Both Herzlia and TA marinas
have full assortment of services in their boatyards
TA marina is smaller and more difficult to find place in (also more difficult to enter in bad weather).
TA marina have excellent location - easy access to all tourist services.
Herzlia is out of town, but has good transport services to Herzlia or TA. In the marina you may find restaurants, bar, supermarket, shopping
Although Israeli weather
permits sailing on most winter days, there are no many places where you may sail to (daysailing is excellent)
There is Akko (Acre) with small and crowded harbour and marinas
in Ashdod, Ashqelon and Haifa (Haifa is usually crowded).
BUT - a lot of interesting land sights to be visited by hired car or public transport. All within short reach. The furthest being Eilat on the Red Sea - 5 hours drive or one hour flight.
