Fine tactics are highly depending on the ruleset used. The one we use to game is Ganesha's Galleys & Galleons, whose mechanics penalizes the use of galleys when confronted to sail ships – or so it seems to us.
In Galleys & Galleons, you use a number of dice to activate your ships and make them 'do things'. When your ship is a sail one, movement is done by default due to the wind impulse – you don't have to roll any die to make it move, just to adjust speed or direction when needed. Contrarily, if running a galley, you must spend some of those dice to make her crew row – otherwise the ship remains pitily in place.
Galleys & Galleons does not provide for galleys to change from oar power to sail. It is a little annoying at first, but later you understand that this actually matches historical procedures – galleys furled up sails just before battle and only unfurled them down again to leave the battle(-field? -waters?).
Besides, by the historical times we are playing galleys had ceased to have a significant impact in battles; as for what I've read on that particular war, despite a large number of galleys was used by both sides, they were always deployed at rearguard and used for secondary tasks --such as towing a damaged battleship away from enemy guns.
In this particular battle, only the ottoman side deployed a couple of galleys; and these were used not to engage the enemy directly, but to flank and pose an additional threat on them --menacing to sum to any eventual boarding action, a task galleys do excel in.
Perhaps not the most historically accurate approach, but adequate enough to the ruleset we're using.
