Hi Frank, and welcome to the Forum. You have just got yourself a great little boat, and I am sure you will have lots of fun on it.
There has been a lot written and discussed about the keel. If you log in and scroll down to Tech Reference - Parker 235- keel, you will find a number of articles.
Basically, the camp divides into grease/no-grease with a few other suggestions. Perhaps Jim Hamilton sums it up with 'technique'. I find it much easier in the water and I tend to moor with the keel supported halfway, but with my advancing years, raising the keel is no a piece of cake. You need to get over the winch and work it.
Should you find an easy solution - you must share it.
Anyway best wishes and good luck
