If you want to sell your boat, I recommend you strongly consider the following three points to avoid disappointment and save time:
Get your boat ready first. Fix everything that needs attention. All maintenance and safety equipment should be up to date. Complete a proper list of upgrades and maintenance. Clean the boat inside and out like it has never been cleaned before.
Ask your broker for a realistic market evaluation using Sold Boat data and current market comparables. Full discuss your expectations of the time frame in which you expect to sell your boat.
List your boat at the lowest price you will consider and make it firm. A firm, but fair price will attract more buyers. Inflated pricing makes for stale listings.
