I'm going to have my used Hobie 21 Sport Cruiser on a Lake in Minnesota for 1 week. I'd like to leave it on the water on anchor for the week, but I'm wondering if that too much time in the water? How long is OK if the water before damaging the hulls.

Also, do you think it is OK to attach the anchor to the middle of the front crossbar or should I rig two lines off off the forestay connectors at the front of the hulls?

Thanks, Doug
