I scares me that you guys are doing 40 knots somewhere that requires a 14 cm fin.
It's not that bad Martin, water depth in most places about a 1meter, weed grows to the surface, on correct tide clearance about 150mm from top of weed to surface, plus some floaty weed

That is until you get to the last 500m of the run then it's about 300mm +- 100mm of water. It only hurts if you crash

Location is Albany best NM run in WA, close second to Lake George, for now, until someone cracks the 40+ NM run at Albany
