Ok, Im gonna say it...

So let's look at some numbers here. Since I have a V21 and I know exactly where to find the numbers I'm gonna use it for example.

First the numbers for the Seapro 206 WA. The LOA is 4 in. longer. Weight is 100 lbs more. Deadrise 3º less and beam 3" wider.

Sea Pro 206 Walkaround Cuddy Specification
LOA 21’ 8”
Centerline Length 20’ 6”
Beam 8’ 3”
Approximate Weight 2400 lbs.
Fuel Capacity 75 gals.
Maximum HP 225
O/B Shaft Length 25”
Deadrise @ Transom 17º
Approximate Draft 14”

Next the V21

Compared to the Seapro, LOA is virtually the same, weight is virtually the same. The main differences I see is wider beam and less deadrise on the seapro. Two key factors IMO. I bet the entry on the seapro is not as sharp either, but I dont' know on that one.
