I don't think you have any choice but to go anti-clockwise if you want to visit
Antigua. The winds in April vary from E to SSE, so it's a beat the whole way against
wind, waves and
current. It would take pretty much a full day/night to get there.
If you go anti-clockwise, the beating is SXM to St Barths (short hop), then
Nevis to Antigua (9-10 hours to Jolly Harbour). The passages between
Saba, Stacia St Kits and
Nevis are short open-water legs with motor-sailing in the lee of the islands.
Here's a suggested itinerary:
Ile Forchue - lunch stop, snorkeling, hiking
St Barths - French, restaurants,
shopping for the ladies. Bring a fat wallet
Saba - rolly moorings; snorkeling and hiking are good there
Stacia - rolly anchorage; hiking, site seeing
St Kitts - Brimstone Hill is the best preserved fort in the
Caribbean
Nevis - Sunshine's beach bar, some very good restaurants, hiking
Antiqua - motor-sail upwind for 10 hours, lots to do there
Barbuda - solitude, turquoise
water and an 11 mile long white sand beach
if you leave Barbuda very early in the morning, you can make it to Phillipsburg, St Maarten before dark. Or, you could stop at St Barths.
Leave some time to enjoy St Martin/Maarten. Grand Case for the restaurants, snorkeling at Roche Creole, Tintamarre.
Check out Chris Doyle's Cruising Guide for the
Leeward Islands for a lot of very good information on each island.
