Re: Keel Design According to Perry

Hmmmm, Id like 6' of draft on my current boat, and I have 5.5........maybe an added lead bulb and a 5' taller mast some day.........next boat hopefully has at least 7' for a mid 30' boat, and 8' of close to 40'.............oh, I also sail where BP does, not sure the last time I saw actual digits on the depth guage, usually it is "---" or "last depth 55' " or some such number......oh well.........joys of a glacier dug area that was a mile thick!

Re: Keel Design According to Perry

we can all only wish Marty.. the joys of sandy beaches and mud flats demands a more moderate amount of keel here on the east coast

Around here if your depth sounder reads 25' you scream and do a crash tack.

So true.. but of course if it's reading 25 feet it probably read off scale 2 boatlengths back.. so you know it's coming up fast - and it's probably rock...

It would be really hard to get used to sailing in constant depths of single digit clearances.. but obviously one needs to in certain areas...

Re: Keel Design According to Perry

Ron, come over to the East coast. We'll take you out in Barnegat Bay where it basically never gets above 10', and average is 6-8'. Don't worry, it's very relaxing.

Bob and Kevin, thanks for the post!

On Barnegat Bay:

"What's the depth?"

"Reading 6 feet."

"Cool we've got plenty of water, I was worried we're getting too close to the shallow area."

Re: Keel Design According to Perry

Try Florida Bay:

"Boating in the Florida Bay is a task for the skilled. Treacherous passes cut through long banks of mud and seagrass that separate the shallow basins that make up Florida Bay. Safe boating requires the ability to "read the water" as well as a chart. Shallow areas are not always marked, so polarized sunglasses are a key to reading the water. Having a weatherproof copy of NOAA chart #11451 is highly recommended. Visitors should know the limits of their boat. On average, the bay is less than 3 feet deep, so knowing the draft (depth) of your boat is important."
