Sport fishing charter/lease

For a couple of years now, I've been considering a sport fish.

I just can't seem pull the trigger, not knowing whether my family of five with three children 11 and under would enjoy it enough to justify the cost.

My broker suggested I find a boat similar to what I'm looking for and Charter for 2 to 3 weeks.

Our primary playground is the Bahamas, specifically the abacos and berry islands.

looking for something between 55 and 60 feet, preferably a Viking

Any suggestions on how to locate such a vessel to charter and take to the Bahamas for a few weeks? Not bare Boat, with Captain but no mate.

we spear with a little bottom fish, deep drop and troll for mahi/tuna

Thank you
