Increasing the deck - at the masik - would be fine. Just a couple of inches will make a big difference. Greenland boats fit tight, in any case, and that's good for rolling and bracing.

As for an adult sized SOF, that fits a variety of paddlers, I'm going to recommend my
Chuckanut 10 or 12 designs. They are 10'x27" or 12'x30" respectively, have large open cockpits with rounded chines and wide, nearly flat bottoms. Designed to be casual, comfortable, stable and easy to use for most anyone. PM me and I can send you the building guide, if you're interested.
Tom Yost's Sea Tour 13 is another option, though not as user friendly for the uninitiated paddler.

I'll include a pic of the Chuckanut 12 - several have been built, and reports are good!

Do feel free to ask if you have any building question with the Sea Pup!

Good luck!

: Hello Everyone,

: I started drawing out the plans for the Sea Pup today. I like to
: put it to posterboard first, then transfer to the plywood.
: However, I noticed the Sea Pup Deck is only a 9.6" tall. When
: I built the Sea Flea, I raised the 8" deck an inch thinking
: the original was too low.
: I was glad I did as it increased the length of time that my
: daughter was able to paddle the boat before she grew out of it,
: unable to get her legs in and out easily. So knowing she outgrew
: the Sea Flea with the 9" Deck, unable to get into it any
: more... Do I go ahead and raise the deck of the Sea Pup for her
: leg room? If so, how much should I raise it?

: Thanks for the opinions.

: You'll probably see me hanging out here again, as some of you may
: remember me from 2007, building my first kayak for my daughter.
: She is 10 this year.... long legged little thing, is demanding
: her new boat for the season..LOL. So we are starting on it this
: week. Lumber is purchased, and even bought some new tools
: instead of borrowing. Got the garage cleaned out a bit and have
: eliminated all excuses not to get this done in a timely fashion.
: (yeah, right!)
: I'll be needing a cheering squad as I muddle my way through this.
: Then Im hoping to move on to an adult size to build for misc
: tag-alongs that might like to go out kayaking with us at times.
: Havent picked which boat that will be yet... I could use some
: opinions on that too. Whats an all around, good general SOF to
: build for a wide spectrum of people?

: Thanks again... I look forward to hearing from you all.
: Warm Smiles, ~Heather
