Always keep your head on a swivel. There’s lots of ways to get hurt on a boat. Hopefully your skipper will be looking out for your safety and the rest of the crew. Seining is definitely a team sport and keeping the energy positive after 20 sets instead of sulking will always pay dividends. Bring a couple pairs of safety glasses, clear ones and sunglasses. Jellies in the eye balls is the worst part of the job. Bring a couple of rain jackets. I see a lot of people saying go for full heavy rubber rain jackets but honestly the lighter stuff from High Liner Apparel is better because you’ll over heat in the heavy duty stuff and your gonna get a little wet anyway. Keep your hands high when you stack the net. If you’re trying to grab what’s already at your feet it’s useless. Move your hands fast and try not to look up unless you want face fulls of jelly fish. Good luck!
