Saving Old Seagulls

What kinda small boats are we putting our gulls on? Round bottoms, flat bottoms, v bottoms, straight runs fore and aft, curved runs, etc? designed as row boats, sail boats, power boats, planing hulls, displacement hulls? Just asking, just curious. What shape hulls do gulls work best on? Or does it really matter?

seagulls were designed for displacement hulls

Although the smaller - short shaft seagull are suitable for rubber dinghys as later seagull brochures show.

I am currently running my flock on a 10' tinnie, with a relatively flat bottom. I am in the process of building a 12' flat skiff from Bataeu.com. Ply and epoxy. Very flat bottom. This is the boat I am planning on displaying my 102 on in the upcoming Australian Wooden Boat Festival.
