Just thought I'd post a follow up on this topic. I found a company in Barry Ontario that actual did some of the guard rail work for the Kelts build in Aurora. They manufacture ladders as well. I called and spoke to John who said he's sold
this ladder to other Kelt owners. I believe marineoutfitters.ca also stocks these ladders. At $140 the price is pretty reasonable. I ordered one and hopefully will have it installed this spring. I'll post pictures once complete.
