New 2005 Tige 22i

2005 Tigé 21i — Full Overview

Overview

The Tigé 21i was built around the idea of creating a versatile, family-friendly inboard that could perform well across several watersports. At 21 feet, it is large enough to comfortably accommodate a group while remaining relatively easy to trailer and maneuver.

Tigé emphasized the 21i's roomy interior, storage, deeper freeboard and ability to transition between skiing and wakeboarding. One of its signature features is the Skybox seating, which allows the rear seating configuration to be changed to better suit passengers and watersports activities.

Key Specifications

The 315-hp gasoline Vortec is the commonly documented factory engine for the 2005 21i. Some listings and databases contain inconsistent horsepower information, so the actual engine and rating should always be verified on the specific boat.

Engine & Performance

The GM 5.7L Vortec is one of the biggest strengths of the 21i from a long-term ownership standpoint. The 315-hp engine provides plenty of power for recreational skiing and wakeboarding while being a relatively straightforward powerplant compared with many newer electronically controlled marine engines.

The direct-drive configuration also keeps the engine relatively centralized in the hull. That contributes to the boat's balanced handling and makes it particularly well suited to traditional watersports.

For buyers looking at a 20-plus-year-old 21i, however, condition is far more important than the original horsepower rating. A well-maintained engine, transmission, cooling system and driveline are worth considerably more than a boat with a lower-hour engine that has been poorly maintained.

ConvexV Hull & TAPS2

One of the defining characteristics of the 21i is Tigé's ConvexV hull design combined with its TAPS2 system.

The TAPS system allows the running attitude of the boat to be adjusted, giving the driver the ability to change the boat's wake and handling characteristics. This was one of Tigé's major differentiators during this era.

For skiing, the boat can be configured toward a flatter wake. For wakeboarding, the hull and TAPS system can be adjusted to create a more pronounced wake. That versatility was a major selling point for the 21i.

Wakeboarding

The 21i makes a very good recreational wakeboard platform, especially considering its age.

The combination of the 21-foot hull, 102-inch beam and TAPS system gives the boat a good foundation for producing a wake that can be adjusted to the rider's preference.

It isn't going to duplicate the enormous, highly shaped wakes produced by a modern 2026–2027 wake boat with several thousand pounds of integrated ballast, but that's not really what the 21i was designed to do.

For casual wakeboarding, family riding and intermediate riders, a properly weighted 21i can still provide an enjoyable wake.

Interestingly, owners have also successfully experimented with adding ballast and wake-shaping devices to older 21i boats for recreational wakesurfing.

Waterskiing

This is an area where the 21i really makes sense.

Unlike many modern wake-focused boats, the 21i was designed to be a multi-sport boat. Its direct-drive layout and adjustable hull make it well suited to recreational slalom skiing, tubing and general watersports.

The boat's ability to flatten out its wake makes it substantially more versatile than a modern wake boat optimized primarily for wakeboarding and wakesurfing.

Interior & Family Use

The 21i's 102-inch beam is particularly impressive for a 21-foot boat. It gives the boat a wide, stable feel and creates useful interior space.

Tigé specifically marketed the 21i as one of the roomier 21-foot direct-drive boats of its era. The deeper freeboard also provides a greater feeling of security for families with children.

The Skybox seating is another clever feature. The rear seating can be configured to allow passengers to face different directions, which is useful when watching riders behind the boat.

For a family looking for an older boat that can handle skiing, wakeboarding, tubing, swimming and cruising, the layout remains practical.

Storage & Practicality

For a 21-foot boat, the 21i offers a respectable amount of storage. The wide hull helps provide usable space throughout the cockpit.

The 36-gallon fuel tank is adequate for a boat of this size, although fuel consumption naturally depends heavily on how the boat is operated and how much ballast is being carried.

At approximately 3,880 pounds dry, the boat is also manageable for trailering compared with many newer 21–23-foot wake boats. Remember that the real towing weight will be considerably higher once you add the trailer, fuel, batteries, gear and accessories.

What I Like About the 2005 21i

1. Excellent versatility
It can handle skiing, wakeboarding, tubing, cruising and family recreation.

2. Proven 5.7L Vortec power
The GM-based 5.7L is a familiar and relatively straightforward marine engine.

3. 102-inch beam
The wide hull gives the boat a surprisingly spacious interior for a 21-footer.

4. TAPS2 adjustability
The ability to adjust the running attitude gives the boat more versatility than many comparable boats of the era.

5. Direct-drive layout
Great for traditional watersports and relatively simple mechanically.

6. Classic Tigé styling
The 21i has the distinctive look of Tigé's early-2000s boats and has developed something of a following among older Tigé owners.

Things to Check on a Used 2005 21i

At this point, the biggest concern isn't that the boat is a 2005 — it's how that particular boat has been maintained.

I'd pay particularly close attention to:

• Engine compression and overall condition
• Cooling system and manifolds/risers
• Transmission operation
• Shaft, strut and propeller
• Rudder and steering system
• Stringers and structural integrity
• Floor condition
• Bilge and ballast pumps
• TAPS2 operation
• Upholstery and vinyl
• Dash gauges
• Electrical components
• Navigation lights and horn
• Trailer condition
• Any signs of water intrusion
• Previous repairs or fiberglass work

The TAPS system should be operated repeatedly during a sea trial to make sure it responds properly.

Older 21i owners have also reported issues with aging instrumentation and speed/depth sensors, which isn't unusual for a boat approaching 21 years old.

Bottom Line

The 2005 Tigé 21i is a very appealing older inboard for someone who wants a genuine watersports boat without spending modern wake-boat money.

Its biggest strengths are its 315-hp 5.7L Vortec, spacious 21-foot/102-inch hull, direct-drive layout, TAPS2 system and multi-sport versatility. It is particularly attractive for someone who values skiing and recreational wakeboarding rather than needing the enormous surf wakes and technology of today's premium wake boats.
