Sounds like meThe Panamanians didnt give a stuff about cruising boats
I do however have an interest in Aluminum boats. I spent maybe about 7 years working on aluminum work boats 45-70 ft, mostly salvage and fishing vessels. Folks know why they make modern working boats out of aluminum right? Because it can take more punishment than fibreglass. It does however, also require more skill to maintenan and is trickier to repair and is more expensive.
I have seen my share of damage, and been there for my share of repairs, in some fairly bare bones yards. It doesnt take a highly specialised ship yard to make a repair. If a ship yard is repairing cruise ships, tankers, local ferries, they should the equipment and the tradesmen to handle a small aluminum plating job.
The German marina thing is weird, I didnt watch that video. Its possible that the professional yard was simply too expensive for her. If she has a repair budget of $8000, like some one said, thats not going to go far. A repair budget that size could have caught up on her on a fibreglass boat too.
