It was pointed out how the tacking up the shore improves your boat handling and boat on boat tactics.
Tacking against the tide also favours boats that point high so there is a difficult balance between reducing the number of tacks and sailing more into the stronger tide, going slow and high against low and fast, not hitting the mud and not getting pinned by another boat. usually you find that the fireball has beeten you to the windward mark or even the day boat.
On saturday we just went for the minimise tacks option and keep out of the way of other boats.
I'm glad you all enjoyed it. I will feed back to the club.
