Thanks for the detailed response
Im no expert but years ago we put 1200 hp in to an 86 scarab and the first thing tommy from chief recomended was bonding and glassing the seam. Ill put around until I ca afford a sunsation

GENERALLY speaking, the deeper the deadrise the smoother the ride in the rough. THe shallower the deadrise the faster the boat will be.
Very true but you also need more power to push a boat with a steeper vee which is why most manufacturers dont offer 23-24 degree on most boats--most go with a shallow V and a v6 or small block

Why is my response provocative? Bonding hull and deck with either plexus or metalchrylate adds structural strength for a boat that was meant to be used at high speed or run in rough water. Adding cloth and mat inside at the seams also helps. Having an inner liner also adds more rigidity. Capped boats are butt construction vs shoe box so they are bonded from the inside and done for looks for folks who don't want rubrails .DCB owners are one of those. Many older boats , including offshore style ones were built with shoe box method and only screws holding the hull deck together. Better ones had nuts/bolts every 6" or so and held together much better.
I've been around boats only 50 or so years, so what do I know. Sorry if I offended anyone with a boat that the builder chose to use shoe box method to build their boat and use screws only to hold hull&deck together,LOL.
Slamming into waves at 60+, bow acceleration puts tremendous pressures on a hull,1000\s of pounds per square inch causing the hull flex like noodle. This image shows load distribution on the hull with greatest stress points on the hull. You'll see more stress cracks in the forward section of the hull from the bulkhead towards the bow on some boats that were running hard. http://www3.telus.net/spectrasonly/load%20distr.jpg
Absolutely. I had an 80's Formula. The Deck was bonded to the hull, via glue, screws, and some thru bolts. In rough water, it was a wet noodle rattle box. My Fountain is glassed at the deck joint all the way around, and is much more rigid in rough waters. While this may not be as much of an issue in a short boat like a 25ft, it is definitely a concern as the length, weight, and speed grow.

MT, you still visiting Speedwake? Haven't been over there for a long time. Is the gang still active there? Does Jeff still has his Outerlimits?

Joe, fountains are bonded right? I was always unsure about that.

'Additionally, we are one of the few boat builders that takes the time to bond the deck and hull together with fiberglass as part of our six-step bonding process to create a unitized construction that is more durable and less likely to flex and break.'
