Hello everyone,
Today we wanted a Yellowtail topper, and a yellowtail topper we got! By no means wide open, but enough yellows to keep everyone busy for a half a day. The hot ticket was the famed blue and white 6x yo yo iron, tried and true for years and still holding strong today.
All and all a nice day of yellowtail fishing to round out a great fall 7 day variety trip. It was really something catching
Yellowfin Tuna, Wahoo, Dorado, and Yellowtail all in one trip!
Unfortunately all good things must come to an end, so after our great Yellowtail topper we pointed the boat northbound to San Diego. We are very far from home so we have another day of travel ahead of us tomorrow
Another successful trip logged away here aboard Polaris Supreme!
Will report again tomorrow,
The Supreme Team.
For your chance at a great fall variety long range experience, we have a 10 day coming up quick with spots available. Get in on the action and sign up today!

Well Friday the 13th is starting out to be a great day for us. We have flat calm beautiful weather and are pulling in lots of nice big yellowtails. 40 pounders! There are also a lot of marlin all around us. Everyone is having a great time. We were treated to an awesome dinner last night of rack of lamb with a Bordeaux reduction sauce. Our new chef, also named Tommy has been wowing us with his culinary delights. He also made a lobster bisque that was simply the best. Well I have to get back on deck. There is still a couple spots open on July 28th and August 2 has one spot. We'll call in tomorrow.

Captain Ryan Bostian called in this afternoon at 3:30 PM with an audio update from the San Diego out of Seaforth Sportfishing in Mission Bay. Today we fished at the Coronado Islands and had very good action. Our 28 anglers caught 140 Yellowtail, 50 Big Barracuda and 20 to 30 Bonito. They were biting really well on the fly-lined sardines and surface iron.

After 6 months of fishing in the deep end it was nice to shut the main engines off and enjoy the world famous Coronado Islands. I have always felt that it takes 3 days or 3 really good boats to give the islands a proper check. Today was day one of putting the puzzle together. 1 yellowtail, plenty of bonito and rockfish. A 40 lb rod, a few yoyo jigs and an assortment of torpedo sinkers.
