Boat maintenance
Do you own a boat? Maybe you don’t, but if you do, I’m open to invitations to sail away. Let’s make a deal; if you have one and find this tip helpful, you can thank me with an invitation. People who have boats should be wary of barnacles; harmless as they are, they can become a plague and slow your boat down.
A good helper for picking them right off is WD-40. When maintaining your vessel, you should always have a can near to spray on them so that they don’t grab onto the hull and become part of it forever. I will be waiting for your invitation.
