Here are some hull weld close-ups. Only three attachments can be included in each post, hence the Part 2.

This is definitely a working boat.

An intriguing boat ! This definitely has its origins in an Alwest.
It looks like the engine compartment was cut off and moved back maybe 10 ft. You can sort of see two vertical seams. Those Volvo duoprop outdrives would indicate replacement of the engines.
The changes to the chines would give more buoyancy aft but would actually "flatten" the deadrise, likely needing even more power to get up on a plane. (See David's analysis in the tech section)
The deeper fin keel is perhaps the most interesting part. I have often wondered if this relatively simple change would give more slow speed directional stability to these boats. As we all know, as soon as forward motion stops, we are totally at the mercy of a crosswind. It is amazing how much crosswise resistance that original 4" "keel" does provide . . . as long as it is moving. Sort of like an ice skate blade, I guess.
That is quite the "offshore" bow :-).
