We bought one spool of
Samson MFP Floatline. I cut that in half to create two 300' stern lines. Be sure to use a needle whip on any of these lines, as they are slippery and will be wet.
In a close
mooring, such as Princess Cove on Wallace Island, in the Gulf Islands - stern lines can be doubled through rings, or other holdfasts, ashore. This enables retrieval without going ashore again as already mentioned
In a more open anchorage, such as Aitutaki,
Cook Islands - stern lines can be tied ashore, coconut trees in this instance. The full 300' length will be appreciated. This requires going ashore again. Or asking a friendly cruiser or local ashore to untie for you often works.
We stow each 300' segment in white-water rafting 'bow bags.' A mesh bag with draw string opening and webbing reinforcement designed for stowing line on rafts. Works great and takes up much less space than spools or reels, soft and
cheap. And can easily be stowed below. The line is only in the sun when in use. Just flake into the bag in such a way that the line can be pulled out without tangling. You-tube this technique.
Floating line for shore lines is valuable for a number of reasons. Mostly, it can be nearly impossible to drag a sinker line (nylon or dacron) ashore. Even if flaking it all in the
dinghy first. If the line sinks, it will pull out of the
dinghy faster than you move shore ward. Very difficult if rowing. Might tangle in the dinghy prop if motoring. Secondly, during this whole procedure the main
propulsion engine is likely to be running. And someone on
deck may need to use it to hold the boat in position. Again, sinking line threatens to foul the main
propeller. Thirdly, the line is highly visible to everyone else.
Have fun in the Gulf Islands. Don't miss Burgoyne Bay if it's not blowing from the west.
