Can I find some places on the web to check out the value of my boat? Anyone have an idea what it's worth?

I have a fully loaded 1992 18' Olympic hardtop w/ oversized Easy Loader roller trailer with the following accessories;

Interphase Star Pilot 6 GPS
Interphase 500w dual freq w/ temp-speed FF
Uniden CB
Raytheon Marine VXL5150 VHF
AM-FM stereo w/ marine speakers
lighted compass
2- 8' whip antennas for CB and VHF
1- 3' AM/FM antenna
2 marine deep cycle dry cell batteries, new last year
1 additional battery for accessories(105 amp hour)
2 Canon electric downriggers wired directly to each dry cell battery
Powered by a 100 hp oil injected Suzuki V-4 w/ power trim-tilt from helm with an instrument cluster on dash
6 hp Suzuki 4 stroke kicker
It has a brand new steering cable and helm/wheel.

It's in excellent condition, stored inside of my garage for the last 7 years (when not in use), under canvas cover before that. This boat is a salmon slayer and has been treated well.
