Nothing really replaces getting out on the water in a given boat and paddling it a bit.
Im a bit heavier than you but generally the same hight. My first “nice” boat was a CD Soltice GTS in kevlar which is a delightful boat and I would consider taking a look at one if you can. CD generally makes great boats and mine was used, well kept, and has really stood up to some abuse over the few years ive had it. My only complaint is the lack of day hatch which has become really popular on boats in the past few years. The molded hatch covers have never been an issue and on the water is a delightful boat in all conditions. That being said its somewhat “uneventful” of a boat. Not terribly playful, not terribly planted in the water either but if you want an all around, go fast, fill it with stuff, comfortable, rudder boat, its exactly what you are looking for.
I paddle with one guy who has a Stellar 18 and one who is in an NDK explorer, we all hold pace with each other well, those are both skeg boats but thats a personal preference thing.
If you are looking for recommendations in that space I would take a look at the Prana from CD if you want a CD skeg boat. The Explorer from NDK (will be a bit heaver than the kevlar CD boats) either LV or standard depending on the fit you want. Valley also makes a variety of boats in that size range but I have yet to encounter one in person so cant speak much to them.
Ive got an NDK Greenlander Pro, but that is a whole different barrel of what ever is in the barrel today…
For day trips and short weekend stuff you can also look at the shorter 15-16ft boats that are out there like the NDK Romany etc.
