Lindacc ... The challenges of trailering your boat and what to do with the mast!
This is always a challenge but there are lots of resources to help. Youtube has videos and then in the "show more" section links to more detailed instructions.
I am not familiar with your boat but presume your mast has a tabernacle so that you can easily rotate the mast.
Check out the videos listed below and I'm sure you will see the basic concepts.
Tieing the mast down for transportation can sometimes be a challenge so that the mast does not bounce up and down with every bump. I have a larger O'Day 23 and, after lowering the mast, would always remove it from the tabernacle plate and rest it on the bow and stern pulpits and tie it down for transportation. This was a 2 person operation.
Anyway check out the following and you will get an idea of the basic process.
A couple of other comments
1) Always loosen the stays a little so that they can rotate easily as the mast is lowered.
2) When raising the mast make sure that the turnbuckles are aligned so they can rotate. It is easier than you might think to bend the turnbuckle screws when raising the mast. This can be an expensive mistake since you will have to replace the stay.
3) There has been lots of discussion on this website about raining/lowering the mast. Do a search and I'm sure you will get some additional ideas. Also check out the Trailer Sailer portion of the website for additional comments and suggestions.
4) Practice practise practise. When I first got my boat it was on the hard and I raised and lowered the mast - with a couple of friends on hand - so that I got the rhythm of doing it and what to look out for before I was actually at the launch ramp and doing it for real.
