  1. Ask SAIL: Steel vs. Fiberglass Hulls - Sail Magazine

    A fiberglass hull can wait months or years for attention, but the unrelenting nature of corrosion will severely punish the slothful steel-boat owner. If keeping a weather eye out for rust and dealing with it instantly when you see it seems like extra work to you, steel is probably not your best choice.
