For the locals or visitors of Van Pugh
I have two Chinook 48cm SDM US cup extensions that need a new home.
They are free or you can make a donation of your choosing to the club.
They have served me well. I just no longer have standard diameter masts

If you have an older extension with smaller pulley wheels, the bigger wheels on these will make a noticeable effort in how easily you can downhaul your sail.
The older extensions either had an aluminum bracket with pulleys and built in cleat or the three pulley version that came after. These just have two pulley wheels and, unless you have a race sail, it'll be all you'll need.
Only one left
