Outboard Engine Information

What size of HP?

Thanks to their light weight and exceptional lift, inflatable boats plane with lower power outboards. To determine the correct motor HP size for your boat, follow the recommended power output:

NEVER USE A MOTOR POWER HP HIGHER THAN INDICATED ON THE MANUFACTURER’S I.D. PLATE AS THIS COULD RESULT IN LOSS OF CONTROL

  • Over-powered and your boat can be difficult to control. Under no circumstances should you fit an outboard which exceeds the maximum permitted engine power: you may be breaking the law.
  • Under-powered and you may not have that margin of security necessary to go upwind or against the currents.
  • For quiet activities you do not need a very powerful engine: 8 hp is sufficient for a 4.20m/13’9″ boat.
  • For sportier activities such as water skiing or diving you will need at least 30 hp.
  • With smaller outboards, go for tiller control, giving direct control over the boat and allowing for quick maneuvering.
  • Above 25 hp, for greater comfort and safety, we recommend that you choose a steering console.

It is recommended that you choose a motor suitable for your principal boating activities. The recommended and maximum powers are given in the technical specifications.

 

The weight of the outboard

The weight of the outboard has a direct effect on the handling of your inflatable boat.

  • For the same power output, choose the lighter outboard
  • Check that the engine’s weight is compatible with the maximum recommended weight for your boat.

 

Shaft length of the motor (short, long or extra-long)

  • Each model has been designed to accept one length, not all.

Propeller

  • Your motor may come equipped with a “standard” propeller. Ask your dealer to assist you in choosing the optimum propeller for your principal use.

 

Installing the motor

  • Install the motor along the centerline of the inflatable boat, in the middle of the tightening plate (1) (see diagram)
  • Fully tighten the brackets (2) by hand and check that they are still properly tightened after 15 minutes of running.
  • Secure the motor to the loop (4) on the motor tightening plate (1) with a safety cable (3).

 

Adjusting the tilt of the motor

To get the best performance and maneuverability, you may have to adjust the tilt (the angle of the motor to the transom) more often in relation to navigation conditions.

In a calm sea, the motor must be positioned so that the axis of the propeller is parallel to the water. But an adjustment of the tilt is recommended under certain other conditions:

The adjustment can be manual or by an electric trim, if supplied with the engine. The trim is a hydraulic control that inclines the motor in navigation.

Usually:

  • If the motor is positively trimmed, the boat will porpoise.
  • If the boat is negatively trimmed, the boat will nose down.

 

 

 

When to use the positive trim:

  • In a following sea: load the stern and if necessary set the tilt pin in the 3rd or 4th hole position (manual trim)
  • When you want to increase speed (electric trim)

 

When to use the negative trim:

  • With a head on sea and wind: load the bow and if necessary set the tilt pin in the 1st or 2nd hole position (manual trim)
  • When planing to minimize the porpoiseing (electric trim)

 

NEVER USE A MOTOR POWER HP HIGHER THAN INDICATED ON THE MANUFACTURER’S I.D. PLATE AS THIS COULD RESULT IN LOSS OF CONTROL.

Security aspects of an inflatable boat

Security, stability, buoyancy, unsinkabililty. Compared to traditional boats, an inflatable boat offers some important advantages: it is safer, lighter, more practical and more economical.

Reassuring stability
The stability of an inflatable boat, thanks to its large buoyancy tubes and resulting low center of gravity, is such that under normal circumstances it is practically impossible to capsize. This quality, which is essential to safe confident navigating, is especially appreciated by divers and fisherman.

Exceptional load capacity
Inflatable boats are capable of carrying more or maneuvering, without taking on water. This is because the buoyancy of an inflatable boat is far greater than that of a traditional boat giving it a higher loading capacity.

Security, buoyancy, unsinkabililty
The buoyancy tubes of an inflatable boats include several compartments sealed one from the other by conical bulkheads. Because of its large air reserve, the boat will stay stable and unsinkable, even with one of the independent air chambers deflated.

The practicality of owning an inflatable

Inflatable boats are easy to store and almost as light as air. Light, easy to put into the water or be pulled on the beach, an inflatable is operational in a wink and offers a variety of navigational possibilities.

