DE Ramp certificate is for boats with out of state registrations. If your boat is registered in DE you dont need one. Unfortunately you can only buy the certificate which is good for a year. I dont mind paying to use a ramp but I am not going to pay $35 to use it once plus $50 for fishing permit. Unless I know I can do several trips that is a lot to pay for just taxes for one or two trips.
In fairness Maryland is getting bad too. I heard that some parks on the Chesapeake are charging out of state people to use the ramp and then to park their vehicles. You also need a license to fish the bay. However, you can buy the license for a day or a week at a time for less. I think the park ramp fees are like $5 or $10. I buy a season long pass for SPSP at $75 per year but that is access to the whole park. It is only a few dollars to launch your boat there but they do charge per person to get into the park in the heat of the summer months on the weekends. The fees are the same for all.
Sorry DE, but your taxes prevented me from spending money in your state as I am not paying all that tax money for one or two trips.
