It has been a rough year for the LDS. They usually fill the boat with plenty of lead time, but this year is different. With the departure date rapidly approaching, there are still quite a few bunks available and the shop is looking to fill them.
$495 will get you on board for four awesome days of diving. The plan is to motor down to San Clemente and work back up the islands through the week. I can only offer this deal through Tuesday (7/28) afternoon, after that, we cancel half the boat.
If you are interested, drop me a PM.
