Hi Nick,weve been to arillas twice and weve hired a boat 3 times,we have NO sailing experience what so ever and you dont get much when your there but weve had some really good fun.you can hire the boats from opposite the Marina Hotel,we hired it for 4 hours and paid 42.50 euros and 10 euros for the petrol.Its really good value for money.Just make sure you pick a calm day to do your sailing,the sea can get really choppie and really scarey,theres life jackets on board and they ask you to take your mobile(just in case) another thing DONT drink on board,and im talking about water,if you need the loo your in trouble.i thought id go into the sea for a wee but i couldnt get back into the boat.we ended up near agios georgios and a nudest beach.a very kind naked german man came to our rescue.anyway it didnt put me off and next time we go we,ll hire one again.have fun and stay safe, cx
