2x electric winches mounted on the top pole/A frame, 1 is sky line the other is boat control/recovery,wander lead or remote control. I would make a light weight/low profile galvanized cradle that doubled as a launch cart with straps to fix the skyline permanently fixed to it.

This should tick all the boxes. easy to use, not spoil view, quick/ light to set up.

To do this nicely and make it last(saltwater corrosion) will take a bit of thought and money, if you were in england I would take it on as it would be an interesting project.

Whilst a skyline would be cool, in practice making it work would be fraught with difficulties, dangers and expense. Personally I'd file it under "lunatic schemes".

Couldn't you just build a permanent launch ramp using scaffolding and timber? It would make using the boat easy, wouldn't cost much, and if necessary could be removed in the future without too much difficulty.

Is this how you imagine it? If the sag is high like 1meter then the tension isn't so high but the mounting point by the house would need to be raised up to like 5+ meters? - pretty hard to have a winch up there.
Yes, similar. Particularly I envisioned an inverse pulley at the top of the pole with the winch at your operating level mounted lower down on the pole. In my world I'm also use to seeing offroad vehicle winches that have 12,000 lb pulling capacity, have remote control and are weather resistant. Not too sure how they would hold up in the salty air though.

Whether you use a ramp and bring your boat down or inflate it along the shore, it sounds like you will have people around, so either way, at some point, you're just going to have to say screw it if you're going to use a boat at all.

i genuinely don't understand why this thread has gone to such complicated and ott levels to launch a small sib?

surely, the method of least resistance would be best,

removable ramps, block, tackle, rope, transom wheels.

cheap if you use 6m extending alloy ladders with builders planking fixed with u bolts (even use wing nuts to remove if needed) so they don't slide, light easy to store in 99% of garages/ sheds/ green houses and take 10 mins to rig up or even leave ready to deploy at a moments notice next to the SIB.

couple of blocks & 100m of rope, reduce the lifting strain buy a factor of 3 and be able to pay out the lines in a controlled fashion.

all this talk of stressed zip wires, crane and so on seems somewhat extreme.

or am i talking out of turn, if so tell me to pipe down.

Would it also be possible to attach a seat to the zip line so once the sib is deployed, you can get into the seat and slid down yourself and jump straight In and off you go, no wet feet
