NAVIMAG ticket for sale

Hi, I have a NAVIMAG ticket for sale for the 30th March sailing to Puerto Montt from Puerto Natales. The cost of this ticket was US$355 but I am prepared to sell it for US$275 (US$80 less). This is a fantastic 4 day sailing through the Chilean fjords which I completed last year and had intended to do a second time round until my plans changed. If you are arriving in Puerto Natales in the coming days pls enquire at Erratic Rock hostel. I am going to Torres del Paine on Sunday and can leave the ticket at the hostel if you are interested. Boarding takes place on the 29th March and the ship leaves the next day - it is currently booked out. Will check for any replies to this posting tomorrow prior to setting off for TDP,
Evan
