The cockpit of the L450 gets really wet from three sides. This is the weakest part of the L450 we tested over the last to weeks in the Windward Islands
. The reasons are:
1. The openings for the stairs going up to the fly bridge let a lot of rain into the cockpit sitting area.
2. The roof sides are close to the seats. The water runs down from the roof and clings to the underside of the roof which is sloping forward. From there it runs along the slope towards the stairs to the fly bridge. On the way there many drops don't make it and fall off. Thus you have a curtain of water hitting the flat deck next to the seat backs. The resulting splashes make it far inside the cockpit.
3. The aft of the roof top ends right over the seat back of the aft table seats and the head rest of the lounge, so they are directly in the water falling off the deck.
The only place that stays dry is the seat next to the door from the salon.
Going inside does not make sense when in the tropics as there is not enough air flow as you have to close the front windows in the salon as well as the water runs down the forward deck right through them into the salon. It is unbearably hot inside. So we ended up standing in the middle of the cockpit when under anchor
until the shower stopped. Then we quickly went to the fly bridge under the bimini to enjoy the breeze.
Lagoon should have put more thought into the design details of the cockpit roof (hard bimini) to avoid some of these problems. A rail along the side of the deck should have been implemented to lead the water to one spot on each side next to the stairs. There a pipe should lead it to the deck level from where it can run off without splashing inside the cockpit.
What can be done?
The openings to the flybridge stairs can be dealt with by putting up the factory fabric
covers, but it is a pain to do so when you have showers going through and in between them you want to go onto the fly bridge.
Putting up the window side covers is not an option in hot climates as it gets way too hot with the cooling
breeze locked out.
To keep the aft seats dry I plan to install the solar panels
over the aft of the cockpit roof. I will then add a piece of fabric
between the roof and the solar panels
to prevent the rain from going through that opening. All the water will be lead to the aft side corners of the roof now. See extra post on the solar panels
in this threat.
The sides get more difficult. I will experiment
with a plastic edge running from the aft of the cockpit deck edge sloping forward to the fly bridge stairs. There I will have to catch the water and lead it off the deck. If nothing else the splashing will be located in one spot on each side at the stairs and keep the rest of the seats dry.
Are there any existing L450 owners that have dealt with this problem? Let us know your solutions.
