The Smoker Craft 1900 Sunship OB Fish 2005 vs Smoker Craft Alaskan 12 TLS 2007 comparison sits squarely in the category of decisions where specs alone won't tell the whole story — intended use, storage, and long-term ownership costs all factor in.
On paper these two are close siblings in the size department — Smoker Craft 1900 Sunship OB Fish 2005 at 18,0 ft versus Smoker Craft Alaskan 12 TLS 2007 at 18,0 ft. Weight tells a clearer story for trailering families: the Smoker Craft Alaskan 12 TLS 2007 tips the scales at 1 763 lbs — 1 591 lbs less than the Smoker Craft 1900 Sunship OB Fish 2005 at 172 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.
Both boats share a closely matched power ceiling — 180 hp for the Smoker Craft 1900 Sunship OB Fish 2005 and 175 hp for the Smoker Craft Alaskan 12 TLS 2007. Real-world performance will come down more to which motor is actually bolted on, its load at the time, and whether it's a 4-stroke or 2-stroke setup. Fuel capacity breaks the other way: the Smoker Craft Alaskan 12 TLS 2007 carries 37 gallons versus 3 gallons in the Smoker Craft 1900 Sunship OB Fish 2005. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.
For family outings this is probably the sharpest distinction between the two. The Smoker Craft Alaskan 12 TLS 2007 is rated for 6 passengers, while the Smoker Craft 1900 Sunship OB Fish 2005 caps at 1. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Smoker Craft Alaskan 12 TLS 2007 could be the deciding factor.
At this size, power-to-weight ratio matters more than outright horsepower. The Smoker Craft 1900 Sunship OB Fish 2005 comes in at 1 lbs per hp versus 10 lbs per hp for the Smoker Craft Alaskan 12 TLS 2007. The lower the ratio the more explosive the acceleration — meaningful on a short RIB where bursts of speed, quick planing, and agility in surf or tight waterways define the experience.
Bottom line: Choose the Smoker Craft Alaskan 12 TLS 2007 if your priority is putting more people on the water — it handles 6 passengers and at 18,0 ft it has the deck room to back that rating up comfortably. The Smoker Craft 1900 Sunship OB Fish 2005 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 1 that costs less to run day-to-day.
