So I did, printed it, and went out to the garage to try it out. My existing
arrangement had separate pulley systems near each end of the kayak, so the
idea of only having to pull on one rope was attractive.

After about half an hour it was all rigged, with the free end of the rope
coming down near the stern. Start pulling and - up goes the stern, but the
bow stays sitting on the cradle. At the point where the rudder was about to
wipe out a light fitting I stopped (another reason for not having a
rudder?), but the bow had still not started to lift.

The rope is 10mm diameter, and the pulleys are ex a yacht, good quality and
the appropriate size for the rope, so excessive friction is not the problem.
I cleated the rope, went to the bow and lifted it until the kayak was level,
and it was quite stable, but when I hauled on the rope again up went the
stern only. It took three trips to lift the bow to get the kayak high enough
and keep the light fitting intact. A second person stationed at the bow
would solve the problem, but I don't normally have one available when I want
to do my lifting or lowering.

With something as light as a bike this system should be fine, you could pull
on the rope with one hand and guide the bike with the other hand if
necessary. For single person operation with a kayak it is not so
straightforward.

Now if I fitted a double pulley about half way, and ...................?
