Eighty percent of the marina patrons own conventional-hull, open cockpit powerboats 

 and prefer covered slips. The marina obtained the slips from two different manufacturers 

 and is satisfied with the performance of both proprietary systems. The floating docks are 

 assembled into units referred to as houses by the marina personnel; each unit consists of 

 about 12 berths (number of slips is variable) arranged abreast under a common roof. The 

 Lighthouse Bay management decided to purchase the dock materials in bulk and do the 

 assembling themselves so that the maintenance personnel obtain a better working knowledge 

 of the docks. 



The most recently installed house was a 20-slip unit, and the inplace cost was about 

 $1,000 per slip. The maintenance costs on this system have been running about $3 per slip 

 per year on 200 slips. One of the biggest maintenance problems is the need to move the 

 shoreside anchor points frequently as the lake level varies. Each house is secured to the bank 

 by two cables, a hinged strut at one end of the dock unit and a hinged-gangway strut at the 

 opposite end. The time required to adjust all the 17 units is about 25 man-hours. 



The only other major maintenance problem is that caused by winter ice damage. 

 Although the lake remains frozen for about 6 weeks each winter, the resultant damage is not 

 serious enough to warrant the difficult task of dismantling and removing the systems for the 

 winter. Drifting ice floes or windrows have not been a problem at Lighthouse Bay; good 

 natural protection is afforded by the cove site and by the abundance of trees along the 

 shoreline, which break the wind. 



Some of the dock flotation has been in use for 8 years and is still in serviceable 

 condition. About 2 percent of the flotation units are replaced each year. In some cases more 

 flotation is added to a unit instead of replacing the old sections. 



The sUp occupancy at Lighthouse Bay has been 100 percent for the past 3 years. The 

 management attributes this partially to the marina's close proximity to a metropolitan area. 

 The rental season is from 1 April to 31 October. The summer cUentel are encouraged to 

 winter-store their craft at the marina, but is not demanded in the seasonal contract. In an 

 attempt to generate more winter activity, the marina management has completed the 

 installation of a heated fishing dock facility. 



Presently, 75 boats are stored under cover during the winter, and 20 are stored outside. 

 The covered storage facility consists of a 90- by 200-foot building with a heated shop in one 

 corner and a concrete floor throughout. Access to the winter storage area is controlled, and 

 marina personnel must be in the area before an owner is allowed to inspect his craft. 

 Practically all boats are winter-stored on trailers for the multihuUed craft, which are usually 

 placed on blocks. 



The marina provides all eight of the ancillary faciHties hsted in the marina questionnaire 

 (App. K) as well as tent rentals and camper hookups. The present docking arrangement 

 provides each slip tenant a camping area immediately shoreward of his assigned boathouse. 

 This arrangement is apparently agreeable to the patrons, as no one has suggested changing it. 



Generally, this is a fine example of a well managed and efficiently operated lakeshore
