the bigger fiberglass whips have more gain than the whip antenna depending on the model. The whip is a 3dB gain antenna.
gain is explained like this: for every 3dB you double your radiated power.
so...
25 watts X 3 dB gain antenna = 50 watts radiated power.
25 watts X 6 dB gain antenna = 75 watts radiated power.
you do want to go with the highest gain practical for your application but gain only helps on the Tx side.
fiberglass is not flexible, no biggie inshore and offshore. but if you fish around any trees they will break
It also depends on where you will be mounting it in your boat. I went with the whip antenna on a ratchet mount that clamps on my handrail. tucks out of the way and doesn't interfere with casting.
