When two boats share the same hull type — in this case both the Landau 20 Fish 2008 and the Landau 2400 Signature 2008 are pontoon designs with fiberglass construction — the buying decision usually comes down to a handful of practical questions: how many people are you putting on the water, how far do you trailer, and what does your tow vehicle weigh?

Size is the most obvious dividing line here. The Landau 2400 Signature 2008 measures 24,0 feet overall (2008), giving it roughly 22,0 additional feet of deck space compared to the Landau 20 Fish 2008 at 2,0 feet (2008). Weight tells a clearer story for trailering families: the Landau 2400 Signature 2008 tips the scales at 2 301 lbs — 869 lbs less than the Landau 20 Fish 2008 at 1 432 lbs. That difference is meaningful if you're working within a half-ton or three-quarter-ton truck's tow rating, especially once you factor in a motor, gear, and fuel.

The power gap is worth calling out. Rated to 130 hp, the Landau 2400 Signature 2008 has a 40-hp advantage over the Landau 20 Fish 2008's 90-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load.

For family outings this is probably the sharpest distinction between the two. The Landau 2400 Signature 2008 is rated for 12 passengers, while the Landau 20 Fish 2008 caps at 8. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Landau 2400 Signature 2008 could be the deciding factor.

One place where both boats are genuinely identical is tube construction: both run 2 aluminum tubes at 21" diameter. That shared spec means stability and buoyancy characteristics are closely matched — the ride difference you'll feel between them comes primarily from deck length, weight distribution, and motor choice.
