Naish Sprint 7.7 + Infinity Prime SDM 460 Windsurfing Set

Description:

A set based on the Naish Sprint 2024 7.7 sail and the Infinity Prime SDM 460 55% Carbon mast is a complete configuration for windsurfers looking for a combination of an early planing start, good speed and easy handling.

The Sprint 7.7 is a no-cam freeride sail. In its larger sizes it's equipped with 6 battens, giving it greater profile stability, power and speed potential. The construction allows the sail to be used both on large freeride boards and on more sporty freerace boards.

The whole set is completed with an Infinity Prime SDM 460 55% Carbon, an aluminum Infinity Excellent boom, an Infinity SDM 3 Big Rollers 30 cm extension and fixed Dakine Fixed 26" harness lines.

This is a set designed primarily for fast freeride, where what matters is an easy planing start, acceleration and the ability to maintain high speed without needing more demanding slalom equipment.

Who is this set for?

We especially recommend this set for:

• windsurfers at an intermediate and advanced level,

• people looking for a large sail for freeride in lighter and medium wind,

• people riding on large freeride and freerace boards,

• windsurfers who want to plane as early as possible,

• people looking for a lot of power, but without the difficulties typical of cambered sails,

• windsurfers who want to combine good speed with easy handling,

• people who need a larger sail for lakes and waters with uneven wind,

• windsurfers who want to develop fast freeride without moving to a full slalom setup.

What's included in the set?

Sail: Naish Sprint 7.7

The Naish Sprint is a sporty freeride sail without camber, designed with an emphasis on an early planing start, good speed and easy handling. The no-cam construction makes the sail simple to tack and doesn't require complicated adjustment.

The 7.7 m2 size is one of the larger Sprint variants and has 6 battens. This makes the sail profile more stable, which translates into more power, better acceleration and higher speed, especially on larger freeride and freerace boards.

The Sprint was designed to provide a lot of power in the lower wind range, while maintaining a controlled and predictable character. The efficient profile makes it relatively easy to use lighter gusts and quickly accelerate the board.

The construction uses laminated monofilm and X-Ply, and additional seam reinforcements increase durability. Torx batten tensioners allow for precise and repeatable sail setup.

Key advantages:

• a very good planing start,

• a lot of power in the lower wind range,

• 6 battens providing a stable profile,

• good top speed,

• easy and predictable handling,

• no camber,

• fast and simple tacking,

• laminated monofilm,

• X-Ply elements,

• reinforced seams,

• a precise Torx batten tensioning system.

Mast: Infinity Prime SDM 460 55% Carbon

The Infinity Prime SDM 460 55% Carbon is a solid mast designed for recreational freeride. The construction uses 55% carbon, Pre-Preg technology and a standard SDM diameter. The mast is characterized by high stability and resistance to damage, so it works well with regular use.

The SDM fits well with the character of the large Sprint. The larger mast diameter provides stable performance and good power transfer to the sail.

The Infinity Prime uses Constant Curve characteristics, making it a versatile mast designed to work with a wide range of sails.

Key advantages:

• 55% Carbon,

• an SDM construction,

• a length of 460 cm,

• Pre-Preg technology,

• good stiffness,

• high damage resistance,

• Constant Curve characteristics,

• a good compromise between price, durability and performance,

• a 2-year manufacturer's warranty.

Boom: Infinity Excellent 185-245

The Infinity Excellent Series is an aluminum boom designed for windsurfers looking for a good combination of stiffness, durability and comfort.

The construction is made from T8 aluminum, and the tubes have a diameter of 32 mm. EVA foam padding provides a comfortable, confident grip, which is especially important during longer sessions on a larger sail.

The boom has a 60 cm adjustment range, and a double-pin system allows for precise length adjustment. A one-piece end fitting increases construction stiffness, while the Loop-Loop-Go system makes attaching the sail easier.

For the Sprint 7.7, the manufacturer states a boom length of 212 cm, so the 185-245 cm variant provides a very large adjustment margin and allows precise sail setup.

Key advantages:

• T8 aluminum,

• a 32 mm tube diameter,

• soft EVA foam,

• high stiffness,

• a 185-245 cm adjustment range,

• 60 cm of adjustment,

• adjustment every 20 mm,

• a one-piece end fitting,

• double pins,

• the Loop-Loop-Go system,

• a universal head compatible with RDM and SDM.

Extension: Infinity SDM Alu 3 Big Rollers 30 cm

The Infinity SDM Alu 3 Big Rollers is an extension designed for SDM masts, created for sails requiring a lot of force when pulling in the luff.

Its biggest advantage is the use of three large, parallel rollers. Thanks to the mechanical leverage, pulling in the sail requires significantly less force, which is especially useful with larger freerace and race sails.

The extension is made from hardened aluminum, so it maintains high stiffness even at greater extension lengths. It has the Euro Pin system, an adjustment scale every 2.5 cm and an integrated cleat.

Key advantages:

• an SDM construction,

• hardened aluminum,

• 3 large rollers,

• very easy pulling in of the luff,

• a large mechanical leverage ratio,

• adjustment every 2.5 cm,

• the Euro Pin system,

• an integrated cleat,

• high stiffness and durability.

Harness lines: Dakine Fixed 26"

The Dakine Fixed is a simple and durable fixed harness line. The 8-strand, pre-stretched FSE Robline rope used provides durability and limits length change during use. The lines also have a wear-resistant polyurethane coating and non-slip pads that stabilize their position on the boom.

The 26" version provides a versatile length for classic freeride.

The fixed construction is especially convenient for people who, once they've found the right position, want to keep the exact same harness setting during subsequent sessions.

Key advantages:

• a length of 26",

• a fixed construction,

• an 8-strand FSE Robline rope,

• pre-stretching,

• a polyurethane coating,

• non-slip pads,

• a U-shaped opening.

How does this set behave on the water?

The Naish Sprint 7.7 provides a very good planing start and fast acceleration, so it works excellently on larger freeride boards. Six battens stabilize the sail profile and allow you to maintain high speed.

The large surface area gives plenty of power in lighter wind, and the no-cam construction keeps the sail easy to handle and simple to tack.

This is a set focused on fast freeride: a lot of power, good acceleration, high speed and, at the same time, easy control.

Hydrosfera's opinion

The Naish Sprint 7.7 is a very good choice for a windsurfer who wants to make the most of lighter wind, but doesn't want to move to a sail with camber that's harder to handle.

The biggest advantage of this set is its consistency. The Sprint 7.7 is factory-specified to work on an SDM 460 mast, and the Infinity Prime SDM 460 used here matches that configuration. Naish also states a 26 cm extension, so the 30 cm extension used here provides an adequate adjustment range.

A large sail, a stable SDM mast and a stiff Infinity Excellent boom form a set that will work especially well with larger freeride and freerace boards.

This isn't equipment focused solely on comfortable riding. The Sprint 7.7 has a clearly sporty character and lets you develop high speed, but at the same time remains simple to handle thanks to its no-cam construction.

In short: a very versatile large freeride set that works great on the Baltic and on lakes, especially when the priority is an early planing start and making good use of lighter wind.
