Say Lost Parent, did you mean 25 knots of wind, as its usually not measured in kilometers? I see your C 30 has a dodger to help with spray. Guess U don't have time to shop around for a bimini. They can really help take the brunt of rain, as long as its not coming down sideways! W. Marine does sell a cheaper, generic bimini for under $300. Its not the best bimini made, but its a lot cheaper then a custom made model. Biminis also really help to not get burned & baked by the sun in the summer. I would take a shade over a dodger anyday in terms of usefulness. This may also be a good time to invest in some foul weather gear. Remember to go ahead & reef your mainsail before U get out there in the thick of things, which is best when a C 30 gets in over 15 kn. wind. Cheers, & enjoy the ride.
