Since you do not have a hardtop, they will need gunnel mount's, you can get them used on eby often, or buy new. you need to know what size adapter baseyou have...brand helps but is ot necessary. You want them mounted just aft of the bow rail, on my 22 they were just aft of the fuel fills, about where the cockpit seats/boxes against the helm chairs start. I would perfer them a little forward of there, even with the side of the cabin if room isavilable....but acces may be a pain, having them mounted where aft of the fuel fill is easiest since you have access to under the gunnel for mounting. This is about your only option without a hardtop, wishbone stlye mounts would be too big for that boat and would be in the walkarounds way. The only bad side to gunnel mounts is that the are in the way when not in use I feel, mounting the forward a ft or so would get them out of the way but woul be a hard job to do.
