There is a reason the ALumicraft is cheaper. Between my kid’s john boat and a welded alumicraft he bought for his 40 HPMerc, and a Lake city guide with an Alumincraft the experiences could not have been worse. Both riveted boats eventually leaked, and the welds cracked year one on the new John Boat. The new Navigator is great looking and has some nice accesories, but I ended up wih a choice between Lund and Cresliner, and bought the latter.
