I usually dive in normal scuba gear. I scrape with a paintscraper while holding on to the hull with suction cups but this won't do for really large boats with a draft over 30'.
The job will take to long and therefore become to expensive, the draft is to deep (decompression time) and I'll lose direction when the visibility is not great.
I read on all the other hull cleaning sites that they use the armada system or something similar. This is a powered system that brushes the hull while sucking on to it and driving forward. With this equipment you can clean a hull like you would mow the lawn. It looks impressive but I'm sure the purchase price of this equipment will be impressive as well and I might not recoperate this.
I just wonder whether there are other possibilities or whether this equipment would be a good investment.
