Continued this season's longboarding using a 24" Dura-Gold Longboard with 80grit Dura-Gold Roll Sandpaper . When I arrived the jackstands had been moved. Longboarded the areas where the jackstands were located, the front edge of keel, and some additional work on the first third of the bow, both sides. Felt rather wrung out, even at the start. Warmer today, mid-50's and more humid. Completed "first pass" (only pass?) over the starboard side of the boat, but for the underside of the keel and the turn of the sides into the keel. As per routine, wearing Full Face Respirator , gloves with t-shirt and jeans under the Tyvek suit.
This year, tried to use the longboard with more even pressure. By pushing harder, the portion of the longboard directly under one's hands will remove more material then the rest of the longboard due to the longboard's bending. Tried to have the longboard remove material along its entire length rather than removing noticeably more material where one's hand pressed the longboard to the hull. The result is visible in two ways: first, the longboard is more evenly coated with sanding dust; second, there more bottom paint remains on the hull after sanding due to not pressing the longboard into the low spots where the red bottom paint remains visible.
In the past, I've focused more on removing all the existing bottom paint (red), perhaps at the cost of sanding deeper in those low areas where the bottom paint remained.
Note: the bottom colors are, from the outermost inward:
