I would think somebody with a 250 WK would have some [variable] idea of the depth of water you need to launch a WK and retrieve it with whatever trailer is in use and post it here to help out sailors with
wing keels that they are new too. JMTCW.

I'm sure there are variables here regarding how much it takes to float your boat in relation to the ramp being used. No doubt every trailer sailor WK owner will have a different response given their experience here. From my experience it takes a depth of water, bow to stern, of at least 5' to 5'6" to float SP off of the trailer. Greater depth is always better.

I won't launch unless I know the front pads will be completely under water by several inches. I use a weighted line to sound the depth of the water until I locate where along the dock the front pads will be, then pace further down the dock to make sure my wheels aren't going to drop off the end of the ramp. I used to have a line made up with weights & knots at the appropriate places to make this easier, but I don't know what happened to it.

I learned this the hard way on my very first launch. I figured I could launch SL like all my other boats and friends boats, by backing down until I thought it was deep enough and standing on the brakes so it would slide off the trailer into the water. This was not a good plan, and I don't recommend this method. We now do strap launches.

Thanx David, That should be a start for these new WK sailors.

I know slope angle and ramp length play a role also.

I figure 6' for water depth, but make sure you still have a ramp at that depth. I use a 20' extension on my trailer.

Then there is always the option of using a travel lift off the trailer. Trailer never gets wet, but $$$

We do what David does. Put the pads a few inches underwater and the boat slides off. We use about 40' of strap to do this.
