ATLANTIC HALIBUT!!!!....I am not worthy....
Dunno if you've done overnight canyon trips on other boats. That experience helps.
For me, doing canyon trips on MY boat is the culmination of 50 years of fishing. Starting with bluegills in a pond, canoes, tin boat, head boats, friends boats, 20 footer, to my 265.
Be prepared, learn what weather pattern works for your area, pick your perfect days (work and life schedule be damned) and go for it.
and remember...you will never run out of gas AT the canyon.... you will run out 5 miles short of the inlet...so stop in Edgartown for a beer...
