Have you seen this review of my new Zodiac 360 Acti-V Fastroller?
Zodiac Fastroller 360 Acti-V mini-review
I think this model is a very close comparison to the LSI 365 Achilles.
The Achilles is 4" longer but with 3" less beam, and it weighs 18lbs more. Internally the Achilles is 1" longer but 2" narrower.
Both are PVC boats with quality material (both 5yr warranty) but Achilles has some sort of extra Hypalon layer on the air floor for durability (I always use a fitted mat on my air floors anyway).
I like the Achilles red stripe on grey material better than my white/grey Zodiac.
I also like the Achilles having two lift handles near the bow, the Zodiac only has them at the stern and it's a nuisance. Does the Achillies have the dual seat posn of the Zodiac, that's useful.
The Zodiac has its "bow locker", bit of a gimic but it does safely store my basic tools etc.
The Achilles has a 1700lbs load capacity, just 47lbs over the Zodiac. The Achilles is advised at a 15hp motor like the Zodiac but unlike the Zodiac will take a 25hp if you must.
I prefer the fuel tank pad/restraint posn on the Achilles being near the stern compared with the Zodiac centrally towards the bow. Achilles carry their grab rope/strap further forward as well, the Zodiac one stops a bit short for those in the bow.
So it seems if the Achilles was available here I'd probably have given them serious consideration if the price was comparable to or cheaper than the Zodiac.
Edit: I've just looked up a USA dealer to see the Achilles LSI 365 is $1380 more than the Zodiac 360 Acti-V... that's a pretty big difference and I couldn't justify it even for the small advantages I've noticed when it's basically the same size/performance boat.
Hope that helps??
