For a limited time, free nitrox is offered agents booking full- or half-boat charters; they are welcome to sell it, give it away, or use it as an early-booking incentive. This applies to all EV destinations. As an added bonus for full-boat charters, EV is offering a free familiarization trip on any EV Fleet vessel for the group representative. (Half-boat is defined as 50% of the boat’s full capacity.)

These offers can be combined with EV’s regular booking policies, which in many cases, are better than other DEMA specials. Some include a free berth with 5 paid (maximum 2 per charter), generous deposit terms—all fully refundable 12 months out, easy group reduction policies, alternative group payment plans allowing easier cash-flow management and payment by credit card, extra free berth on full charters departing within 12 months of another previous full charter, and off-peak charter specials (increased commission and double the free berths) available each year. Conditions apply. EV’s offer is for trips booked and deposited through November 5, 2011. DEMA special is valid any time except peak season in the Maldives and Galapagos. The DEMA special cannot be combined with off-peak charter specials or pre-DEMA specials and is not applicable to specialty itineraries or previously booked groups.

After group deposit is made, the free fam trip can be taken any time before or after full charter travel with 30-day confirmation for Caribbean and Galapagos, 60 days Maldives. Fam trips must be completed by March 1, 2013. If a fam is taken before the full charter travels and the charter is reduced or cancelled, the trip will be charged on final charter payment at $700 for Caribbean and 7-day Maldives trips and $1,000 for Galapagos and 10-day Maldives trips. Normal onboard charges, taxes and fees not included. Valid for shop/agency owner or full-time shop/agency employee.

The Explorer Ventures Fleet comprises 7 destinations including the Chinchorro Bank (Mexico), Southern Bahamas, Turks & Caicos Islands, Northeastern Caribbean (Saba/St. Kitts/St. Maarten), Galapagos Islands and the Maldives. The M/V Turks & Caicos Explorer II also spends 10 weeks in winter/spring offering snorkeling with humpback whales on the Silver Bank, Dominican Republic.
