Just rented a Zarga 8.6 metre triple and it was too heavy to raise by myself. I tried to do it with the ladder directly being pushed right up into the air, but it's too hi gh and heavy to control and use. Would a rope ladder be better for 7metre+ ones. It also had one of those wide feet which was a problem as the ground had edging stones round a bed. A normal ladder would have been narrower and so dug into the bed.
