Hi
If your post is what you are offering then yes, you will have problems getting a berth.
If you letter said something more like: "
Obsessive-Compulsive Cleaner/Polisher for any boat heading South! OK, I'm not that bad, but I cook and clean and will have your boat shining better at the end of the passage than the beginning. Experienced, mature, male who is relishing more longer passages.... (etc)"
Remember what advertising is: Don't sell the bacon, sell the Sizzle!
Don't put your age in - unless you are female and 22
Don't talk about you, talk about them, and how you will make their voyage better.
Even delivery captains want crew that polish because a Delivery Captain who hands over a brothel doesn't get as much work as one who hands over a gleaming clean sailin machine....
