We hired a cab when we went to stay at Playa Hermosa. Beats a bus any day. And yes you can carry boards in the cabs. Mine was actually a van. Several places to rent boards in Jaco. Though they all looks like potato chips and Hermosa is known for broken boards. They may have boards at Esterios and they have boards in Manuel Antonio. Remember Antonio really only breaks at high tide. I only had my 7'7 fish sometimes felt over gunned and undergunned. Had the chance to surf Boca Barranca when it was 14 ft at Hermosa. Awesome left.
