The Deep Impact 36 Cuddy 2017 vs Deep Impact 399 Cabin 2019 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.
The power gap is worth calling out. Rated to 400 hp, the Deep Impact 399 Cabin 2019 has a 50-hp advantage over the Deep Impact 36 Cuddy 2017's 350-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 Deep Impact 399 Cabin 2019 is rated for 12 passengers, while the Deep Impact 36 Cuddy 2017 caps at 10. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Deep Impact 399 Cabin 2019 could be the deciding factor.
Bottom line: Choose the Deep Impact 399 Cabin 2019 if your priority is putting more people on the water — it handles 12 passengers and at 40,0 ft it has the deck room to back that rating up comfortably. The Deep Impact 36 Cuddy 2017 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 10 that costs less to run day-to-day.
