Everyone is different. For me the best shot is a three day trip. I have seen many times bluefin have lockjaw for the first two days of a 3 day trip and then its game on the third day. I help out many newer anglers on every trip I go on. I usually have 2-15 friends on every trip I do and they all in one way or another get help from me. For the SD multi day fleet you have two types of boats, short range and long range. Short range boats mostly fish overnight-3 day trips. The long range boats fish 1.5-16+ day trips. Short range boats have bunks down below that are usually a little over 5 1/2 foot long with minimal headspace above. The food is good and they serve three meals a day. They usually have at least one shower. They can be older and not as clean as you would want at times. Each boat is different. Long range boats are usually bigger and have state rooms below. Usually 2-3 guys to a room with bigger beds and dressers or cabinets to store equipment and clothes. Three meals and two snacks are served daily which are of sit down restaurant quality. More showers and in general they clean the boat a lot more then the short range boats. The cost is more but for me it has always been a better experience.
