Hyvässä slöörissä · sailing dinghy cruising

Customisations and Layout

Merisirri has certain additions to and deviations from the plans. Here is a summary of the major ones. As the building project is underway this list is likely to change.

Footwell. SCAMP seats are 250 mm (10 inch) up from the floor level. When sailing long distances it’s comfortable if you can sit your legs straight, especially if you are tall. Merisirri has a footwell between BH5 and BH6. This popular modification was included in SCAMP Mk II in late 2017.

Narrower cuddy doorway. This modification of BH4 was introduced in Southern Cross and included in Mk II. It have been recommended for better safety and convenience. Wider bulkhead walls also provide a good place for a bulkhead-mounted compass.

Compass. Even if we are living age of satellite navigation every cruising boat should have a traditional compass for navigation. Merisirri has one too on bulkhead 3.

Tiller tamer. When sailing single-handed there are moments when you want to get your hands free to e.g. read map or look for gear. Merisirri has a simple adjustable tiller tamer.

Navigation lights. At bow there is a 225° red/green bow light and at stern a 135° white stern light. They both are removable and operate on AAA batteries. The latter can be used as a 360° white pole light to meet all the relevant cases in COLREGS and CEVNI regulations.

Brass strips for centerboard, rudder and skegs. When a dinghy hits rocks the centerboard and rudder get damaged easily. To protect paint and plywood from damage there are brass strips attached to the front edges of the blades.

Stirrups. Actually this is not a customization but still mentioned here because of its significant effect on safety. When the boat is righted after a capsize getting over the relatively high gunwale can be tricky. The stirrups are a simple solution to that challenge.

Cockpit tent. What would dinghy cruising be without an option to overnight in the boat? In SCAMP cockpit there is space for one person to sleep on the floor or for two persons on an additional platform. Merisirri has a woolen tent for the cockpit.

Wider seat tops. The seats are 25 mm wider that improves sitting comfort.

Water pump. Water coming to the footwell has no way out. Instead of self-bailers the boat has a fixed manual water pump to keep the bottom dry. Water is pumped from footwell to centerboard box where it flows out of the boat by itself.

Foredeck handle. This may look like a bit peculiar addition to the boat, but in case of Wayfarer I have noticed that the foredeck is a popular place to sit at light winds. Scamp needs something on the foredeck that you can hold on. When approaching an unknown shore it’s helpful if there is a lookout at bow. The handle is also useful when securing the boat to trailer.

Boat’s layout plan can be seen below. The proportions are not accurate. The plan will be translated to English later.

Layout plan for Merisirri

When analysing Merisirri’s gear including a fixed eletric system in the boat was under consideration for long, but eventually it was discarded because of budget and reliability factors. The primary design goal was to create a carefree and maintenance-free vessel, and an electric system wouldn’t help on reaching this goal by any means. Also, benefit of any fixed electric device wasn’t significant enough to be as basis of justification.
