I'm sure that you do!

Ambitious, aggressive, creative, daunting fix! Me, I would fair them up nicely, including sharpening the edges and get her up on a wide open plane before deciding on spray rails and location. Squatting a little to stern is a LOT better than squatting to the bow! Again, congrats! Take a bow (pun intended).
PS: I finally 'got' it - congratulations on some interesting work!

Re: Bulbous bows
FG things are looking good you can always correct stern squat with trim tabs if you don't already have them. But man everything is starting to look good.

Re: Bulbous bows
FG, Have you managed a run on plane? The suspense is irritating my wife. Mostly because I keep mentioning it and she has no idea what I’m talking about.

Re: Bulbous bows
I tested the boat Thursday night up around 5600 rpms and water was shooting up onto the windshield, so we have to deal with and correct spray.

Re: Bulbous bows
I think you were correct when you mentioned spray rails but may consider reverse chins to keep the water from being forced up the bulbous bow. But the placement will be very critical. You will get it there.fallguy1000 wrote: ↑Sat Jul 15, 2023 10:43 pm I tested the boat Thursday night up around 5600 rpms and water was shooting up onto the windshield, so we have to deal with and correct spray.

Re: Bulbous bows
fg would have liked to see a picture of the outside spray since you say it is reaching the windshield. That is pretty aggressive spray. But either way I think you need an aggressive spray rail at the break carrying back to the hull where it bends under. Good luck to you.

Re: Bulbous bows
Is spray coming up through trampoline?

Re: Bulbous bows
Approx what percentage of the spray coming up through the tramp is deflecting off the inner hulls, and what percentage direct from bulbs?
