Adjustable outhaul.

Sooner or later you'll find out that the possibility of trimming the sail flat or deep while sailing is a necessity. With an adjustable outhaul it is (after a short learning period) easy to trim the sail while planing. To trim the sail more or less powerful is very convenient and give you a more safe feeling on longer trips with the inherent risks of weather shifts - and the trim possibility is quite necessary, if you hope to leave your sailing mates astern.

Most of the bigger booms are provided with some pulleys in the boom tail, from where the string can pass the clew eyelet a couple of times. The problem with this is that too much friction can build up between the string and the eyelet, and at this place most sailors choose to mount a Chinook "double pulley" in the eyelet. This solution, however, isn't without problems either, as the string along the tubes from the boom tail to the cleats easily interfere with the Chinook pulleys - and then you can forget all about trimming the sail. The solution might be to force the string closer to the boom tubes - and a couple of suggestions are shown below.

Here the string is forced closer to the boom tubes by means of a couple of eyelets, fastened to the tubes.

Here the eyelets are made from a couple of "Nautix Clam Cleats", where the teeth have been removed by means and a saw.

In this instance the string is forced closer to the boom tubes by means of a couple of extra pulleys.

This is probably the better - but also a bit more elaborate - solution. In this case the placing of the pulleys has made a little rebuilt of the boom end necessary.
