For some time I have been meaning to change my 23" ali prop.... which only achieves 400 - 500 revs BELOW the recommended WOT, for a smaller pitched steel one.
Having finally decided to go ahead, the main choice seemed to be between a high rake Laser II or a more standard Vengeance. Andre has the Laser II and swears by it, but sought opinion seemed to favour the Vengeance for my weight diesel boat. Whichever of those 2 props I chose, in theory the reduction to a 21" pitch should give me the required extra 400 revs to get to correct maximum WOT
However, I then rang Steel Developments who recommended a 3rd option of the larger diameter 'Titan' prop, (apparently the Solas version of a Mirage), in 21" pitch. I was persuaded and bought one. Unfortunately, this has turned out to be not right for my boat; the extra diameter producing only 100 revs more. Due to the fact that, (for good theoretical reasons), Steel Developments suggested that prop, wrongly as it turned out, they have agreed to change it for another of my choice. Their suggestion now is that a 19", ‘Titan’ prop would be best.
So here is my conundrum.... Which should I choose? Steel Developments tell me they will only change it this one time, so do I take their advice and get a large diameter 19” prop. Go with the more common advice and get the 21" pitch steel version of the one I have, (i.e. the Vengeance) or follow Andre’s lead and get a Laser II?
Whichever I do, I will probably wish I had gone for the other but does anyone have any experience of the Titan… or the Vengeance versus the Laser II etc… on a 1,200 kilo diesel RIB. Andre has kindly offered to let me try his Laser II – (thanks mate!) but after that, I am choosing blindly and I’m stuck with my decision…..
Does anyone RENT props????
