In large part through Ron's efforts, the Lake Washington J70 fleet is growing at an eye-popping rate since its inception in 2023. With twelve J/70s racing on the lake during that first year. In 2024, an additional 8 boats materialized like magic. And increased the total to twenty J/70s racing on the lake out of the South Leschi marina. Ron has been racing with the J70 lake sailors since the beginning in 2023.

Ron is a great resource for the whereabouts of race ready J70 boats for sale, a World Class coach offering personal training and anything else related to competitively sailing the J70.
