Welcome Aboard. I hope Jasper is kind to you and perhaps the Golden Star you have in mind.
I`ve no direct knowledge, it seems a fairly typical sundeck style semi displacement "Taiwanese Trawler". They are usually rated as a "coastal cruiser" in suitable weather, rather than ocean crosser.Your use puts you well offshore. Sometimes surveyors certify for a certain distance offshore, insurers may follow that or have their own ideas which limit the covered scope of use. You want to be insured.
In context of the thread I began about the sinking of the Eliza 1, it does look to have some weight up high. On the other hand, it`s been around a long while without falling over. Boats can often endure worse conditions than their operators.
Might be worth posting a link to the advert, there are other Aussies with much more expertise to contribute.
