BOLTROPE ATTACHMENT OF FLEXIBLE HULL PORTION TO RIGID HULL PORTION OF RIGID INFLATABLE BOATS. ABSTRACT OF THE DISCLOSURE A rigid inflatable boat (RIB) has a rigid hull portion and a flexible hull portion with a connection between them. The connection is provided by a boltrope, or the like, received in a grooved anchor. The flexible hull portion includes an enclosure, preferably of a conforming fabric, with a number of inflatable bladders enclosed by the fabric. The boltrope is preferably attached to the fabric of the enclosure by textile tape and stitching. The enclosure fabric is impregnated with a finishing material, such as a resin, while in the position it will be in when containing inflated bladders, and is cured in that configuration A transom is pivotally mounted to the rigid hull portion, and braces hold the transom in an upright position during use. The sides of the transom are scalloped to receive and position the flexible hull portion, and a significant amount of the flexible hull portion extends aft of the transom. A centrally disposed boltrope and grooved lugs may provide a rub strake for the flexible hull portion, and a boltrope at the top of the flexible hull portion may mount accessory components such as cleats, oarlocks, and thwarts. The conforming fabric may be tubular knit fabric spirally wrapped with a second fabric, flat (e.g. warp) knit fabric, non-woven fabric, triaxially woven fabric, or the like.
