The Axiom is the joker in our pack. It is not a folding propeller, but it does have a revolutionary blade profile and section, if you will pardon the pun, and has never been tested on a yacht before, so we just had to put it into our trials to see how it compared. As the photograph shows, the blade profile is rectangular, while the blade section is almost S-shaped, and symmetrical in ahead and astern, with no twist. Its designers claim it gives greater thrust and stopping power, together with lower wash. So how did it stand up? Well the charts show the story, with its stopping time nearly a second better than any other model, and its side thrust again the lowest by far. However this was at the expense of lower top speed, which suggests some more tweaking is needed, but it is still one to watch.
As both our amateur testers saw slightly better results with the Sub Zero over the “mainstream” Callaway GBB Epic which has to say so long as you’ve got enough launch you can seriously benefit from the Callaway GBB Epic Sub Zero ’s extra forgiveness (so long as the Epic’s 12g weight is in the back port). Callaway reckon their new Jailbreak tech increases ball speeds and we’d have to agree, as for two of our three testers it produced their fastest average ball speeds, and because of its such strong performance TG Ed Chris Jones has slipped one in his bag for 2017.
The Prop Protector cut the rope cleanly, and all the netting. It didn’t shred the netting but cut through it, dividing it in two, and would prevent your boat being anchored by a long length. When the polytarp was left to drift into the prop, it tended to get caught on the blades and just swirled around, but as soon as a slight amount of tension was applied, it was cut through. However, it wasn’t shredded and sometimes remained on the blades, which would reduce thrust. In practice, a large sheet would possibly apply enough drag to make the cutter work. It couldn’t cut any of the wires, though. The netting and smaller diameter ropes could sometimes be drawn down into the gap between the cutter and the P-bracket but reversing tended to loosen this.
