Our priority in Point-7 is to focus on the windsurfing rig and make it a winning rig no matter the discipline. The boom is what we feel with our hands when sailing. It’s what makes us feel the wind in the sail. We develop sails – we have developed the racing sail which has won the PWA Slalom World Title, and a boom is an integrated part of the rig, which brings a winning performance to the rider.

An Aluminum boom does not just need to be a good price, a carbon boom doesn’t just have to feel light and stiff. There is a lot more behind the boom and its features, most importantly: comfort, performance, and safety.

Some booms might look the same, some can be lighter or stiffer than others, but the most the important characteristics is the reflex. It can make a sail feel light or heavy, powerful, or more comfortable. The reflex needs to vary according to sail size and conditions. A 220-racing boom cannot have the same structure of a 140-wave boom. Just like the masts, the synergy between the boom and mast is very important. Just like the sail and the mast. What is sometimes discussed by looking at a product on the beach, might not be bringing the same result once taken to the water and put under pressure.

Development: The first target from the Point-7 Black Team when developing a boom is the curve. This is not about having a curve from the new generation as many might call it. It’s about having a curve which allows your front and back arm to sit in a natural ergonomic position while sailing, automatically positioning the sail at the right angle for the wind to enter and exit the sail. This position varies with the wind strength and windsurfing discipline, so each boom size needs to be developed accordingly.

Curve: The needs of a wave boom’s curve is very different from the curve for a slalom boom, just like a slalom boom for strong wind is very different from a boom for light wind slalom – one needs to offer control and the other power. Developing the right curve brings comfort and, respectively, performance.

Back End width: We have developed the correct tail width to suit each boom size and its uses. The width of the back end of a boom is very important – the wider, the more power; the narrower, the more control. We have studied each size to fit best the sail sizes it’s designed for.

Diameter: Diameter is another important factor as it does bring comfort to the forearms and reduces the energy wasted whilst out on the water. For our Alu boom we need to be sure to choose a diameter that will make the tubes stiff enough, and not bend over time. The wave boom 140 and 160 have a diameter of 27mm and 29 the bigger sizes from 180 up.

Stiffness: The stiffness of an alu boom needs to control the gusts as they hit the sail, and not just flex. Although we cannot expect the same stiffness as from a carbon boom, we can alter the tube diameter. By choosing a boom size which will comfortably fit the sail size, you will enjoy the performance of an alu boom.

Weight: You can have the lightest alu boom, but if these main features are wrong then the boom will feel heavy and uncomfortable. Too light and a boom could end up being too soft. The weight needs to be front oriented on the boom, leaving the tail of the boom light. A heavy tail-end will make a light boom in general feel heavier than it really is, so a light end is what is the most important.

Construction: monocoque built, including the tail piece with drilled holes.

Boom double pin clips for a stiffer connection between boom body and tail end, with 2cm adjustments. Different sizes used to best suit the boom size.

Boom head: Easy automatic fitting to the mast. Moving head tilts according to fitting height on the mast but does not move from side to side. With very little rope tension, the head will not slip on the mast. Fits RDM adaptors perfectly.

Boom Grip is lightly sanded, anti-slip pro grip: Less strength needed from you for a firm grip on the boom. Easy positioning marks for the harness lines.

Tail end pulley system: the wave sizes have the quick loop system, while the slalom sizes are having pulleys to host the adjustable outhaul system, or simple threading to fix the clew tension.
