Ive been a boater on LSC for 18 years. 1st boat was 38' scarab for 9 years, sold that for 23' searay weekender with stand up cabin not cuddy for the last 9, just sold that for a 30' searay express. So heres my input from go fast boats and little boats.
The 38 scarab was blast to drive and sounded killer, sucked when you want hang out all day or it rains and cabin is only 4' tall, never used the porta potti because there PITA, would cost $60 to go to the muscamoot and back so I spent roughly $500 month for gas ($2500 for summer) . Wells cost about $2000-2400.
The 23 searay was way more fun with stand up cabin when hanging out all day, The pump out toilet and bathroom was awesome, your wife and kids will want this ($10 at gas dock to empty) On a busy weekend the 23 did bounce around abit but not terrible, the single 305 cruised slow but would only cost $20 to go to muscamoot back, never spent more than $500 for ENTIRE summer in gas. Wells cost $1200-1400. Obviously not as fun to fly around lake but had WAY more fun in this boat than the scarab and spent little money on gas.
I almost regret getting the 30' express, the big cabin and 11'6 beam are awesome but Im back to $2100 for a well and and maybe $1500 summer in gas. It rides like a dream and has nice cruising speed but not sure if its worth extra money.
I would try not spend 25K on your first boat, find a killer distress sale so you can get out from boat if you dont like it. (I paid $14k for my 30' low hrs and mint) I would look at 26' or so boat with stand up cabin and single 350 for economy. you can find a well on river for $700 or go to a marina for $1200 or so.
Ive been at beacon cove for most 18 yrs, went to Jefferson beach marina for 1 yr and hated it. most people swim at strawberry, muscamoot, or poor mans beach (in front macrays) Beacon cove has killer pool and its only 15 mins to all cool places, the only other place I would consider is Belle Maer Marina
FYI: there was a nice 1994 26' wellcraft excel on CL, aft cabin, radar arch, nice cabin, trailer, air/heat, it was sweet looking boat for only $15k, I almost bought that instead of my 30" and almost regret not getting it
Good luck
