Clarification please...one anchor point in between each boat (at shrouds?) AND one per boat centered under the bridle?
We're contemplating what exactly to do in our asphalt, mast up storage lot, already have the 4' helical anchors, permanent placement is under discussion with as many "plans" as cat owners.
We have mast up storage on our lake. We tie the boats down on the trailers. We tie the trailers to the ground. We have two anchors drivin in about 3 feet. The anchors are about 6-7 feet apart and in the center of the parking space. We've never had a problem with a properly tied down boat with this system. We've had plenty of really bad storms come through too.
