Beau will be hard to beat.

Thats a lot of numbers...one thing that i think comes out of it it there are some serious advantages in craft. I punted out the 23.5 LE, 26 LE, 26 Jav, 2014 x24 sprint.

If u really want to be competative and your at the pointy end of speeds. Boards make a big difference. fullstop.

It will be very interesting to see when we run the 500m if the same diff in board speeds are seen, to the same degree... or even more so, as it will be hard to muscle a slow boardon the plane for 500m...

its a real eye opener for me. id encourage other manufacturers to get their fast flat water boards to the next session, im happy to punt any board down course with unbiased effort.

We ran 1 at a time, in lane 2. it was fairly protected, and only running 1 at a time allows everyone the same conditions. There is no current. cant wait to do 500m.

What about the water depth, is it a constant depth of over 2 metre?
We have our little spot down here, its only 200mtr, but it is deep water at high and low tide.
The other course is only a high tide run because when the tide drops the speed goes down.
The chanel starts off ok but then shoals rapidly and you feell that some one has grabbed a hold of the tail of your board.

It's an Olympic course. Apparently kayak worlds will be held there in 2016. It flushes with the tide but has a wier so only fills on a really high tide and would barely have a head difference of a foot maximum.

What do you mean by hull speed and where did you get those numbers?

Hey boardbumps, the regatta area of the lake was designed with a constant depth of 4.5m - so even with some sediment build up over time, shoaling isn't a factor there.

Also, I'm pretty sure that in addition to the infrequent tidal exchange, the lake has a pumped inflow (for 12-20hr/day) from the Mooloolah River system connecting to its northern end, and corresponding continuous discharge into Currimundi Lake to its south to ensure there is sufficient flow circulating through it to maintain water quality and prevent water from becoming stagnant, outbreak of algal blooms and probably assists in biting midge & mosquito control too.

But this flow rate is very low in comparison to the overall lake volume, so is unlikely to have a huge impact on paddling times. The lake is very open and exposed so even a light wind (say 5-7knots) would have more influence on recorded times than the base flow on most days.

Nonetheless, on a dead calm/glassy day (very rare in the afternoon) it would be interesting to run sprints in both directions and see how times compare/average across the field.
