Jason,
We have a 45Lbs Bruce and I've used them on previous boats with great results. They set easily and hold well. In soft mud or sand your
fortress is probably a better option but that's just an opinion. We have a very large
fortress style
anchor as our storm
anchor and a bruce for daily coastal cruising. I've also found that you can find a bruce used fairly easily if you know where to look. I think you'll find that more chain is going to help with any anchor. I'm not sure if anyone told why you want more chain or if you've figured out the concept on your own but if you don't understand why you need more chain you should ask. I would also say 50ft would be a minimum amount of chain for a 38ft monohull like yours. Our entire
rode is chain which we use with a high strech nylon snubber. I doubt our anchor has ever been pulled any direction but horizontaly due to the weight fo the chain. Having said that, all chain
rode is heavy, expensive, and totally unneccessary. What can I say, it came that way. And by all chain I mean 250 ft so in many anchorages we don't get to the nylon rode.
Some mistakes I see made all too often:
1)People buy "high strength low weight chain", the whole point of chain is that it's heavy. Buy the cheap heavy stuff
2)People are to worried about weight. This I can understand, so maybe only get 50ft of chain but you should put up with the extra 10lbs to get a slightly bigger anchor than is recommended
3)People neglect to get a
windlass due to cost. Get a manual one. They're cheap adn it could save your boat some day, I can think of dozens of times that it could be important.
4)When people say back down on your anchor once it's set, really back down on it hard, especially if you're expecting a blow. If it won't hold, try the fortress. Better to find out on your own terms.
5)Think about the tides, if you set a scope of 6:1 at low tide it might be a lot less at high tide (or break free in the Bay of Fundy

). Remeber, the idea is to pull horizontaly on the anchor, thus the need for more heavy chain.
