Aqua Marina 11’0″ AIRCAT Inflatable Catamaran. 3.35m with DWF Air Deck
Great boat but trouble with support

I took the boat out. Everything worked perfectly EXCEPT I somehow lost one of the capscrews to hold an oar in the swivel assembly. So far I have found the part number and a Japanese company that can sell me the part for some number of yen. Then I found somebody in Canada and there would be shipping charges. There is allegedly USA distributers but so far I am unable to find one. So my 5 star rating is subject to drop if I find it's going to be very expensive and difficult to replace a part I believe should cost no more than a few dollars. I would have looked harder for it if I had known. 😃

Simrad NSS12 evo3S Combo Multi-Function Chartplotter/Fishfinder - No HDMI Video Outport - 000-15403-002
All-in-One Info Center

Hooked up my mercrusier engine to the Simrad and it's like having a boat dashboard on steroids. The ecogps function's a lifesaver, helps me get the best trim and rpm for max mileage. Love that I can see my fuel range on the chart and track fuel usage trip by trip. Customizable screens and side bars are a plus. If you can't find the info on this, you probably don't need it. And shoutout to their support team - the guy I talked to knew his stuff and helped me out! When I ordered, it came 2 days later! No waiting around. Great buy!
