If I were you I would take a photocopy or drawing of the bulkheads, and any other parts which are not specifically drawn on the plan. I don't think I have seen the Lesro Pilot Boat plans for sale around anywhere - they're not on the Lesro car site - and so I think the boat is quite rare. It would be a good idea to save the plans for selling (or posterity, should you wish to make them available). In either case, the bulkheads are usually not drawn on a Les Rowell plan, so they will be a valuable addition....
