I would be wary of the rubber surface due to algae growth making it
slippery.
A rough (as opposed to a floor smooth) 8-10 foot wide concrete ramp should
work just fine.

Hi all I'm a park planner for the Parks Dept of Columbia, MO. The city
is in the process of developing a 110 acre park that includes a 10
acre lake. We're designing in several kayak/boating features. One is a
"kayak lesson" area, basically a submerged concrete pad for the
instructor to stand in the water next to the student.

Another feature we want to include though is a put-in for
non-motorized boats. The put-in will not be accessible by vehicles so
all boats using it will be carried in. We're talking kayaks, canoes
and small jon boats.

So...

What make a good put-in? As of right now we're thinking a simple
concrete ramp approx. 8-10 feet wide, extending 3-4 below the
waterline with a "rubber surface" that extends to the waterline. The
water level in the lake is remarkably stable and wave action doesn't
appear to be a major factor.

Any critiques, hints, ideas comments would be welcome.

Thanks,
