This semi-custom cover is specifically designed to fit a Jon Boat with an outboard engine which is from 15 ft0" to 16 ft0" with a beam of 75". It features Gore Tenara threaded seams and a 5-year warranty. This cover is black (BK) and constructed using Taylor Made's Hot Shot brand fabric. Taylor offers four kinds of fabric in their semi-custom covers: Taylor boat covers come in three levels of customization: Universal, Semi-Custom and Custom. The semi-custom covers are designed for trailering over 30 different hull shapes, from paddle boats to competition ski boats. There are many differences between each variety of cover in regards to what dimensions or accessories they will accommodate. Universally, though, they feature sewn in tie-down loops, a double-folded hem with an integrated shock-cord and 4-ply seams. These boat covers feature Gore Tenara thread in their seams which will not stain, mold, mildew or discolor -- it will outlast the material it is sewn into. Please note that these covers generally aren't made to fit aftermarket swim platforms. Also, please note that this cover comes with a motor hood. Taylor offers a fit guide for their own products that is linked here.
