I regularly stern tie our Kadey Krogen 42' - almost every weekend at the Butchart Gardens Saturday night fireworks. Here are couple suggestions.
1. Get There Before the Crowd: I usually make this trip at noon. It would not be possible to do at 6pm - it is a gong show by then. For your cruising, it might mean an early arrival at places where a stern tie is necessary.
2. Have at Least 600' of Floating Line: this gives the flexibility of the stern not being so close to shore. Ours is on a hose reel.
3. Set the Hook: get the hook set where you want it offshore. Take your time. With 600' you should be able to make the stern tie, bring the bitter end back to the boat and slowly pull the boat in. It may take a few trips between the anchor winch and stern line to get the position you want.
4. It is Not Mandatory to Double Back the Line: it isn't a big deal to tie off to a tree if that makes sense for the that spot. It means another trip in the next day but such a release is usually easy.
5. Go North of Desolation: not so crowded so we rarely use stern lines up north.
We are headed for Hakai Pass in one week!
