I was a carpet installer in my younger days and Bob J, you're right about the carpet knife, but a good utility knife with sharp blades will do the job for the do-it-yourselfer. Those carpet knives are so sharp and a I thought a novice may leave some blood stains on his new carpet so I suggested the basic utility knife. I've carpeted vans, boats, patios, etc. and there are several ways to install carpet in a boat. You can do the tackless install, but the moisture will eventually get to it and will mildew and rot the tackless and the nails will rust. Also, tackless requires padding and if the pad ever gets wet, it will hold a lot of water. The 10,000 staple technique works also, but carpet staples are are brass and if they get wet, will stain the carpet. If you want to change the carpet in the future, try pulling out 10,000 carpet staples...they are very long and narrow and you have to pull them out with pliers 1 at a time. I've ripped up glued down boat carpet and its messy...no doubt, but I scrape off the large noticeable bumps of dried adhesive until its relatively smooth. Use an outdoor adhesive and lay in the carpet. You may need a few staples to hold narrow edges or vertical areas. One very important thing...never use any sort of rubber back carpet when doing a glue down installation or you'll be scraping off rubber pieces the rest of your life if you want to replace it later on. Use regular actionback carpet. Nylon is the strongest fiber, but olefin holds up ok. BobJ, your tackless installation may hold up just fine if it stays relatively dry, but sometimes that's a difficult thing to do on a boat, that's why I feel the glue down method will work better for most boats. I carpeted the cockpit of my friends Baja 2 years ago and it still looks new. If you glue down the carpet with an outdoor quality adhesive and it gets soak and wet, you just have to wet vac as much water as possible and then let nature dry it completely. If your tackless install gets wet, you have to rip up the whole thing so the padding can dry and have it re-installed. Oh, and another thing, carpet is sensative to humidity and when installed with tackless, you can get buckling in the carpet after a while and you will need a restretch. No buckling ever in a glue down job. Sorry for the lengthy dissertation, but I did this professionally for years and wanted to give the pros and cons of the different ways carpet can be installed in a boat.
