Cal 33'''' running rig
I am not familiar with Buccaneer rope but judging from its price I am assuming that it some kind of inexpensive double braid polyester. Double Braid polyester is generally too stretchy for halyards and jib sheets expecially on a 33 foot masthead rigged boat. This kind of stretch becomes a safety issue. In a gust you want your sails to remain as flat as possible but when you use stretchy halyards and sheets, the stretch of the halyards allows the sails to power up adding greatly to heeling and weather helm.
At the very least you should move up to single braid parellel core line like Stayset ''X'', a larger diameter Polyester double braid (minimally 1/2" or more ideally 9/16"), or else a wire/rope combo. For that matter you would be best off with a 3/8" higher tech, low stretch line.
I would be very suspicious of a rigger who has not given you the above advice
