100 lt will be perfect, at 93 kegs your not really going to be planning on the way out in 15 knots, 100 lt board these days turn awesome, i have 101 Severne Nuevo and it turns amazing.
Get a board with the volume under you when you plugging around, would avoid any of the Maui designed boards as they tend to have the volume more forward, east coast spots tend to mostly have no wind in the break so the volume under you in these parts makes a massive difference.
I would stick to wave boards as FSW tend to lose the fun factor once your on the wave and want to do tight turns and keep sails no bigger than 5.6-5.7
I'll second that.
Having 92 kg i had the Goya 2016 Quad 116 and 2018 One 116, both of the "volume forward" type of shape. Both not feeling big, ok for slogging, very nice tight turning boards, but not perfect for fast or powerless bottom turns, due to the fat rails forward bouncing in fast bottom turns and the low volume tail not carrying my fat ass through powerless wind/wave bottom turns.
The new 2020 Goya One shape is quite the opposite, much more volume and width in the tail and thinner thickness and rail profile forward. This shape has so much slogging and planing power that my 2020 One 115 felt (too) big in tight turns so that i changed for the One 105. This board ist spot on for me now, easy slogging and planing and turning tight
and wide nicely.
Best light wind board i had so far (despite being Maui designed

)
