GS: The tools I bring typically fit into a small toiletry bag: two multi-tools, a multi-screwdriver, a small crescent wrench, specific tuning tools for each class, a tension gauge, tape, tape measure, Sharpies, needle and thread, extra screws, yarn, a handsaw, and shackles. We do sometimes bring our Snipe shrouds and spreaders if we think the charter boat may not have the adjustable type we like. This of course isn’t possible with larger boats, but something to consider if you have a specific element you like (assuming you can easily remove and transport). The larger tools are all easy to check in a suitcase within the U.S., but outside of the States it may be easier to borrow them. I am diligent about returning whatever I borrow the moment I am finished to let friends know they can trust me with their tools.
