When two boats share the same hull type — in this case both the Lowe R1860SC 2011 and the Lowe ST170 2009 are modified vee designs with aluminum 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?

On paper these two are close siblings in the size department — Lowe R1860SC 2011 at 18,4 ft versus Lowe ST170 2009 at 17,0 ft. At 956 lbs and 995 lbs respectively, both sit in a similar weight class — either should pair comfortably with most mid-size SUVs and half-ton trucks, though always confirm your specific tow rating with the motor added.

Both boats share a closely matched power ceiling — 90 hp for the Lowe R1860SC 2011 and 75 hp for the Lowe ST170 2009. 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. Both carry nearly identical fuel loads — 2 gal and 2 gal — so range won't be a tiebreaker here.

For family outings this is probably the sharpest distinction between the two. The Lowe R1860SC 2011 is rated for 7 passengers, while the Lowe ST170 2009 caps at 4. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Lowe R1860SC 2011 could be the deciding factor.