Easy to store
Once deflated and folded the space taken up by an inflatable boat is so compact that transporting it and storing it becomes extremely easy. Have you ever tried shutting the car trunk on a traditional boat? Can you store a traditional boat in a closet or the corner of the garage? Packed away, an inflatable boat goes wherever you want to go.

Almost as light as air
Take a look at an inflatable boat. You see the fabric, a wooden transom, the fittings…..but you forget the air contained in the inflatable keel or in the buoyancy tubes which gives the boat its shape. Looked at this way, it is hardly surprising that a fully inflatable can be up to 3 times lighter than a comparable traditional boat.

What size boat? How heavy?
Inflatable boats come in a range that offers a variety of models adaptable to the most diverse needs. Before choosing an inflatable it is important that you ask yourself the following questions: What size? What weight?

The size
Size determines space on board and carrying capacity. It also directly influences the level of performance: a larger boat is more stable, more comfortable and easier to get planing.

The weight
Below 30 Kg/66 lbs, your inflatable is a feather weight: a primary feature for a tender.  Between 30 Kg/66 lbs and 100 Kg/220 lbs, 2 to 3 people can comfortable carry it by hand.  100 Kg/220 lbs to 150 Kg/330 lbs and a trolley or launching wheels become necessary. Over 150 Kg/330 lbs, a trailer is required. However lighter than a similar rigid traditional boat, towing and launching present few problems.

Inflatable boat fabrics

posted by The Captain @ 1:39 PM
Friday, May 25, 2012

A major component of an inflatable boat is obviously the fabric. Inflatable boat fabric technology has evolved greatly over the last 20 to 30 years, and now includes plastomers, polyurethanes and other fabrics, which can sometimes be stronger, lighter, thinner and less expensive to assemble than the original rubber fabrics. Of course it costs a great deal of money to develop new fabrics or even to switch manufacturing processes to use them. Many manufacturers, big and small, don’t have the will or the resources to do this, and that’s why they generally hide that fact by resorting to condemning new technological advances in fabrics.

For instance, Zodiac’s fabrics have always been on the leading edge of technology and their willingness to research and experiment has led to some innovative new fabrics. These new fabrics are developed to be the best for their intended use. Fabrics used for a small tender don’t need to be the same as those for a large RIB, because the intended use is not the same. Some manufacturers do not have the means or know-how to employ different fabrics, so they just use one. In these cases the consumer, may end up paying too much or getting too little.

Most fabrics consist of a strong, close-weave mesh of polyester or nylon material which is sandwiched between 2 coatings to provide extreme flexibility, superior air and water tightness, as well as resistance to abrasion and the sun’s UV rays. Zodiac uses a polyurethane fabric called “Strongan” and assembles their inflatable boats by thermobonding the fabric.

Heavy Duty Fabrics
Some inflatable boats are still made from a rubber-based fabric called Hypalon. While this is still a very good material, its major downfall is that it can only be joined by gluing, done manually. Problems including poor bonds, delamination of seams or fabric can still affect these glued fabrics. Today, many inflatables are manufactured from polyurethane fabrics, although larger inflatables (particularly RIBs used for rescue or military purposes) use hypalon because thicker hypalon fabrics are still considered to be stronger and more durable than polyurethane. There are some hypalon fabrics that are “2-ply” or a double unit made up of hypalon/weave/hypalon/weave/hypalon and are used for extreme situations including bumper padding, bow skirts, anti-chafe patches and similar applications.

Seams
Apart from its superior toughness and durability, Zodiac’s Strongan fabric allows the use of Zodiac’s computerized machine-welding process known as “thermobonding”, the welding of fabric using hot air. Two sealing strips are thermally bonded to the butted fabric seams in a continuous electrothermal process. A highly airtight seal is created when the narrow inner strip literally melts into the collar material. The wider exterior strip functions as a overlapping structural connection and a sealer against water penetration. Thermobonding creates seams that are typically stronger than the fabric itself and produces a better seam than any hand-gluing method.
