Abstract: A connecting rod for an internal combustion engine with an eccentrical element adjustment arrangement for adjusting an effective connecting rod length, the eccentrical element adjustment arrangement including at least one ball joint including a ball head that is arranged at a support rod and supported in a ball head receiver of a piston, wherein the ball head is secured at its outer surface in the ball head receiver by safety devices against sliding out of the ball head receiver, and wherein the safety devices are configured as a one-piece or a multi-piece annular safety element which is arranged in the piston at least partially bonded or form locking.

Abstract: An elevated tow device comprised of: first and second substantially vertical support members, each slidably and pivotally engaging a boat support structure on a lower end and forming an apex on an upper end, the height and width of which can be adjusted; a tether attachment point at the apex adapted to mechanically engage a tether for connecting to a towed object; at least one forestay connecting the device to a bow of the boat; and at least one rear stay connecting the device to the boat support structure, the forestay and rear stay providing stability to the device. Because of the way that the device is connected to the boat support structure, the device is adjustable in height and width and is also collapsible.
