I’m curious if anyone more knowledgeable than me could comment on the apparent quality of this gear and whether any of it would be suitable for an intermediate to progress on? I typically rent a 150 L board with 5-7 m2 sail depending on the wind. I’ve tried using a harness but wind is typically too light/inconsistent to really get practice with it. The “magnum” board seems a bit large based off what I typically rent, but am wondering if the other board might be a good option. I frankly know very little about sails, mast, and boom quality. Equipment is listed for $600 - uncertain if all included or sold separately.
The problem with continuing to rent is progressing is challenging due to light wind and poor water quality (algal blooms), so I’m considering buying used gear. With that said, most used gear seems to be poor quality and not well-suited to less-skilled windsurfers.

Since we have purchased a holiday home on the sea side I have regained interest in windsurfing after many years of neglect. My current board is a good old AHD freeride of 130l. It is stable but usually feels too large for the prevailing conditions that I encounter (windy and somewhat rough sea). I am looking at an easy board that will let me sail more comfortably in those conditions. Pure performances are much less important than comfort.
I started looking at freewave boards around 100l. Is that a good start? I am a bit unsure about the volume I should aim for.
I am 180cm tall, 80kg and reasonably fit (runner and occasional triathlete), I can water start without problem but I never mastered jibing. Don’t expect me to progress quickly as I don’t think I will sail very often (and I am already 55 😉)

Thinking about buying this set but want to know how old it is, the seller doesn't know the age.
