I've tried it. It doesn't work. At flank speed they make some additional drag. But at turning speeds, they are sometimes more effective then the main props, which may cavitate at full throttle and low speed. The net result being slower acceleration when starting from a dead stop and slightly worse turning.
Also, it's extra complexity. Extra complexity bad. No one believes this until after they build and battle.
I meant to include myself in that group. I didn't believe it until I battled. So please benefit from our collective rookie mistake
Likewise. I still suffer from 'lets make it more complex!' but my lack of time lately has stopped it from being a major issue...
Post some pics, and make sure to ask questions if you are unsure of something, preferably before doing the wrong thing
I have all the parts cut out and ready to do dry fitting. Place an order today for pops and pump so when neaded I will have it.
I am fitting the frames and keel and sub deck. Question should the bottom of the keel be flush with the bottom of the ribs? Parts are very tight fitting so some sanding is required for a snug fight.
If they are a little tight I generally use a scrap piece of wood to pound them together or use channel lock pliers to squeeze them together. Because of the curvature of the hull, the keel will be a little below the bottom of the ribs, particularly at the stern. So don't make the notches any deeper or the deck will not be straight.
I did not build this ship for battling since I have no one to battle with. Here are some pictures of the build.
