Mushroom mooring for Typhoon

[Dick Villamil]

Does anyone have a recommendation for a mushroom mooring size for a Typhoon in moderately protected fresh water lake where the waves might get to 2 feet and winds may reach 20-30 nots on occasion?

[Jim Sullivan]

I kept the Typhoon that I owned for over 14 years on a 150 pound mushroom. I never had a problem. The conditions were much like you have described for your area. I would not go less than 150 lbs. It is important to have sufficient scope for the mooring chain(s) and pennant based on depth of water at mooring location and tidal changes if applicable. When I bought a CD22D, I upgraded the mushroom to 250 lbs. You may wish to purchase a heavier mushroom than actually needed if you plan on moving up from the Ty in the near future. Good luck. Hope this helps.

Maybe this will help.

AHYC recommended minimum sizes for anchors, chain and pendants.

You local yacht clubs should have something similar.

Dick,

You should check with the local community's Dept. of Natural Resources or harbormaster. Most towns, in New England at least, have regulations or, in a few cases, recommendations (like Cathy's AHYC table).

In my own town of Bourne, Mass., I used a 150-lb. mushroom for my 18-foot catboat; I went up to 300 lbs. for the 25D. In both cases, I followed town regulations, and in both cases the mushrooms proved adequate for a marine anchorage with tides, winds and so forth (not usually high waves, but sometimes up to 2.5 feet in bad storms).

The nature of the bottom which ultimately "holds" the anchor is an important determinant . A relatively light mushroom will hold well in muck but not so well on a harder bottom. I would ask the locals who have had boats in the same area over multiple years of weather conditions. I have a 100 lb mushroom for my Ty but it is in goo so sticky that I can't even get my wader loose if I stand in it. I has held well in gale conditions but it is a very well protected small harbor.

I have used a 150 lb mushroom on my Weekender and it has worked well. The weight was chosen by the local mooring company when I first put the boat in about 20 years ago. I have a mud bottom in the harbor.

I should have added that the bottom where I keep my mooring is gooy, sticky mud (more like muck, actually).

Thanks everyone - I will look for a 150 pounder and extra heavy chain since I do not want to pull the mooring very often!
