I'm trying to sell my boat myself and will add my thoughts on it.
It's effin ridiculous how much brokers want to sell a boat - 10%. For what? Most boats are listed on Yachtworld and the buyers narrow down what they are looking for. It's computer time vs actual visiting yards to find a boat.
In the case of Palarran, it's a very thin market given its size, age, and price. A buyer who is looking for a plus 50' cat for under $500,000 that is less than 20 years old has 24 cat's worldwide to choose from. Most can take 10 of those right off the list, which leaves 14 cat's to decide from. Three of those are sister ships, so not much for selection IMO. I've had three inquires in 4 months, so not a great response using boats.com, cruisers forum, and catamaransforsail.com.
After this winter season I'm going to list the boat with a broker, but only with a seller's commission, which is 5%. Again, IMO if you are looking for this type of cat, the buyer will do the research
on yachtworld and find it themselves. If they choose to use a buyer broker, they have to pay for them.
