Re: Anchor weight for 1650 Ib boat...
My Manson Supreme 25lb anchor was about $165 on sale. A Lewmar Bruce-style for this boat (33lbs) costs about $100-$130 (sale/retail).
For me the improved design and not having to haul up the extra 8lbs is well worth the extra $60 that I paid.
Claw anchors aren't as effective per pound, so the price comparison can end up being pretty similar. My examples are clearly for my bigger boat. For some reason it looks like both Rocna and Manson anchors don't get much under this price as they get smaller (my local supplier charges more for a Manson Supreme 15lb anchor than 25lb anchor), so you might not be as lucky.
boats that I sail on regularly: Pearson 28-2, Rondar 505, Yankee 30, Blanchard Junior
