 
WHAT MAKES IT ALL POSSIBLE

TUFF-TEC FOAM

The "Tuff-tec" foam we use for Boat Collars is custom-made especially for us, because it meets our specific list of criteria. 

It is a polyethylene foam that has a closed-cell wall structure, in two grades of density: 35kg/m3 (light) and 100kg/m3 (dense).

Tuff-Tec foam for Boat Collars:

  • Petro-chemical resistant (petrol & other solvents won't melt it).
  • UV stabilised, to last longer in the sun.
  • Closed-cell, so it can not absorb liquids.
  • Has a harder, 100kg/m3 (dense) layer within, for stronger fitting & easier installation.
  • Has a harder, 100kg/m3 (dense) layer on the outside, for durability and longevity.
  • Has a 30+ year lifespan.

Points of interest:

  • Can be painted (see Maintenance page for how).
  • Can be fibreglassed over &/or treated with anti-foul.
  • Comes in a "Tinnie Grey" colour as standard.
  • Can be cut/trimmed with your hand-held, wood-panel saw (for DIY).

WHY INVEST IN A BOAT COLLAR?

4m Sniper with Boat Collar
INSURANCE POLICY

Unlike insurance that pays for damages if your boat capsizes or sinks, a Boat Collar prevents such disasters from happening at all.

UNSINKABLE

Protect your boat and your crew as much as possible, by making your boat a steady, unsinkable life-raft.

COMFORT

Save on Chiropractic bills and enjoy a cushion-of-air ride.

WARRANTY

24 month manufacturer's warranty for boats up to 5m/16.5ft.

KEEP YOUR BOAT

Save buying another boat that is bound to have different problems. Just fix the boat you know, so it becomes the most trusted boat ever.

PEACE OF MIND

Truly relax with a boat that is unsinkable and behaves far bigger & better than it is.
