When two boats share the same hull type — in this case both the Maritime 1690 2012 and the Maritime 18-D 2008 are modified vee designs with composite 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 — Maritime 1690 2012 at 16,5 ft versus Maritime 18-D 2008 at 18,0 ft. At 12 lbs and 16 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.
The Maritime 1690 2012 carries a rated maximum of 75 hp. Engine data for the Maritime 18-D 2008 wasn't available in our records — check the manufacturer's spec sheet before sizing a motor.Both carry nearly identical fuel loads — 26 gal and 29 gal — so range won't be a tiebreaker here.
For family outings this is probably the sharpest distinction between the two. The Maritime 18-D 2008 is rated for 7 passengers, while the Maritime 1690 2012 caps at 6. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Maritime 18-D 2008 could be the deciding factor.
The Maritime 1690 2012 has a documented top speed of 32 mph. Speed data wasn't available for the other model.
Bottom line: Choose the Maritime 18-D 2008 if your priority is putting more people on the water — it handles 7 passengers and at 18,0 ft it has the deck room to back that rating up comfortably. The Maritime 1690 2012 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 6 that costs less to run day-to-day.
