MA754AM 4-Channel Amplifier - 75W The marine A754 4-channel amplifier delivers a powerful 75-watt RMS to each of the front and rear speakers in a boat. You can also bridge the amp to 2-channel mode to drive a couple of subs with a 200-watt RMS or 3-channel mode to drive both a pair of full-range speakers and a subwoofer. Speaker-level inputs allow this amplifier to integrate into almost any system, even one using a marine factory radio. Separate high-pass and low-pass crossovers on the front and rear channels allow users to dial in the perfect roll-off to best suit speaker placement and cabin acoustics.

Series 40 Ball Bearing Orbit Block - Single - Becket - Cleat - Swivel Head Features: Ultra Lightweight Low friction 2-stage Orbital ball bearing system Highest working load in its class Low profile and compact High performance cleating Lightweight Kilogram for kilogram of working load, BB and RT Orbit Blocks™ are the world’s lightest. The unique orbital design allows the bearing to only be in the active areas of the floating sheave. This minimizes the mass of the inactive return race and hub. Weight and bulk are further reduced in the different block configurations. The ball bearing single and becket block has a through-sheave becket arrangement. The result? The lowest weight possible. Multi-sheave blocks have only single intermediate cheeks and an ultra-light and efficient head arrangement. This gives a 30% weight saving advantage over the nearest competitor. Other brands just link together their single blocks. This results in unnecessary double cheeks between each sheave, held together by a heavy steel channel across the top of the block. Highest Working Load In It's Class The orbital ball-bearing arrangement gives the largest possible bearing race diameter. This maximizes load performance. The proven Ronstan 2-stage bearing system features high compression grade acetal ball bearings and a secondary full-contact bearing. This gives minimum friction across the full working load range. The floating sheave and bearing system is supported by a fiber-reinforced load frame. The design was computer modeled to be stress optimized. Applications: Mainsheet systems on spinnaker sheet on dinghies to 5m (16ft) Spinnaker sheets on dinghies, sportsboats and small keel boats to 5m (16ft) Halyard, vang and backstay applications on boats to 8m (26ft) Control line applications on larger yachts Materials: Ball Bearings - High compression strength carbon black Acetal.

Series 45 Stand-Up Core Block - Swiveling Core Blocks™ are a true all round solution. A tuned 2-stage bearing system provides excellent performance across the full working load range with an integrated thrust bearing feature and the resilience to handle high dynamic or static loads. Acetal sheave, alloy cheeks and stainless fixings complete the durable package. For reliability and a long service life, these blocks are the right choice for sheets, halyards and control line applications for cruising and racing. Universal Bearing Dynamic and high static load performance The Ronstan Universal Bearing incorporates our proven 2-stage bearing system Stage 1 - Under moderate loads, Acetal ball bearings ensure minimum friction Stage 2 - Under heavy loads, where deformation of ball bearings alone would result in increased friction, a sliding Acetal bearing on a polished stainless steel race takes over, maintaining low friction performance Additionally the ball bearings are configured to act as a thrust bearing between the sheave and cheeks, preventing the sheave from rubbing on the cheeks and causing friction when the line lead in and out of the block isn’t perfect. Particularly important for cheek blocks Alloy Cheek Plates Block cheeks are manufactured from the highest quality alloy for maximum strength. Material optimization and the cut-away design minimizes weight and allows easy fresh water rinsing of salt and debris from the bearings.  Cheek design has been further styled with flaring at the block throat and reduced gap between the cheek and sheave, minimizing rope wear.
