5 of 5 Fun boat and great for towing August 2, 2022
Reviewer: ben kolpa from Lake Washington  
I use this boat as a part time recreational boat running around the lake and fishing but I also use it as a tow boat to get other broken boats home and as a mobile service platform. Works great in both applications and rides much better with the rigid aluminum hull. I am seeing around 38 mph@ 5500 rpm (I lift because it is getting unstable at the top end). This speed is 1 person(250lbs) with 6 gallons of gas. This is with the  fun prop (15 pitch ss prop). But, with the tow prop ,a 4 blade with a 12 pitch it tows 30 foot boats quite well and is able to plane out with 1700 lbs of load (6 guys) including motor. Great all around boat and fulfills my purposes quite well.

Only Issue that I see is the lack of fuel line routing besides having to use the oar holders but it is not too big of a deal.

Reviewer: Duke Straker from Panama City Florida  
Ordered this boat mew, hand built from the factory; dropped shipped to my front door; The customer service from the crew at Inmar Marine was excellent! After short motor break in period, ran this boat through -(The Gamut), ) on a two week bender; Saint Andrews bay inlet Florida, Lower New River Virginia, then Circled Kellys Island,  to Put In Bay Lake Erie. The Boat Dominated on every occasion and handled excellent, Had the boat airborne on several occasions with a 275lb crewmate in the front. The Boat (Flew Like a Feather, and Stung like a Bee!!) Love this boat, its in my blood, (Thanks Inmar Marine!!)

5 of 5 Great boat. EXCELLENT QUALITY March 15, 2016
Reviewer: Harry G from San Diego  
I purchased this boat 2 years ago and I have been using it primarily for a surfing shuttle.  I've also taken it to Tahoe and Colorado river.  With two dogs and equipment it has seen fair non comercial  use/abuse.  Considering the above the boat looks brand new.  There are no corrosion spots, no tares, unglued seams or flaking of the bottom paint.  I highly recommend this product.
