For what it's worth, in prepping a 40 foot Ketch
for an Atlantic crossing
and analyzing fuel
capacity, motoring versus sailing mileage, I replaced a three blade fixed prop with Martec. (I'd used Gory and Martec props and experienced none of the problems appearing in yacht club scuttlebutt.) In the Med I changed back to the three blade fixed prop to "punch through choppy seas". After several years changing back and forth, looking for an advantage, I settled on the Martec. More recently I bought a smaller vessel in Florida
equipped with a Maxprop. To me, Maxprop is a needlessly complicated piece of equipment
. When the first adjustment was needed, I replaced it with a Martec. It's simple, it works and if there is a thrust trade-off under power, it's not significant enough to bother me.
Hope this helps-Good sailing
