Thanks for asking: That would be plenty. As a recommendation, I like 6-7 feet. I have seen boats on the bottom, from the surface (clear lake) Also with the gazebo we get a good topside view. with 6-7 feet your line and float might not tangle -up your team mates. Small ships could use nylon THREAD (or fly line) wrapped around a smoke stack with a small piece of styrofoam. I like BATTLING and I like DIVING -------- I try not to do TOOOO much in one day
I used the high tech solution of sticking a fishing bobber in my mast and tied it to my stack. You absolutely 1000% will want a float of some kind…
Looks good. With this idea you can test sink that piece of superstructure to confirm deployment Remember, nylon string absorbs water, lose bouyancy. FYI
Just as an FYI: Dacron/Polyester ropes do not absorb as much water. They have good strength, and are used in mountain climbing for that reason It is expensive, but no climber wants a rope that absorbs water and then freezes.
I have suggested fly line before, it was for a convoy boat. One problem with fly line is that it has some memory. I use it some times. When I am on a lake were I do not know the depth ( NC / Tennessee) I use nylon on a spool. I can carry a lot of line and it does not interfere with my boat operation. This of course is for larger floats. Smaller boats I use nylon thread.
