I sail Victorias, and most people have drilled a hole in the transom and put in a rubber plug. In a breeze, they can get water inside through the various openings, even if sealed well. Drain the hull after every few races.
I put a drain in the bow of my 1 Meter (similar to other boats @ my pond). A small, rigid tube at the very tip of the yacht extending 1cm above the deck.
Until you get to drilling that hole, perhaps you can use a sponge on a stick…like an aquarium glass cleaning gizmo or a turkey baster. The other question you had about servos is “yes”. After about the 1 meter mark, most larger boats, marblehead and up, incorporate a servo to control the jib boom seperately from the main.
in a heavy air, all my boats, from the rg up to the ec12 get water inside… I have drain holes on the rg and the victoria, the soling and ec12 I use a syringe the soling is my driest boat. probably because of the raised cockpit cover…
if its a light air day IE no rails under water and you are getting water I wood look at rudder post or keel post.
If the deck gets wet water can get pumped inside by the movement of the sheets through the deck fairleads. If you do a lot of heavy air sailing, or have a tender boat, a fairlead that rises a bit above the deck is a good idea.
