26 Mar - Day #22. High overcast, 70s, 15kt winds S. Dingy in for showers. Interestingly, the mooring agreement with Fernandina City required that we put no gray water down our drains--no washing hands, brushing teeth, or heaven forbid, cleaning a dish. This may be the wave of the future. THe Yahoo LNVT Forum has an Interesting discussion on engine room temperature. According to Cummins the temp should no more than ambient +10F. Nellie is +40F. I then ran the bilge blower for a few hours. The delta-T stayed the same. The amount of air required for a diesel = 1/2 * (rpm) * (engine's displacement). A Cummins 4BT displacement is .138 ft*3. So, at 1600 rpm cruise we need 110cfm just for the engine. The winds pipe up to 30kts as we approach St. Augustine. Into the town docks—$1.95/ft ouch. 54 today: 809nm total. DBH
